Anesthesiology and Algology Clinic

Anesthesiology services for all kinds of surgeries as well as diagnostic and interventional procedures are provided to patients of all age groups. 

Procedures at the clinic are performed under ultrasound guidance, and monitors capable of close observation of the brain and heart are used. During surgical procedures, echocardiographic observation of the heart is also undertaken by experienced physicians. All types of peripheral nerve blocks, which are required for different surgeries, are established under ultrasound guidance as well. 

Additionally, all procedures relevant to chronic pain and port catheter placement are carried out at our clinic.
In conclusion, we combine technological facilities with current knowledge and an experienced team to provide high-level and reliable service on all occasions where anesthesia is required.
Each patient referred to our clinic is evaluated prior to their operations either at the anesthesiology polyclinic or the ward where they are hospitalized. Our physicians select the most ideal type of anesthesia and postoperative pain management (analgesia) for the patient based on their history of previous surgeries, overall health condition, known chronic diseases, regular medication, allergies, upcoming operation, patient preferences and a number of other factors. For this purpose, patients go through specific laboratory tests, investigations and consultations after an in-depth examination and evaluation. The anesthesiologist informs the patient on matters to take heed of during the entire process and answers their questions. Our objective at this point is to make sure that the patient undergoes the planned surgery uneventfully and remains healthy and comfortable all along. 

On the day of surgery, the patient is accompanied by their nurse to the preparatory section. Information like identity details, type and region of the upcoming surgery, allergies and known chronic diseases are inquired and confirmed once more. Afterwards, venous access is gained, and a sedative is administered, if deemed necessary. The operation is then performed in a fully-equipped operating room under the appropriate anesthesia. All vital systems, including the heart, lungs, brain etc., are monitored for anesthetic depth using advanced monitoring equipment during the course of the operation. Once the operation has been completed, the patient is transferred to a special recovery room. All vital functions and pain status are closely observed until the patient is ready to be transferred back to the ward. So as to detect symptoms of pain and any possible complication, observation of the patient continues by a physician and a team that we are also a part from the moment they arrive at the ward and until they are discharged.
All surgical procedures, including special interventions like congenital heart surgery and liver/kidney transplantation, are performed by specialized surgeons under the required general or regional anesthesia. The units of advanced endoscopy, interventional radiology, diagnostic radiology, radiation oncology, delivery and in vitro fertilization all have their dedicated and full-fledged postoperative recovery rooms allocated for each patient. Our preoperative evaluation, postoperative care and algology team also ensures proper execution of basic principles of patient safety.

Emergency service is the unit where patients presenting with any kind of complaint are evaluated to identify conditions that might potentially result in disability or sudden death. Patients receive their preliminary treatments here accordingly. Early diagnosis of and interventions for the following conditions and problems are conducted at our emergency service: 

  • Early treatment and diagnosis of sudden-onset and potentially life-threatening conditions
  • Evaluation of multiple trauma cases within the framework of current algorithms
  • Injuries of limbs and organs
  • Lacerations and bleeding

  • Medical problems like stroke

Endocrinology, Diabetes and Metabolism

Patients most often present to our department with diabetes. A condition that follows a rapid course of onset and progression, diabetes may cause a variety of complaints like consumption of excessive amounts of water, frequent urination, weight loss and malaise. On the other hand, such symptoms may not be present in type 2 diabetes. Type 2 diabetic patients may present with bulking around the hip and weight gain. 

Furthermore, weight gain and associated complications (fatty liver disease, hypertension, muscle and joint problems, nocturnal apnea etc.) may be observed among those patients who have been diagnosed with obesity.

Symptoms such as tremor, perspiration, palpitation and weight loss could signal hyperactivity of the thyroid gland, while complaints like malaise, hair loss and bloating could indicate a hypoactive thyroid gland. 

Swelling in the thyroid gland may be due to possible presence of a thyroid nodule. 

Excessive malaise, hypotension and weight loss might be suggestive of deficient adrenalin function. The opposite can be inferred from excessive weight gain, increased hair growth and hypertension.

Irregular menstruation, lactation and decreased sexual drive can be due to too much prolactin being secreted. Growth in the hands and feet and hyperhidrosis could be associated with extra growth hormone secreted by the hypophyseal gland.
A subspecialty of internal medicine, the branch of endocrinology addresses hormones and hormonal diseases

Below are the primary hormonal diseases: 
  • Diabetes mellitus
  • Thyroid diseases (goiter and other types)
  • Parathyroid diseases (diseases of calcium metabolism)
  • Osteoporosis
  • Obesity
  • Hypophyseal diseases
  • Adrenal diseases
  • Gonadal diseases (polycystic ovarian syndrome, infertility due to hormonal disorders etc.)
  • Hirsutism (increased hair growth)

ESWL (Extracorporeal Shock Wave Lithotripsy) Unit

  • Renal calculi measuring less than 2 cm
  • Ureteral calculi (primarily calculi measuring approximately 1 cm, and also those measuring up to 2 cm)
  • Bladder calculi (in cases where there is no accompanying obstruction)
  • Pregnant women
  • Patients with uncontrolled urinary tract infection
  • Patients who are actively taking blood diluents (anticoagulant-antiaggregant) or have a condition of coagulopathy 
  • Patients who have an aortic aneurysm in close proximity of the target ESWL area
  • Patients with uncontrolled hypertension
  • Features of calculi
    • Count
    • Location
    • Composition and rigidity
  • Patient-associated variables
    • Anatomic features of kidneys and the body
    • Skin-to-calculus distance
  • Properties of the device used
  • Experience of the practitioner
  • Cooperation between the physician and patient
ESWL is a procedure that is usually tolerated quite well without causing severe pain. Regardless, a single dose intramuscular analgesic is administered beforehand so as to minimize any possible pain while preventing the patient from shifting focal point of the calculus by inhaling deeply, i.e. to increase the rate of success. Depending on preferences of the physician and the patient, ESPB (erector spinae plane block) or intravenous sedation may be selected as well.
While the patient is attending the admission process at the admission office, our physician and technician calibrate the device for use. Right after receiving a dose of analgesic, the patient is brough to the ESWL unit on floor 1, where the procedure takes place, and positioned in accordance with the location of the targeted calculus. The calculus is visualized under fluoroscopy or ultrasonography and device is focused on the lithotripsy zone. At this point, the ultrasonography gel is applied on the relevant area of the body, which eliminates pockets of air between the lithotripter and the body for maximum effect. The ESWL procedure then starts with a “click” sound. The patient continues to hear this click in short intervals and mildly feels vibration. Focal point of the calculus is frequently checked and energy level is increased in a controlled manner. The amount of energy and number of waves are adjusted in accordance with the patient’s tolerance level as well as with hardness, location and fragmenting capacity of the calculus.

Once the procedure has been completed, x-ray imaging at the ESWL unit reveals the extent to which the calculus has been fragmented. The patient is duly informed and discharged to revisit 5-7 days later for a polyclinic follow-up with ultrasonography and x-ray images. 

