PURPOSE: We report our experience with the extraperitoneal approach to laparoscopic radical prostatectomy. We describe the technique, clinical and oncological results, and functional outcome. MATERIALS AND METHODS: From February 2002, to March 2004, 600 laparoscopic radical prostatectomies were performed by an extraperitoneal approach and evaluated prospectively. RESULTS: A total of 599 extraperitoneal procedures were performed successfully. Mean operative time was 173 minutes. Mean operative blood loss was 380 cc. The transfusion rate was 1.2%. The major and minor complications rate was 2.3% and 9.2%, respectively. The reoperation rate was 1.7%. Mean hospital stay was 6.3 days. Pathological stage was pT2 and pT3 in 72% and 28% of cases, respectively. Mean Gleason score was 7. The overall positive margin rate was 17.7% (14.6% and 25.6% of pT2 and pT3 tumors, respectively). Median followup was 12 months. Of the patients 95% had prostate specific antigen less than 0.2 ng/ml. Patients were evaluated by a self-questionnaire sent by mail before and after surgery (International Continence Society and International Index of Erectile Function-5). At a median followup of 12 months 84% of the patients were continent (no pad), 7% used 1 precautionary pad and 7% needed 1 pad routinely. At a median followup of 6 months in preoperatively potent patients (International Index of Erectile Function-5 greater than 20) the postoperative erection and intercourse rate was 64% and 43%, respectively, in those with bilateral nerve bundle preservation. CONCLUSIONS: The extraperitoneal technique is a reliable approach to laparoscopic radical prostatectomy.
