Comparison of retroperitoneal and transperitoneal robotic partial nephrectomy for Pentafecta perioperative and renal functional outcomes

We compared quality outcomes between transperitoneal (TRPN) and retroperitoneal robotic partial nephrectomy (RRPN). Two-center retrospective analysis of TRPN and RRPN from 10/2009 to 10/2015. Perioperative/renal function outcomes were analyzed. Primary endpoint was Pentafecta, a composite measure of quality [negative margin, no 30-day complication, ischemia time ≤25 min, return of glomerular filtration rate (eGFR) to >90% from baseline at last...
