Background and Objectives: To compare postoperative complications in patients undergoing laparoscopic and open partial nephrectomy using a standardized complication- reporting system and a standardized tumor-scoring system. Methods: We conducted a retrospective analysis of 189 consecutive patients with nephrometry scores available who underwent elective partial nephrectomy for renal masses. Demographic, perioperative, and complication data were recorded. By using the modified Clavien scale, we graded 30- and 90-day complication rates. Results: 107 patients underwent laparoscopic partial nephrectomy and 82 underwent open partial nephrectomy (N=189). Open partial nephrectomy patients had higher nephrometry scores than laparoscopic patients had (7.1±2.4 vs. 5.6±1.8, P<.001). Surgical and hospitalization times were shorter, and estimated blood loss was lower in the laparoscopic group (P<.001). At 30 days, there were more overall complications in the open group, but more major complications in the laparoscopic group (P>.05). After multivariable logistic regression analysis, only higher body mass index and higher estimated blood loss were predictors of more overall complications. Conclusions: Laparoscopic partial nephrectomy has the advantages of decreased operative time, lower blood loss, and shorter hospital stay. The complication rate in the laparoscopic group is similar to that in the open group, despite favorable tumor characteristics in the laparoscopic group.
