Laparoscopic resection and ureteroureterostomy for congenital midureteral stricture.

A 16-year-old boy presented with flank pain and was found to have right-sided hydronephrosis and hydroureter on ultrasonography and an intravenous urogram. A retrograde pyelogram revealed a tight, short-segment, non-negotiable stricture in the midureter. A CT scan excluded extrinsic compression. In the absence of any other pathology, the stricture was considered to be congenital. The diseased segment of the ureter was resected laparoscopically, and an intracorporeally sutured ureteroureterostomy was fashioned over a double- J stent. The patient made an uneventful recovery and was well at follow-up 18 months later. To the best of our knowledge, this is the first reported case of laparoscopic resection of a congenital midureteral stricture.
