Introduction: Laparoscopic surgery has been increasingly used in urology in recent years. Laparoscopy has been performed at our center since 2001. Changes over time in the indication of open versus laparoscopic/robotic surgery, hospital stay, and learning curve are reviewed. Materials and methods: A retrospective review of our database from 1997 to the end of 2007. A total of 3622 procedures were performed during this time (endoscopic procedures were excluded): 67,75% open, 26,17% laparoscopic, 2,29% perineal, and 3,78% robotic surgeries. Of these, 83,79% were performed in males and 16,20% in females. Mean patient age was 58,8 years. Data from the study period, including mean hospital stay and changes over time in operating time as a function of the learning curve, were analyzed and compared to data for the last 12 months of the study period. Results: The percentages of all surgical procedures performed using a laparoscopic approach in the 1997-2006 versus the last 12 study months were as follows: nephrectomy, 31,8% versus 74,7%; living donor nephrectomy, 93% versus 100%; nephroureterectomy, 28,1% vs. 93,4%; partial nephrectomy, 31,3% vs 87%; and radical prostatectomy, 17,6% versus 73,5% including laparoscopic and robotic approaches. Shorter mean hospital stays and operating times were also seen. Conclusions: Use of the laparoscopic approach has greatly increased in the 10-year period studied. In renal surgery, few indications remain for open surgery. In prostate surgery, introduction of robotic surgery in 2005 and learning of laparoscopy by several of our urologists have dramatically changed the therapeutic approach. Gradual incorporation of laparoscopic surgery has led to a decreased hospital stay and to a shortening of the learning curve.
