Laparoscopic uretero-ileal substitution preserving the natural anti-reflux mechanism: A case report.

Ureteral strictures constitute one of the most common sequelae of impacted ureteral stones. Uretero-ileal substitution is an established treatment for long benign ureteral strictures, measuring more than 2 cm, which are incurable by other less invasive treatment options. One of the common drawbacks of this procedure is its extensive nature and the urine reflux into the newly constructed ileal segment, resulting in urine stagnation and precipitation of urinary tract infections. We report a case of a minimally invasive laparoscopic uretero-ileal substitution for a long mid ureteral stricture, utilizing the natural anti-reflux mechanism.
