About the hospital

Koç University Hospital (Koç Üniversitesi Hastanesi) is the hospital of the Koç University School of Medicine in Istanbul. It has treated patients since September 2014 as a teaching and research hospital, so care and the training of medical students and residents happen in the same building. It was founded by the Vehbi Koç Foundation (Vehbi Koç Vakfı), and Koç University itself is a non-profit foundation university. The Turkish Ministry of Health lists it as a foundation university hospital.

The hospital belongs to the Koç Healthcare group but is a separate institution with its own building and departments. It ranked 1st among hospitals in Turkey in the Newsweek and Statista World's Best Hospitals 2026 ranking. Since 2025 its oncology service has been accredited as an ESMO Designated Centre of Integrated Oncology and Palliative Care (current recognition period 2026–2028), and since 2024 the hospital has been a member of the Mayo Clinic Care Network (a collaboration network membership, not an accreditation and not a Mayo Clinic branch).

Key centres

Comprehensive Cancer Program. Treatment decisions are made by a tumour board — a case conference of doctors from different specialties. The hospital states that its radiation oncology department works in collaboration with the MD Anderson radiation oncology centre. Techniques include IMRT and VMAT (intensity-modulated and volumetric arc radiotherapy), stereotactic radiosurgery (SRS) and stereotactic body radiotherapy (SBRT).

Bone marrow transplantation. There are two separate units, one for adults and one for children. They perform autologous transplants (the patient's own stem cells) and allogeneic transplants (donor cells).

Prof. Dr. Münci Kalayoğlu Organ Transplant Center transplants livers, kidneys and pancreases. Liver transplants include living donor transplants, with the donor's part of the liver removed laparoscopically, through small incisions. Kidney transplants are also performed robotically with the da Vinci Xi system.

ARIES (Advanced Robotic, Invasive Endoscopic Surgery Center) handles robotic and endoscopic surgery. According to the hospital, this includes robotic prostatectomy (removal of the prostate), nephrectomy (removal of a kidney) and cystectomy (removal of the bladder).

Radiosurgery Center opened in 2017. Radiosurgery here is performed on the Leksell Gamma Knife Icon (Elekta).

Cardiac surgery covers beating-heart coronary bypass, valve repair and replacement, and aortic surgery for aneurysm and dissection. Paediatric cardiac surgery is a separate service.

Orthopaedics includes a spine centre (scoliosis surgery), paediatric orthopaedics for cerebral palsy and hip dysplasia, and hand surgery with microsurgery.

Equipment

• Leksell Gamma Knife Icon (Elekta) — for radiosurgery.

• Linear accelerator — radiotherapy, SRS and SBRT.

• da Vinci Xi — robotic surgery, including kidney transplantation.

• O-arm — intraoperative imaging: in neurosurgery and spine surgery, implant position is checked during the operation itself.
