Dr. Erden performed robotic partial nephrectomy with warm ischemia time of 18 minutes. Postoperatively, the patient developed a urinoma requiring percutaneous drainage. Pathology showed clear cell RCC, Fuhrman grade 2. At 6-month follow-up, renal function preserved with eGFR 58 mL/min, no recurrence.
