TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: To analyze the complications according to the Clavien classification after laparoscopic partial nephrectomy (LPN) and Robotic-assisted partial nephrectomy (RPN).

wceMethods: We analyzed consecutive LPN (n = 85) and RPN (n = 93) cases at our institution between April 1994 and December 2012. The data were retrospectively reviewed froma prospectively collected database. All complications that occurred within 3 months postoperatively were recorded and classified according to the modified Clavien classification system.

Results: The mean tumor size was 3.90 +/- 1.77 cm. The mean operative time was 255.0 +/- 83.5min, and the mean warm ischemia time was 31.6 +/- 22.0min. The overall complication rate was 18.5%. Clavien grades 1, 2, 3a, and 3b complications accounted for 3.93%, 11.2%, 2.81%, and 1.69% patients, respectively. The most common complication was perioperative hemorrhage, which required blood transfusion. Delayed bleeding occurred in 7 patients and 4 patients underwent angiographic embolization. The proportions of intermediate and high PADUA score (≥ 8) and RENAL score (≥ 7) are 70.8% and 74.2% respectively. A higher PADUA or RENAL score was associated with a significantly greater complication rate (p = 0.024 and 0.02 respectively).

Conclusions: The overall complication rate in the present study was comparable to that reported in previous studies, although our patients had a larger mean tumor size and higher complexity procedures.
