Holmium: YAG laser endoureterotomy in the treatment of ureteroenteric strictures following orthotopic urinary diversion.

The management of ureteroenteric strictures in patients who have undergone urinary diversion can be challenging. In those patients with an orthotopic neobladder, anastomotic ureteral strictures can be treated endoscopically using a retrograde or antegrade approach. The availability of small (7.5F) flexible ureteroscopes, as well as the use of the Holmium laser has facilitated the ability to precisely incise the stricture under direct endoscopic visualization (endoureterotomy). We describe our technique for laser endoureterotomy in patients with ureteroenteric strictures following orthotopic urinary diversion.
