Videoendoscopic surgery by extraperitoneal access: technical aspects and indication.

Laparoscopic surgery in urology is definitely incorporated to the techniques of minimally invasive treatment for urogenital diseases. Though the classic access to organs in the urinary tract is extraperitoneal, this access has not been prioritized when the videoendoscopic technique is used. In Brazil, few groups use this approach and little has been discussed about its true practical applicability. The authors intended to discuss the main technical aspects and criteria for indication, reported though the improvement achieved in a 5-year period with 150 operated cases. A review of the literature shows that the worldly acceptance of the extraperitoneal endoscopic approach is increasing. Nevertheless, there are no evidences that the extraperitoneal access is superior to the transperitoneal route. Thus, the choice depends basically on the surgeon's preference. Major advantages are the immediate access to the renal hilum and isolation of peritoneal structures. Employing this access is useful when one suspects that significant peritoneal adherences could prevent the surgical act or when one wishes to preserve the integrity of the peritoneal cavity.
