to report a single expert robotic surgeon step-by-step surgical technique for achieving local cancer control during robotic PN (RPN) for T3 tumors.
Since January 2010 to December 2016, the institutional RPN database was queried for patients who underwent transperitoneal RPN performed by a single-surgeon for tumors ≤ 4 mm from the collecting system at preoperative computed tomography (3 points on the "N (Nearness)" RENAL-score item) that were pT3a involving sinus fat at final pathology.
