title: Percutaneous endopyelotomy.
abstract: Percutaneous endopyelotomy, introduced over 15 years ago, is a well-established alternative to open operative pyeloplasty for management of ureteropelvic junction (UPJ) obstruction. Although several variations of the technique have been described, the goal in all cases is to develop a full thickness incision though the obstructing proximal uretra that extends out to the peripyeloureteral fat and heals over an internal stent. Though a percutaneous endopyelotomy can be considered for almost any patient with primary or secondary UPJ obstruction, it is particularly valuable in the setting of upper tract stones that can then be managed simultaneously. This article reviews the indications, techniques, and outcomes of percutaneous endopyelotomy.
