Bilateral robotic single-site partial nephrectomy.

We performed bilateral robotic single-site partial nephrectomy on a 51-year-old man with bilateral renal tumors. Left partial nephrectomy without renal arterial clamping and right partial nephrectomy with a warm ischemic time of 29 minutes were performed through a single umbilical port and one additional port. The total operative time was 350 minutes including 238 minutes of robotic console time. There were no operative complications and no open conversions. Follow-up exams over a 12-month period showed no tumor recurrence. Our report shows the technical feasibility of bilateral robotic single-site partial nephrectomy.
