Endopyelotomy in the age of laparoscopic and robotic-assisted pyeloplasty

Abstract

Ureteropelvic junction obstructixon (UPJO) management has undergone significant changes in the past few years. The aim of this review is to establish the role of endopyelotomy in the age of laparoscopic and robot-assisted laparoscopic pyeloplasty (RALP). Open pyeloplasty (OP) has been the gold standard of care for UPJO for the past six decades. Due to lower long-term efficacy, endopyelotomy has failed to replace OP. However, laparoscopic pyeloplasty (LP) has been able to reproduce the high success rates of OP, while also achieving minimal morbidity. Unfortunately, the steep learning curve and technical difficulties have hindered its use. Recently, robot-assisted systems have enabled LP to overcome its disadvantages, and this may render endopyelotomy obsolete. Although LP and RALP are emerging as the gold standard of treatment for UPJO, endopyelotomy could carve out a niche area as a salvage procedure. Endopyelotomy will continue to have a role in the management of UPJO, albeit a smaller one.
