Current and future roles of laparoscopic surgery in urology.

There is little doubt that laparoscopy will gain an increasing role in urologic surgery. Pelvic node dissection, varicocelectomy, and evaluation of nonpalpable undescended testes are already widely performed. As improved instrumentation is developed expressly designed for urologic applications, there will be even greater interest and wider applicability of laparoscopic techniques. However, as this occurs, it is essential that each new procedure be critically evaluated to be certain that it offers significant benefit without added morbidity as compared with standard techniques.