Aside from the admission and preliminary preparation, an ESWL session lasts approximately 50-55 minutes.
  • Intrinsic features of each patient, properties of calculi and patients’ expectations are taken into account to create a ‘tailored treatment approach’.
  • Treatment is planned and carried out by physicians specialized in all aspects of treatment of calculi at Koç University Hospital. 
  • Thanks to our highly experienced team, combined therapies involving more than one surgical technique can be performed in the same session for the most successful outcome possible. 
  • The latest ESWL technology is available at our and utilized under guidance of the most recent literature in this field. 
  • Following treatment of your calculous condition, a metabolic evaluation (urine and blood tests, calculus analysis) is conducted, diet-liquid intake plans are made to prevent/delay recurrence, and specific medical treatments are administered. 
  • The ESWL procedure is performed by physicians who concentrate specifically on treatment of calculous diseases of the urinary system. 
  • Siemens Modularis Variostar electromagnetic lithotripters are utilized in this procedure. 
  • Thanks to this cutting-edge technology, ESWL is performed more comfortably and at higher success rates.

Clinical genetics

Clinical patient services are provided by three specialized physicians at the examination room located within the pediatric polyclinic and the genetic consultation room in the obstetrics polyclinic. Our team is highly experienced in diagnosis, prenatal diagnosis and follow-up of rare genetic syndromes with cognitive deficiency and congenital deformations. Patients and/or their family members are informed in detail about benefits of individual and family-specific genetic tests in cases of cancer and risky pregnancy. Results are duly conveyed to patients and family members so as to raise awareness about existing genetic risks, if any. 


Genetics laboratory

Comprehensive genetic tests are performed at our laboratory for the purpose of diagnosis prenatal and postnatal genetic diseases. The diagnostic laboratory of Genetic Diseases Diagnostic Center has been accredited for compliance to testing quality standards, and is equipped with all necessary technological facilities. The laboratory has its own divisions for conventional cytogenetics, molecular cytogenetics and molecular genetics. Each unit is led by a clinical laboratory supervisor with over 10 years of experience in their own fields. The result reporting interval is the same as large-scale university reference centers around Europe. 


Cytogenetics and molecular cytogenetics:Cytogenetics and molecular cytogenetics divisions are configured as separate spaces allocated to cell culture, cytogenetic analysis and in situ fluorescence procedures. Cytogenetic and molecular cytogenetic analyses can be performed on blood and various tissues/tissue cultures. They can also be carried out on cordocentesis, amniocentesis and chorionic villus biopsy (CVS) specimens for prenatal diagnosis. Up-to-date testing processes are conducted at the laboratory for cancer genetics. 

Molecular genetics:The molecular genetics division of the laboratory has DNA isolation, PCR and post-PCR rooms. In addition to essential basic infrastructure and equipment, the division includes NGS-based (next-gen sequencing) multi-output and micro-sequencing analysis platforms (Illumina MiSeq next-gen sequencing and Illumina Iscan micro-sequencing devices). The molecular genetics laboratory routinely conducts classical diagnostic test methods like Sanger sequencing, MLPA and q-PCR for deletion/duplication analyses as well as methylation analyses, triplet repeat fragmentation analysis for evaluation of dynamic mutation diseases and next-gen sequencing panels aimed at evaluating cancer predisposition, hereditary cardiac diseases and Mendelian hereditary diseases. 

Our department stands out as the only center in Turkey where molecular diagnosis of facioscapulohumeral dystrophy can be made. Used for this purpose, the Molecular Combing System was integrated to our laboratory in 2019.  


Bio-informatic stages of high-output sequencing and micro-sequencing analyses are carried out at our department. Variants are reviewed together with a bio-informatics expert and clinical genetics specialist, if necessary, which boosts diagnostic accuracy. Studies undertaken within this framework involve compilation of folders from raw data, arrangement and preparation for analysis. Genetic data obtained in this manner is thus utilized for diagnosis of recessive and X-specific inherited disease carriage and research of new genes associated with the disease.

Interventional Neuroradiology

Cerebral aneurysms

An aneurysm is ballooning that occurs in a weak spot of the brain’s arteries. Cerebral aneurysms might potentially burst at a fragile point, resulting in a type of intracranial hemorrhage known as subarachnoid hemorrhage, which is a severe and life-threatening medical condition. Approximately 35% of patients experiencing subarachnoid hemorrhage lose their lives. On the other hand, we are able to diagnose and endovascularly treat the majority of cerebral aneurysms before they burst and cause intracranial hemorrhage. It is essential to close the aneurysm in patients who have experienced an intracranial hemorrhage. Along with novel techniques devised within the past 20 years, endovascular treatment methods have become the primary option in treatment of aneurysms. 

Carotid stenosis

Carotid arteries are two of the 4 essential vessels supplying blood to the brain. The disease of atherosclerosis often impairs carotid arteries with stenosis and occlusions, which in turn prevent adequate blood from being supplied to the brain and might consequently cause palsy/stroke. Stenoses building up in carotid arteries lead to temporary ischemic attacks, which last less than 24 hours and subside on their own. Temporary ischemic attacks trigger symptoms like formication, numbing and weakness in legs and arms; speech disorder; difficulty making out words; lisping; sudden loss of vision in one eye; shifting in one half of the face and lips; and dizziness. These attacks are precursors of an impending permanent palsy attack. Medical treatment proves to be insufficient if the level of stenosis in a carotid artery is over 70 percent, in which case additional interventional treatment is required. Stenting and balloon angioplasty are reliable and effective methods in treatment of carotid stenosis. 

Arteriovenous malformations (AVM)

Arteriovenous malformation is a cerebrovascular condition where multiple vessels of abnormal morphology get tangled up. AVM causes high blood flow velocity inside that gradually causes vessel walls in the tangle to weaken. Over time, one of the vessels constituting the tangle might burst and result in intracranial hemorrhage. Overall, AVM is not accompanied with any complaint in 25% of cases and is incidentally diagnosed in imaging studies like MRI, which may originally be performed for other reasons. The other 75% of the patients will experience headache, epilepsy (seizures), numbing in arms and legs, weakness and speech difficulty. Endovascular treatment (embolization), open surgery and radiosurgery are the primary treatment methods for arteriovenous malformation. AVM treatment should be carried out by taking into account numerous factors and handled by a team of neurosurgery, interventional neuroradiology and radiosurgery specialists. Some patients may require combined therapies where two or even three different techniques are practiced consecutively. 

Arteriovenous fistula (AVF)

Arteriovenous fistula is a condition characterized with a direct connection that forms between an artery and vein. As a result, the high-pressure blood in an artery passes through a vein and leads to elevated venous pressure in the brain or spinal cord. The high pressure in the vein eventually tears the vein and could cause intracranial hemorrhage. In other cases where there is no intracranial hemorrhage, the high venous pressure prevents the brain and spinal cord from receiving sufficient blood, leading to complaints like weakness, speech disorder, inability to urinate and stroke. Arteriovenous fistulas of the brain and spinal cord are treated by means of endovascular methods. Some patients may require open surgery as well.

Interventional Radiology

Interventional radiology procedures are not surgeries. All procedures are performed by gaining access through a tiny needle hole and either in a radiology room or angiography room. They come with substantial advantages over surgical operations: 
  • General anesthesia is not required.
  • All treatments are performed through a thin needle.
  • No surgical scar remains on the body.
  • Patients are often able to receive their treatment and return home on the same day. 
  • Risks are far lower than those of surgery. 
  • Patients return to their daily routines far sooner. 

