Ureteral plication. A new concept in ureteral tailoring for megaureter.

Currently, the most favored surgical procedure used to restore normal peristalsis to massively dilated adynamic ureters is ureteral tailoring. This procedure, however, seriously jeopardizes the ureter's blood supply and frequently results in ischemia with ureteral stenosis and further renal deterioration. To preserve the distal ureter's vasculature a new technique of reducing ureteral caliber and restoring normal peristalsis with minimal disruption of the blood supply was developed and performed in 14 dogs with excellent results.
