To determine whether the approach for partial nephrectomy is influenced by tumor complexity and if the introduction of robotic techniques has allowed us to treat more complex tumors minimally invasively. Data from 292 patients who underwent partial nephrectomy for renal masses from November 1999 to July 2013 at a tertiary referral center were retrospectively reviewed. Nephrometry scores and perioperative outcomes were stratified based on when robotic techniques were introduced. Mean follow-up time was 2.6 years. Preoperative RENAL nephrometry scores and perioperative outcomes were analyzed. Of the 292 patients, 31.5 % underwent robot-assisted partial nephrectomy, 46.2 % laparoscopic partial nephrectomy and 22.9 % open partial nephrectomy. Robot-assisted partial nephrectomy mean nephrometry score was significantly higher than laparoscopic and equivalent to open. Significant perioperative differences were estimated blood loss (p = 0.0001), length of stay (p = 0.0001) and Clavien score (p = 0.0069), all favoring robot-assisted partial nephrectomy. Limitations include retrospective design and single center data. Robot-assisted partial nephrectomy is a safe and effective surgical modality that allows for complex renal tumors that were previously reserved for open partial nephrectomy in the pure laparoscopic era to be managed with a minimally invasive approach.
