A three-trocar technique for limited laparoscopic renal surgery

Laparoscopic renal surgery usually involves the use of five or six trocars. This report concerns the authors' technique for performing such surgery through only three trocars. Semilateral patient positioning, along with additional table rotation, is utilized to facilitate visceral rotation and optimize exposure of the kidney. Four laparoscopic renal procedures were performed: one renal cyst decortication and three upper pole partial nephrectomies with ureterectomies for duplications of the collecting system. Mean operative time was 148 min with no conversions; there were no intra- or postoperative complications. All patients tolerated a liquid diet on postoperative day 1, and the median hospital stay was 2 days. In selected cases laparoscopic renal surgery may be approached safety through three trocars.