General anesthesia may still be required in interventional radiology procedures aimed at major conditions like cerebral aneurysm. Otherwise all procedures can be carried out under local anesthesia. In some cases, the patient may be given sedatives through the intravenous route. Sedation relieves patients who may grow concerned, excited or afraid even in some simple procedures like a needle biopsy. Patients are often kept under observation for 2-6 hours after each treatment and then allowed to return home afterwards. They can usually return to their normal routines within the same day or the next day. 

Neonatal Intensive Care

  • Neonatology
  • General pediatrics

Prematurity (early delivery)

Babies delivered before the expected term may be unable to sustain vital functions such as respiration, feeding and preservation of body temperature, which means they need to be supported by simulating circumstances similar to the womb. The necessary support is provided at our unit with the help of modern technological facilities like incubator, patient monitors, respirators, parenteral nutrition systems etc. 

Diseases specific to the neonatal period

Some diseases that are life-threatening or might result in permanent damage like jaundice, necrotizing enterocolitis, retinopathy of prematurity, patent ductus arteriosus, respiratory distress syndrome, intracranial hemorrhage etc. might be encountered during the neonatal period. Our unit adopts painstaking observation measures for prevention and early diagnosis and treatment of such conditions. Newborns’ examinations and investigations, including hearing and ophthalmological examinations, cranial USG, EEG, echocardiogram etc., are conducted in accordance with their screening programs.  

Congenital malformations, syndromes, metabolic/endocrine/genetic diseases etc.

Some structural disorders or diseases may be detectable right away, whereas others may manifest symptoms during the first days of life. If such disorders or diseases are identified or suspected, patients are evaluated in collaboration with medical genetics or other relevant departments in order to diagnose their conditions with special tests and screening procedures. 

Surgical diseases

Neonates who underwent pediatric, cardiovascular, plastic or otorhinolaryngological surgery are observed at our unit during the preoperative and postoperative periods. 

Infectious diseases

Infections are among the most prominent problems experienced at intensive care units, and unfortunately, rate of infection can never be reduced to zero. However, the risk may be mitigated substantially by employing strict measures. If necessary, this group of infants can be observed in rooms specifically designated to this purpose. 

Perinatal asphyxia

This is an incident where the baby might be deprived of oxygen due to various reasons and sustain damage to some organs, primarily the brain. To mitigate this damage as much as possible, whole-body therapeutic hypothermia is practiced at our unit. Long term monitoring under aEEG, a special format of regular EEG, and MRI imaging (under supervision of an anesthesiologist, if necessary) are conducted to determine the impact on the brain.

Refractive Surgery (Elimination of Dependency on Spectacles)

Refractive disorders occur depending on refractive capacity of the cornea and structure/anteroposterior length of the lens. There are 3 primary types of refractive disorders: Myopia, hypermetropia and astigmatism, which are also known as refraction errors. Refraction errors are mitigated with the help of optic products like spectacles and contact lenses, and can be corrected through refractive surgery, which includes laser applications and intraocular lens implantation. Based on examination and investigation findings, patients with refractive errors undergo the most suitable refractive surgery procedure. Refractive laser surgeries are performed at our department to eliminate dependency on spectacles. These include the flap-free wavefront-backed PRK and LASIK operation, which involves a flap. In cases where the use of a laser is not practical for correction of myopia, hypermetropia or astigmatism, intraocular lens (phakic) implantation is successfully performed as well. 

Cataract and Intraocular Lens Surgery

Currently the most recognized technique for cataract surgery around the world, suture-free phacoemulsification under drip anesthesia is performed at our department. In this procedure, the eye is anesthetized with drops instead of an injection. Cataract surgery is performed through a tiny incision measuring approximately 2 millimeters on the transparent layer, and an appropriate lens is performed in the ocular zone. The patient does not need to be hospitalized afterwards, and is bound to regain their former pre-cataract visual acuity. Ordinary and complex (high-risk) cataract surgeries are routinely performed at our clinic. Once the cataractous lens has been cleaned, a monofocal (far focus), multifocal (known commonly as ‘smart lens’; near, intermediate and far focus) toric (astigmatism correction) or next-gen monofocal (ring/glare reduction, far to intermediate focus) can be selected and implanted to the eye in accordance with the patient’s preferences and indications. Other procedures aimed at complex cases (such as pupilloplasty, iris repair, intraocular lens fixation to iris/sclera etc.) are successfully performed at our clinic too. 

Cornea and Ocular Surface Unit

Cornea is a transparent, dome-like anatomic structure positioned in front of the ocular globe. Cornea and the structures in its periphery are called the ocular surface. There is a lacrimal layer on it, which keeps the ocular surface smooth and damp and protects it from external factors. Diseases of cornea, conjunctiva and eyelids are addressed separately, and also collectively as ocular surface diseases. Ocular surface diseases like infections of eyelids and eyelash roots (blepharitis), ocular membrane (conjunctivitis) and corneal infections associated with bacteria, viruses, fungi and parasites (keratitis) as well as congenital and acquired structural disorders of cornea (e.g.: keratoconus, corneal edema, neurotrophic keratopathy etc.) are among the conditions in which our clinic is specialized.  

In addition to diagnostic procedures like biomicroscopic examination for diagnosis of corneal and ocular surface diseases, confocal microscopy, meibography, tear osmolarity test (TearLab) and clinical microbiology tests, medical and surgical treatment methods are successfully practiced. These treatments include medical therapy and punctum plug implantation for dry eyes; amniotic membrane cover and tarsorraphy for advanced ocular surface disorders; corneal collagen cross-linking, intrastromal corneal ring segment implantation (ICRS) and special contact lens applications for keratoconus; and cornea transplantation procedures (phototherapeutic, penetrating, deep frontal lamellar, Descemet’s membrane endothelial keratoplasty).

Our department also carries out numerous leading scientific studies in diagnosis and treatment of corneal and ocular surface diseases. 


Our retina unit is equipped with the facilities required for color fundus photography, fundus autofluorescence imaging, multicolor imaging, optic coherence tomography, fundus fluorescein angiography and indocyanine green angiography, which are all investigations aimed at diagnosis of all retinal diseases. Intraocular drug injections for age-related macular degeneration, which is also known as ‘yellow spot’ disease and currently the most prominent reason underlying loss of vision around the world, is successfully performed at our clinic. Differential diagnosis of various other conditions that are often mistaken for age-related yellow spot disease is also conducted without error thanks to our specialized physicians and advanced diagnostic technology. For treatment of diabetic retinopathy -a condition that develops secondary to diabetes- and retinal venous occlusion, we utilize argon laser photocoagulation and intraocular drug injection methods. Hereditary retinal conditions like night blindness (retinitis pigmentosa), cone dystrophy and Stargardt disease are routinely treated by means of PRP administration into the membrane.  

Furthermore, ‘vitrectomy’ and other surgical techniques are carried out to successfully treat other conditions requiring surgical intervention, including diabetic retinopathy, intraocular bleeding (vitreus hemorrhage), retinal detachment, macular hole and epiretinal membrane. 

