Abstract
Laparoscopic pyeloplasty represents one of the more advanced reconstructive procedures for the urologist. While early reports were replete with long operative times, there have been several changes that have added to the efficiency of the procedure. In our practice, we have found three changes to be of greatest value: (1) an upper-midline port placement; (2) use of a continuous suture for the anastomosis with a double-armed, knotted suture; and (3) antegrade stent placement.
