Partial Nephrectomy in Clinical T1b Renal Tumors: Multicenter Comparative Study of Open, Laparoscopic and Robot-assisted Approach (the RECORd Project)

Objective To evaluate perioperative results of open (OPN), laparoscopic (LPN), and robot-assisted partial nephrectomies (RAPN) and to identify predictive factors of Trifecta achievement for clinical T1b renal tumors in a multicenter prospective dataset. Methods Data of 285 patients who had OPN (133), LPN (57), or RAPN (95) for cT1b renal tumors were extracted from the RECORd Project. High-volume centers were defined as 6550 overall cases of partial nephrectomy per year. Trifecta was defined as simultaneous absence of perioperative complications, negative surgical margins, and ischemia time
