Laparoscopic Boari flap for treatment of benign midureter stricture.

Introduction:: Laparoscopic ureteral reconstructive surgery represents a real challenge for most of the urologists as it requires advanced skills. Impacted stones (>2 months) and endoscopic procedures are known major risk factors for ureteral strictures. Boari flap is a good alternative, due to the high recurrence of kidney stone disease, as it preserves the feasibility of ureteroscopy.
