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.