We are also developing novel treatment options with a focus on various retinal diseases as part of the leading regenerative medicine studies conducted in collaboration with Koç University Laboratories.  

Ocular Immunology and Uveitis 

Uveitis is described as inflammation of the uveal tissue of eyes. It is condition that results from infections like herpes virus, toxoplasmosis, tuberculosis or syphilis or due to inflammation of the eyes secondary to other autoimmune conditions like rheumatoid arthritis, Behcet’s disease, ankylosing spondylitis and sarcoidosis. Sometimes, uveitis is not necessarily accompanied by another disease. Such cases are categorized as idiopathic. Uveitis cases are evaluated by specialized physicians, who carry out necessary diagnostic studies and draft a suitable treatment and follow-up plan at our unit. In addition to medical treatment of uveitis, ocular complications associated with uveitis are taken under control and essential surgical interventions are performed afterwards.

Ocular Hypertension (Glaucoma)

Glaucoma, i.e. ocular hypertension disease, is a chronic disease that is accompanied with optic nerve damage, often runs a subtle course of progression, and threatens public health. Patients presenting to our clinic with early or late-stage glaucoma go through diagnostic tests and receive medical or surgical treatment under the light of current medical literature. 
Applanation tonometer, Tono-Pen, non-contact tonometer or iCare tonometer are utilized to measure intraocular pressure. A computerized visual field test with different color adjustments is performed at our unit in order to identify visual field defects. Retinal nerve fiber layer is evaluated under optic coherence tomography (OCT) for the purpose of detecting optic nerve damage. Additionally, ultrasound Biomicroscopy is utilized in diagnosis of some specific subtypes of glaucoma. Thanks to all of these tests, glaucoma, a chronic disease, is diagnosed, treated and followed in a robust manner. 

Treatment options include drops for reducing intraocular pressure and a range of surgical procedures from laser iridotomy to trabeculoplasty, combine cataract and trabeculoplasty surgery, seton operations and Ahmed valve tube implantation. 

We are also conducting leading studies on diagnosis and treatment of glaucoma in collaboration with Koç University Laboratories.

Neuro-ophthalmology Unit

As can be inferred from the name, the neuro-ophthalmology unit is a subbranch concentrating on ophthalmologic conditions associated with the brain, which looks into ocular or visual field disorders, synchronization disorder of eye movements and abnormalities of the pupil that may accompany optic nerve or cerebral diseases. Ophthalmologists specialized in this field most often treat optic neuritis resulting from involvement of the optic nerve by multiple sclerosis, ischemic optic neuropathies or papilledema, which might be caused by increased intraocular pressure. Disorders associated with cranial tumors, myasthenia gravis, ocular muscle paresis, pupillary abnormalities and cancer (paraneoplastic syndromes) are included in the field of interest for this subbranch. 

To diagnose this group of diseases, color vision examination, pupillary examination, pharmacologic tests, computerized visual field test, color fundus photography, ocular ultrasound and optic nerve tomography are employed at the clinic. Eligible cases are also referred to the department of neurology for visual evoked potentials test (VEP). 

Interdisciplinary work is essential in treatment of neuro-ophthalmologic diseases. Therefore, treatment plans are drafted in collaboration with the departments of neurology, neurosurgery, internal medicine and radiology. 

Pediatric Ophthalmology and Strabismus Unit

Treated and followed in only a few medical centers in our country, retinopathy of prematurity (ROP) is a prevalent condition among premature infants. The specialized physicians at our polyclinic treat infants diagnosed with this condition, including those who are staying in incubators at the neonatal intensive care unit or present on outpatient basis. Treatment options for ROP include intravitreal drug injection and laser photocoagulation. Backed up modern surgical equipment, our experienced team practices medical and surgical treatment for pediatric cases of congenital cataract, strabismus and amblyopia (lazy eye) in addition to conducting routine eye checks for healthy children. Non-contact automatic refractometer measurements are carried among the pediatric population below 3 years of age. The Krimsky test -which employs prismatic glasses- and Worth 4-dot test are conducted in examinations for strabismus and amblyopia. The Titmus test for stereopsis is also available at our clinic. 

Oculoplastic Surgery (Ocular Cosmetic Surgery) and Orbital Surgery

Our oculoplastic and orbital surgery unit performs interventions and operations aimed at treatment of eyelid diseases, lacrimal canal disorders, orbital implant problems, thyroid orbitopathy, eyelid and orbital tumors as well as all cosmetic procedures around the eye. Among the polyclinic services provided by the oculoplastic surgery unit are biomicroscopic examination, Hertel exophthalmometer, Humphrey visual field test and Ishihara color vision test. Punctum plug and perforated punctum plug applications are carried out to treat dry eyes and epiphora as well. Treatment of congenital or acquired ptosis, trichiasis, entropion and ectropion pathologies of eyelids are treated with modern surgical techniques. Endonasal or external dacryocystorhinostomy are surgical procedures aimed at lacrimal system disorders. Thyroid orbitopathy cases are diagnosed and followed in coordination with the department of Endocrinology. We provide medical treatment, orbital decompression surgery and radioactive iodine therapy options in accordance with patient preferences and clinical indications. On the cosmetic side, upper and lower blepharoplasty operations, reposition of fat pads and Botox injections can be performed to improve the cosmetic appearance of the areas around the eyes.  

Ocular Oncology Unit

Ocular Oncology is the branch that focuses on tumors afflicting the eyes or their periphery. Differential diagnosis of all types of ocular oncology cases is rendered by use of advanced radiologic, medical and ophthalmic instruments. Our unit is well capable of treating all tumors that may be found in or around the eyes, including some severe cases like malignant melanoma and retinoblastoma. Treatment of ocular tumors at our clinic includes radiotherapy, plaque radiotherapy, cyber knife, chemotherapy and surgical excision. 

Contact Lens Unit

Contact lenses are widely used in correction of refractory disorders. Manufacturing technologies in this field have followed in the footsteps of advancements in biotechnology. Currently, soft contact lenses provide an alternative to spectacles in numerous conditions. Contact lens trial sets by a number of different contact lens manufacturers, all approved by the Ministry of Health, are available at our contact lens unit. These allow each patient to try on different options for a precise prescription. It is possible for new users with no prior history of contact lens use to find out whether or not their eyes are suitable, whereas anterior and posterior surfaces of long-time contact lens users can be evaluated through corneal topography at our unit. Schirmer test and non-invasive tear film breakup time tests are other investigations specifically designed to determine tear quantity and functions. 

Aside from contact lenses suitable for myopia (minus refractive error) and hypermetropia (positive refractive error), toric (astigmatic) contact lenses can be tried on at our polyclinics, where satisfactory results are attained for refractive error margins up to -3.0 diopters. As an alternative to multifocal glasses and intraocular lenses designed for both near and far vision, we offer multifocal contact lenses that enable clear vision in close, intermediate and far distances.  

On top of the various usage cases described above, contact lenses can be utilized almost like a ‘band-aid’ for therapeutic purposes in corneal diseases or following refractive surgeries. If the corneal hue has changed because of underlying ocular conditions, special colored contact lenses are also a prosthetic option for matching the color of the intact eye for a satisfactory cosmetic appearance.

