Endoscopic management of the obliterated ureteroileal anastomosis.

Endoscopic restoration of a totally obstructed ureteroileal anastomosis was accomplished in 3 patients. The combined use of rigid endoscopy of the ileal conduit and flexible nephroureteroscopy provided full visualization of the blind-ending segments and allowed location of the shortest segment between the lumina. A guide wire was passed through intervening tissue with fluoroscopic monitoring to re-establish internal drainage. This technique offers an alternative to laparotomy and reimplantation in selected cases of ureteroileal stricture.
