About
Nihat Karakoyunlu is a prominent urologic surgeon and researcher whose work centers on optimizing surgical outcomes in nephron-sparing surgery and robotic prostatectomy. His major contributions lie in standardizing the assessment of partial nephrectomy techniques through the Surface-Intermediate-Base (SIB) margin score, a framework he helped pioneer in a large international consortium. This work directly addresses the critical challenge of balancing oncologic control with renal function preservation. His most cited study (93 citations) prospectively evaluated how different resection techniques impact perioperative outcomes, acute kidney injury, and positive surgical margins after partial nephrectomy. Further research (36 citations) examined how surgical approach and technique influence "Trifecta" failure—the composite endpoint of cancer control, functional preservation, and complication avoidance—in highly complex renal masses. Karakoyunlu also led a major multicenter analysis identifying predictors of positive surgical margins after robot-assisted partial nephrectomy. His recent work extends to robotic radical prostatectomy, exploring how surgeon experience shapes outcomes. Through his leadership in the SIB International Consortium, Karakoyunlu has provided the urologic community with a reproducible, standardized language for reporting resection quality, directly improving surgical education and patient care.