Low Vision Rehabilitation Unit

Patients who experience advanced loss of vision due to conditions such as retinitis pigmentosa (night blindness), cone dystrophy, Stargardt disease, age-related macular degeneration (yellow spot disease), diabetic retinopathy, glaucoma and retinopathy of prematurity are assisted at this unit to restore adequate vision by use of special spectacles, devices and methods of rehabilitation.

All traumas relevant to these parts of the body and all pediatric musculoskeletal diseases are addressed at our department too. Furthermore, the department of Orthopedics and Traumatology collaborates with other branches in treatment and diagnosis of foot problems resulting from vascular occlusion, infection and chronic injury.
  • Orthopedics and Traumatology (principal branch)
  • Hand Surgery and Microsurgery (side branch)


Cytology and surgical specimens are analyzed for pathology by a team of specialized pathologists equipped with cutting-edge laboratory infrastructure at our laboratory. Additionally, the team conducts immunohistochemical and molecular studies, which are of predictive significance for determining immunotherapy options or target-specific therapies for cancer patients.  

Our advanced immunohistochemistry laboratory is able to conduct studies using nearly 300 antibodies, while routine tests of our department include immunofluorescence and in-situ hybridization as well.

The molecular pathology laboratory, on the other hand, routinely performs real-time PCR, pyrosequencing and next-gen sequencing tests.
  • Electron Microscopy

Comprehensive Pediatric Diabetes Program 

Although diabetes is primarily known as an adult disease, it is also encountered among children, starting from early ages. Type 1 diabetes among children occurs due to permanent deficiency of the insulin hormone, which regulates blood glucose levels. Therefore, once diagnosed, diabetic children are required to measure blood glucose levels at least 4-6 times a day and receive insulin hormone externally by means of injection or an insulin pump accordingly. 

Diabetic training is as important as insulin intake and treatment in terms of long-term follow-up and leading a healthy life. Diabetes has recently become not so much of a burden for children and parents after the advent of “Flexible Diabetes Therapy”, which is essentially based on carbohydrate counting. Training also plays an important role in alleviating level of concern for diabetic children and their parents. While diagnosed children are provided with basic information after being admitted to a hospital, diabetic children camps also offer quite an effective means of training by enabling children to meet physicians, nurses, dietitians and other experienced diabetic peers. 

All of these efforts should also be reinforced with support in the school setting, resilience building to cope with diabetes, early diagnosis of possible mental problems, a diabetic-friendly life and guidance on the route to adult life.

The Comprehensive Pediatric Diabetes Program includes the following:
  • Physician consultation for 45 minutes at minimum for type 1 diabetes patients presenting for the first time, who are then given a written report on the physician’s recommendations/glycemic targets. 
  • Basic training updates and advanced training (consultations once with a nurse, 3 times with a dietitian and once with a psychologist - training on carbohydrate, protein and fat count as well as exercise management).
  • Constant communication with the diabetes team.
  • Dietitian consultation during at least one of every two visits. 
  • Use of Continuous Glucose Monitoring Systems (sensors) for cases where it is possible. 
  • Use of insulin pump for cases where it is possible. 
  • “First Visit Package” and “Insulin Pump Therapy Package” aimed at facilitating access to our programs and payment. 


Insulin Pump Therapy and Advanced Technologies Program 

Treatment of type 1 diabetes has recently use of insulin pumps as well as introduction of some significant technologic advancements. Insulin therapy with “smart insulin pumps” renders treatment more physiological, whereas continuous blood glucose measurement systems are about to replace the conventional fingertip puncture. Not so long ago, these advancements have also enabled routine use of systems such as “artificial pancreas” and “bionic pancreas”, which allow automatic administration of insulin and blood glucose measurements. Insulin pump therapy and sensor products that are available in our country are utilized at our department. Currently, 20% of the children followed at Koç University Hospital with the diagnosis type 1 diabetes use insulin pumps, and 46% use continuous glucose monitoring systems. 

As the Pediatric Diabetes team of Koç University, we do realize that insulin pump alone will not make a substantial contribution to treatment. That is why we concentrate on comprehensive diabetes training, primarily carbohydrate counting. Upon reaching a mutual agreement with diagnosed children/adolescents, parents and team members, we decide on fitting patients with pumps and make sure that they are trained in and follow training on carbohydrate counting/management. Insulin pump therapy consists of a 3-day process and consequent follow-ups.

  • Review of settings. 

Diabetic Children’s Parents Solidarity and Guidance (Mentorship) Program

The diagnosis process of type 1 diabetic children, management of the consequent process, parents’ approach and perception of their children’s condition and social support are of utmost importance. Availability of people healthcare personnel as well as other parents who can provide support and share their own experiences can positively influence the mood of parents and increase their level of resilience. 

The Diabetic Children’s Parents Solidarity and Guidance (Mentorship) Program aims to facilitate access to correct knowledge, train experienced parents practicing good management as mentors, and closely support other type 1 diabetic patients and their parents. Below are the objectives of this program: 
  • Creating an environment where type 1 diabetic children and their parents can share their experiences, questions and knowledge alongside experts sharing their scientific data with the help of the website www.arkadasimdiyabet.com
  • Training volunteering parents who can act as mentors; 
  • Allocating a certain number of parents to mentors (by taking into account specific features such as having diagnosed children of the same age group and residing in close proximity to each other), who will then assist these parents in matters such as management of diabetes and social support (immediately as needed); 
  • Visiting recently diagnosed type 1 diabetic children and their parents at the hospital and supporting them; 
  • Organizing activities where parents and children gather together and promoting sharing among them; 
  • Providing voluntary aid to those families whose may be in need of financial support. 


My Friend Diabetes İznik Camp

“My Friend Diabetes” camps have been set up in İznik since 1997 and Diyarbakır since 2011 (and commonly in İznik since 2016) in order to provide a setting that can help improve training and restore health among diabetic children. While basic topics are covered in the form of class lessons, groupwork and experience sharing activities are held at the camp. Children are grouped in accordance with age groups, where they are trained and share their experiences in topics like “general approach to diabetes treatment”, “being at peace and coping with diabetes”, “type 1 diabetes and exercise”, “insulin pump therapy and new technologies”, “carbohydrate, protein and fat counting”, “adjusting insulin dosage” and “hyperglycemia and ketonemia management at home”. Various sports -primarily swimming-, entertainment and art activities are also made available outside the training hours. A team of pediatric endocrinologists, pediatric health and mental health specialists, dietitians, diabetes nurses, psychologists, activity leaders and students from departments of medicine, dietetics and nursing works on the camp grounds 24 hours a day under leadership of at least 2 faculty members. Experienced older brothers and sisters also share every moment of the day with children as “role models”.  
You can find out more on the My Friend Diabetes İznik Camp page.

My Friend Diabetes Parents’ Camp

Parents sending their children to these camps have often mentioned that they would also like to attend such a camp, where they get to meet other parents or diabetic children and interact with them. To answer this call and complete the “value creation chain” as part of our “Comprehensive Pediatric Diabetes Program”, we have been organizing the “My Friend Diabetes” parents’ camp since 2018. This is a camp for diabetic children as well as parents and non-diabetic siblings.  
You can find out more on the My Friend Diabetes Parents’ Camp page.

