Transperitoneal vs. retroperitoneal robotic partial nephrectomy: a matched-paired analysis

Purpose When performing robotic nephron-sparing surgery (NSS) for renal tumors, either a transperitoneal approach or retroperitoneal approach can be utilized. The operative technique for robotic retroperitoneal partial nephrectomy (RPPN) is discussed and a matched-paired analysis comparing both RPPN and transperitoneal partial nephrectomy (TPPN) at a single institution is discussed. Materials and methods A retrospective review over a 10-year period (2006–2016) was performed for all patients who underwent robotic partial nephrectomy. A total of 281 patients underwent RPPN and 263 patients underwent TPPN. A matched-paired analysis was performed on 166 pairs of patients and the outcomes reviewed. Results Operative time ( p
