Established in 2000, the JCI, NABH accredited hospital is located in Istanbul, Turkey and operates 252 beds, with modern surgical oncology, urology, vascular surgery, diagnostic imaging, minimally invasive, and critical-care infrastructure.

Retroperitoneum Surgery can provide an important treatment option for appropriately selected patients with localized or complex diseases affecting the retroperitoneal space. Treatment planning considers the underlying diagnosis, size and location of the lesion, involvement of surrounding organs or blood vessels, previous abdominal surgery, and overall health. A multidisciplinary assessment helps determine whether surgery is appropriate and whether open, laparoscopic, or robotic-assisted techniques may be suitable for the individual patient.