Diabetes at School Program

Diabetic children spend the majority of an ordinary day (8-10 hours a day) under supervision of school staff. The lack of glycemic control within this period of time has a negative impact on management of diabetes. Unless they receive proper training, school staff -mainly teachers- may experience difficulty in terms of responding to requirements of diabetes management and ensuring optimal blood glucose control. Furthermore, regardless of age groups and level of self-sufficiency, type 1 diabetic children are in need of support during their time at school, which means that the supervision of school staff is of utmost importance. Because there is no school nurse at many schools, monitoring blood glucose levels and administering insulin doses are a responsibility assumed by parents and school personnel. We have been practicing the Diabetes at School program since 2010 in our country and conducting various activities within this framework. 
As the Pediatric Diabetes team of Koç University, we conduct the “Emergency Diabetes Care Program at School” on the last Saturday of each month as part of the overall program. So far, 60 teachers and nurses have taken part in these courses since October 2018. 

Diabetes Training Program

Our department has launched an online training program named “Diapedia” for the purpose of training the diabetic children under our supervision and their parents while also supporting training of other diabetic children and their parents around the country. All activities conducted within the framework of this program are posted on the Vehbi Koç Foundation Healthcare Institution live broadcast and video portal, where recorded videos can be viewed at any time. 

Our team has also recently published the course books “Diary of the Diabetic Child”, “Time to Befriend Diabetes” and “Learning to Live with Diabetes”. These books and other presentations are available on the My Friend Diabetes website.


My Friend Diabetes Basketball Show and Run 

One of the common issues encountered by diabetic children and youngsters is that the society does not really know much about type 1 diabetes. Most people meeting a type 1 diabetic child for the first time typically think that they cannot live a normal life, get married and have children like everyone else or carry on performing any sportive activity they may have taken up. What is more, some business owners and HR departments tend to be reluctant to employ type 1 diabetic youngsters. Because of all of these realities, some diabetic children cannot help but think that people will treat them differently after finding out about them being diabetic.

However, it is currently possible for diabetic children and youngsters to live a completely normal and successful life by receiving the appropriate treatment and do everything that their peers can by “Befriending Diabetes”. Basketballer Alper Saruhan and marathon runner Gürkan Açıkgöz are some of the successful diabetic athletes, to name a few. Alper Saruhan notes that diabetic children deserve the title of ‘survivor’ the most rather than the contestants on the television. He states that his life is an example that one can succeed as a diabetic athlete, underlining that diabetes is not an obstacle that prevents one from achieving their goals and all difficulties can be overcome by befriending diabetes.

To emphasize the fact that type 1 is not an obstacle for sportive activities and that type 1 diabetes patients can make a difference in their own lives by means of sports, the Turkish Basketball Federation’s Association of Coaches has been arranging show matches between famous basketballers and type 1 diabetic basketball players since 2017. Also since 2017, the Koç Sports Collective has been organizing the My Friend Diabetes Run in the Bağlarbaşı grove. 

Comprehensive Obesity Program

Obesity and related disease -particularly diabetes- have turned into the most urgent public health issue of our time. Mortality rates associated with obesity have even surpassed that of hunger in some parts of the world such as the USA. Recent research has also shown that over 30% of adults and 20% of children in our country are overweight and obese.

According to findings of the “Childhood Obesity Research” among second-grade children, which was conducted on the basis of the methodology proposed by WHO, prevalence of obesity is 8.4 and prevalence of overweight, which signals risk of obesity, is 14.3 in this age group. It has also been found out that prevalence of overweight is three times higher in urban areas than in rural regions. A similar difference exists between İstanbul/West and East/Southeast. This set of data clearly displays the extent to which lifestyle and dietary habits determine the increased risk of obesity for children. Children living in cities and in western regions overall encounter food items that instigate a sense of enjoyment upon consumption and create a lifelong habit more often, which results in them gaining weight early on. We all know how junk food is “readily available” everywhere, particularly supermarkets. It is also known that these products are usually described as cheap and “safe” -which is not entirely true; they may be safe, but also they are unhealthy-, and marketed as favorable items often by means of cartoon characters. Those children who are exposed to such advertisements consume 40 percent more stick crackers than those wo are not. This is all closely related to the high and rapidly absorbed sugar content found in “junk food” and processed products, which in turn causes “food addiction”.  

Obesity is a complex problem that respectively leads to an increase in the overweight population in a society, prevalence of obesity and obesity-associated diseases like type 2 diabetes, shortened life expectancy due to these diseases and eventually epigenetic accumulation carried over from one generation to the other. From this point of view, it seems that protecting children from the risk of obesity and treating obese individuals constitute the most notable strategy for maintaining children’s and adults’ health, i.e. public health as a whole.

We are glad to serve obese children with 27 years of experience and the latest technology at our disposal as the Pediatric Endocrinology team of Koç University Hospital. Below are the services our team offers:

  • Crossmatched kidney transplantation
  • Crossmatched liver transplantation
  • Domino liver transplantation

For the purpose of achieving the highest success rate, our organ transplantation surgeons have combined their collective specializations in laparoscopic and robotic techniques in the field of kidney transplantation. 

Available only in few centers around the world, robotic kidney transplantation is performed by the experienced organ transplantation team of Koç University Hospital. This is an operation were the donor’s kidney is placed in the recipient’s body through a small 5 mm periumbilical incision. The rest of the procedure is performed by use of the da Vinci XI robotic surgery system. Surgeons control the robotic arm via a computer interface and conclude the kidney transplantation procedure by means of surgical instruments introduced into the abdomen through small incisions. 

Not only is robotic kidney transplantation cosmetically far superior to open surgery, but it also ensures that postoperative pain is mitigated and patients can return to their daily routines sooner.

On top of all the advantages of robotic kidney transplantation, the Organ Transplantation Center of Koç University Hospital offers the most up-to-date equipment and practices for reliable minimally invasive operations on end-stage renal failure patients.

This is a test where pulmonary functions are measured with a device called spirometer. When necessary, a short-acting bronchodilator is inhaled to measure the level of obstruction in the airway and response to the bronchodilator (reversibility). There may be some drugs that your physician may ask you to discontinue prior to starting the reversibility test. This test is used for the purposes of diagnosing specific respiratory conditions like asthma and chronic obstructive pulmonary disease, and also for following up on response to treatment. This respiratory function test can be performed during the working hours without having to schedule an appointment beforehand. 

Methacholine Bronchial Provocation Test

This test is performed to detect airway hypersensitivity among individuals, whose conditions suggest asthma, yet there is no respiratory function test finding supportive of this diagnosis. Some medications may need to be discontinued. Make sue that you consult your physician prior to the provocation test in this regard. The methacholine bronchial provocation test is performed after scheduling an appointment in advance.

Diffusing Capacity of Lung for Carbon Monoxide (DLCO Test)

DLCO is a test that assesses gas exchange in lungs. It is primarily practiced to diagnose and follow up on some respiratory conditions like interstitial lung disease, and also as a means of preoperative evaluation. A small amount of (0.3%) CO is inhaled during this test to calculate the lungs’ diffusing capacity. Stopping smoking 24 hours in advance is recommended, as it would otherwise increase the presence of CO in alveoli. A blood count may be requested before the test so as to identify the patient’s current hemoglobin level. DLCO test can be performed during the working hours without having to schedule an appointment beforehand.

