Novel kidney segmentation system to describe tumour location for nephron-sparing surgery.

Purpose: To propose a novel system based on segmental renal anatomy for objectively reporting location of clinical T1 masses for nephron-sparing surgery.

Methods: The kidney was subdivided into 12 standard segments, based on the computed tomography images. In 103 patients (105 cT1 tumours), three blinded radiologists (A, B, and C) prospectively reported segmental tumour location, size, and tumour-feeding arteries.

Robotic intracorporeal urinary diversion: technical details to improve time efficiency.

Objectives: To present time-efficiency data during our initial experience with intracorporeal urinary diversion and technical tips that may shorten operative time early in the learning curve.

Patients And Methods: Data were analyzed in the initial 37 consecutive patients undergoing robotic radical cystectomy and intracorporeal urinary diversion in whom detailed stepwise operative time data were available. Median age was 65 years and median body mass index was 27.