Pulmonary Volume Measurement by Body Plethysmography

This is a test method for evaluation of lung volumes. Thanks to use of advanced devices, it can be performed within a brief period of time during normal respiration. This test requires scheduling an appointment in advance. 

Intrathoracic Pressure Measurement (MIP, MEP)

This test is performed in case there is a suspected weakness of respiratory muscles or for the purpose of diagnosing and following up on muscular diseases. Maximum inspiration pressure (MIP) is used as an indicator of inspiratory muscle strength and maximum expiration pressure (MEP) as an indicator of strength in abdominal and other expiratory muscles. Intrathoracic pressure measurements can be conducted during working hours without scheduling an appointment beforehand. 

Six-minute Walk Test

A very simple way of evaluating cardiopulmonary and functional capacity, this test displays efficiency of current treatment and prognosis. It basically requires the patient to walk as long as they can on a predetermined path within six minutes without utilizing any specific equipment. Prior to starting and after completion of the test, blood pressure, fingertip oxygen saturation, heart rate and dyspnea parameters are monitored. If deemed necessary, the patient walks under oxygen support. Data collected by the end of the test are compiled into a report. The six-minute walk test can be conducted during working hours without scheduling an appointment beforehand.  

Cardiopulmonary Exercise Test (VO2 Max test)

This test, which enables differential diagnosis of dyspnea and preoperative evaluation of pulmonary and cardiac capacity, is performed on a stationary bike and under standard exercise protocols. It can be required for differential diagnosis of pulmonary diseases, in cases of vascular diseases and their follow-up (pulmonary arterial hypertension), cardiac diseases, muscle diseases, preoperative evaluation and evaluation for incapacity. 

Specific preparations should be made for this test. One is recommended to wear comfortable clothing, avoid smoking and caffeinated beverages, and start fasting two hours in advance. Bringing along all previous respiratory function tests, chest x-rays, tomography scans, lab results, consultations notes and investigation results like ECG and echocardiogram is also recommended. If you are on an inhaler, you should take your dose on time before arriving for the test. Contact your physician and our laboratory, if you are on a beta blocker or calcium channel blocker (heart rate regulators). This test requires an appointment. 

Exhaled Nitric Oxide (FENO) Measurement

FENO is a test procedure that measures non-microbial inflammation in the airways. FENO may be used for COPD and asthma patients and also patients presenting with chronic coughing. It is a simple measurement made by performing a 10-12-second exhalation maneuver. FENO measurement can be conducted during working hours without scheduling an appointment beforehand.
In addition to performing routine laboratory services, our laboratory trains medical faculty students and assistants. 
Respiratory function training courses are also organized in regular intervals prior to and after graduation periods for pulmonology specialists, assistants and laboratory technicians.

Radiation Oncology

The science of radiotherapy consists of planned and controlled use of ionizing beams in regional and predetermined doses. As a treatment method employed in treatment of at least one out of every two cancer patients, radiotherapy is performed for curative, adjuvant, palliative and prophylactic purposes. 

Radiation is produced by LINAC, linear acceleration, devices. Electrons are made to collide with a metal barrier to produce strong X rays called photons. Over a portal capable of moving 360 degrees, photon beams are conducted to the patient on the therapy pad. Each application of radiation is called a ‘fraction’.   

While radiotherapy ensures maximum impact on the tumor, it also aims to preserve healthy tissues around the tumor. Therefore, it requires careful planning, where the first step is simulation. In this process, the immobilization devices that are aimed at keeping the patient stable during treatment are tested. Tomography images are also obtained in the meantime. It may essentially be described as a rehearsal to radiotherapy. Data collected from the simulator allows radiation oncologists to calculate dosage prior to starting treatment.
Radiotherapy is one of the most significant approaches employed in treatment of various diseases, primarily cancer. More than half of all cancer patients receive chemotherapy. Concurrent chemotherapy and radiotherapy are preferred as a reliable and effective route of treatment in some cases.  

It is often chosen as the initial treatment approach especially in cases of lung, prostate, skin, head-neck cancers, early-stage Hodgkin’s disease, non-Hodgkin’s lymphoma and some tumors like cervical cancer. It is also widely used following surgical intervention in breast, endometrium, testis, bladder, thyroid, pancreas and brain cancers.  

Neoadjuvant radiotherapy is quite common in rectum and soft tissue cancers as well.

Pediatric cancer cases are evaluated individually in line with a multidisciplinary approach and guidelines.
A patient receiving radiotherapy may be treated at doses ranging between 20 to 78 Gy (1 Gy = 1 joule of energy absorbed per 1 kg of tissue) in accordance with the diagnosis, staging and purpose. The fact that the x-ray dosage a person is exposed to in a modern mammography device is approximately 1 per 10 thousand of 1 Gy could be a good indicator of the scope of radiotherapy. The total radiation dose is usually delivered in small doses over the course of 5 days in a week.
Physicians, radiotherapy technicians and patient relatives need to stay out of the room during radiotherapy in order to avoid exposure to radiation. Even though the patient is alone in the treatment room, they can be viewed on a monitor located out of the room. An audio system makes it possible to communicate as well.
A patient does not experience any kind of pain while radiation is being delivered to the target. There is actually no physical discomfort aside from mild irritations that may be experienced during brachytherapy practices. Furthermore, any pain that may be secondary to side effects can be communicated to the supervising physician throughout the term of treatment to receive necessary medical support.
Possible side effects of radiotherapy vary in accordance with numerous factors. Our physicians explain possible side effects that might occur during or after treatment to each patient. The majority of such side effects are entirely temporary and subside after treatment. It should also be noted that mitigating medication can be used for all side effects. In this regard, side effects should be conceived as temporary issues experienced almost by everyone, not at all as an indication of adverse course of treatment or disease.

Healthy cells that are within the target area radiotherapy are influenced by treatment too. Furthermore, the actual location and width of the treatment site matters. Side effects tend to be more frequent in wider areas. Daily doses, total doses and medication taken at the same time may modify side effects. Profile of side effects is directly relevant to performance and age status as well as to choice and quality of radiotherapy.   

Side effects on the skin occur in direct proportion to dosage increases and at later stages of treatment. Likewise, likelihood of side effect is higher in thin or creasing tissues where adequate hygiene and aeration may be difficult, such as the armpits, neck, anus and mouth. Initially appearing in the form of mild redness similar to sunburn, these may turn into purulent open wounds. Radiotherapy on the head and neck may impact the teeth, rendering them more prone to decay. This is why regular dentist checks are essential in these cases. As intraoral tissues are more sensitive to radiation, they may form oral sores. This also requires proper oral care. Other common side effects are drying in the mouth and difficulty swallowing because of lower salivary production. 

The patient’s sense of taste might become disrupted and skin sores could emerge during radiotherapy on the neck. Patients are advised to avoid alcohol and smoking while receiving radiotherapy because of their irritant effects. Impacts associated with lower appetite, voice changes, hair loss, difficulty swallowing in radiotherapy applications on the chest, vomiting, nausea, malaise, fatigue, dyspnea and dry coughs can be listed as the most common side effects. Diarrhea is also quite common with radiotherapy targeting the stomach and upper/lower abdomen. Gastric cramps and bloating may be accompanied with nausea, vomiting, low appetite, weight loss and painful urination.
Radiation oncologists draws up a treatment plan specifying the total days of treatment, number of sessions and radiation dose. They are also responsible for detecting and addressing medical problems that could occur during the course of treatment.
Taking into consideration the radiobiological characteristics of healthy and cancerous cells, high-dose radiotherapy is often performed in numerous sessions rather than at once. While this may change depending on the diagnosis, a period of 4 to 8 weeks on average is necessary for treatment. Spreading the process over time in this manner allows the body to dispose of the effects of radiation.


Our specialized physicians of internal medicine and rheumatology closely collaborate with the departments of physical medicine and orthopedics in order to manage the diagnostic and treatment processes of our patients as optimally as possible.
Musculoskeletal pain, deformation or difficulties are among the most prominent chief complaints presented. Pain in the lower back and joints of the hands and feet are also frequently reported to our department. 
Because numerous other systems may be involved in inflammatory rheumatic diseases, findings might vary quite a bit. 

Among others, fever, weight loss, skin eruptions, edema in extremities, weakness, recurrent abdominal pain and recurrent oral sores could be signs of rheumatic conditions as well.

Smoking Cessation Polyclinic

Nicotine is a highly potent psychological stimulant, so much that it is even more powerful than heroin, cocaine and alcohol when it comes to developing addiction. One out of every 3 people who try smoking for the first time becomes addicted.
Once you start smoking, the nicotine that is absorbed through the cheeks reaches the brain within approximately 10 seconds and causes secretion of some hormones by stimulating the center that is also typically stimulated by substances like heroin and cocaine. These hormones give rise to reward-like sensations like enhanced enjoyment, relaxation and boosted concentration, which in turn further increase the craving for nicotine. As your tolerance to these effects builds up over time, the number of cigarettes you smoke increases gradually. At this point, your body has to take in this substance, even if it does not need it. It can be difficult to manage on your own deprivation-induced feelings such as short temper, tension, disrupted concentration, increased appetite and depression.
Receiving assistance from our Smoking Cessation Polyclinic makes it easier to overcome these impacts.
Within 20 minutes after quitting smoking, your heart rate and blood pressure normalize. Risk of cardiac arrest decreases on day 1. Senses of taste and smell improve 2 days later. By the time it has been 2 weeks, your blood circulation gets regulated. Three months later, pulmonary functions start improving as well. Risks of cardiac disease and lung cancer decrease by half by the end of 1 year and 10 years, respectively. After 15 years, the risk of cardiac disease becomes equal to that of non-smokers.
Deprivation-specific complaints are most prominent during the initial 3 weeks. The most common symptoms of deprivation are restlessness, short temper, sleeplessness and concentration disorder. Two out of every 3 people who quit experience these symptoms. Support offered by the smoking cessation polyclinic (consultancy, nicotine replacement therapy and medical treatment) mitigates these complaints and improves the level of comfort during the process. Quitting thus becomes easier for you. 

It is quite normal for you to experience difficulties while you are quitting smoking. Please do not despair and keep trying. You can consult our “Smoking Cessation Polyclinic” for assistance with regard to difficulties encountered.
E-cigarettes and IQOS products, which heat tobacco instead of burning it, are among the top marketing items and the most recent products of the tobacco industry that primarily target the young population. These products are typically introduced as “less harmful” for the purpose of resuming smoking addiction by replacing tobacco products, which have been proven to have harmful impacts on health. However, these products should not be considered as alternatives for quitting smoking. It should be noted that e-cigarettes also contain carcinogenic and volatile organic components, and cause addiction by imitating the visual aspect and behavior of smoking.

Basic life support training is also offered and updated annually. In addition to mandatory training courses specific to each department, nursing staff members attend inhouse as well as external training as needed. 

The Nursing Directorate of Koç University Hospital, as part of the Vehbi Koç Foundation Healthcare Institutions, collaborates with Koç University School of Nursing, SANERC (Semahat Arsel Nursing Education and Research Center) and RMK AIMES (Rahmi Koç Advanced Interventional Medical Education and Simulation Center) in various fields. 

Each year, we jointly organize a Nursing Week seminar, a much-anticipated annual event that contributes to the profession of nursing and invites prominent names from national and international circles.
The “İstanbul Intensive Care Nursing Days” is another notable event that takes place biannually.
Nursing in a modern sense started in Turkey in the wake of the World War I. Admiral Bristol Nursing School, a significant pillar of nursing education, became the first school in Turkey to train nurses. The sustained success and constant improvement in the field of nursing education and healthcare that spurted after foundation of Admiral Bristol Nursing School on May 20th, 1920, and then Admiral Bristol Hospital on August 20th, 1920, was channeled by Vehbi Koç Foundation Healthcare Institutions into the foundations of Koç University School of Medicine and Koç University School of Nursing.  

At the time Admiral Bristol Nursing School was founded (1920-1999), the total term of education was 2 years and 6 months. The term was extended to 3 years in 1929 and then to 4 years in 1957. Nursing education at Koç University started off with a Vocational School of Healthcare Services in 1998. The Nursing College was established in 2005, followed with the Nursing School in 2016. As the first nursing school of Turkey, the institution raised leading nurses and set an example for other nursing schools to be founded over time. Esteemed Esma Deniz, one of the first 5 graduates of Admiral Bristol Nursing School in the year 1923, went on to found the Turkish Nurses Association in 1943, where she served as the Chair for 19 years and had the association acknowledged as an active member of the International Council of Nurses in 1949. Following in these footsteps, the Turkish Intensive Care Nurses Association was founded in 1992. Nurses of Vehbi Koç Foundation Healthcare Institutions have always been proud of Esma Deniz, forever an exemplary nurse and unyielding defender of women’s rights. 

Contributions of Vehbi Koç Foundation to the profession of nursing started after launch of the Nursing Fund in 1974. The Nursing fund has constantly contributed to education of nurses by means of conferences and seminars as well as publications and course books. So far, over 2000 nurses have been granted scholarships through the fund. Recognizing the essential value added by robust nursing education to a hospital’s quality of service, Vehbi Koç Foundation has supported efforts in the field of nursing at all times. Under the umbrella of the foundation, SANERC (Semahat Arsel Nursing Education and Research Center) delivered the first Intensive Care Nursing Course approved by the Ministry of Health. SANERC has been supporting nurses with national and international training courses, education events, symposiums and conventions since 1992 as well. 
After completion of preparations, Koç University Hospital started admitting patients in September 2014. Our Nursing Services Director, a member of the Admiral Bristol school, and the highly experienced leaders at American Hospital have been marching forward on our journey since the foundation. With an ever expanding staff of nurses and training and administration teams, the Directorate of Nursing Services has been promoting superior patient care in line with the mission and vision of Koç University Research and Education Hospital, and attained a privileged position in the field by training valuable students and leading research activities. 

Honorable Mrs. Semahat Arsel, Chair of the Vehbi Koç Foundation Board of Directors, has always contributed and continues to contribute to the development and empowerment of the nursing profession. As nurses of Koç University, we are infinitely grateful to the Koç Family and Mrs. Semahat Arsel.
