Abstract

PURPOSE:

The indications for laparoscopy in pediatric urology are expanding and yet the advantages over open surgery remain unclear. We compared the results of retroperitoneal laparoscopic vs open pyeloplasty for pyeloureteral junction obstruction in children.

MATERIALS AND METHODS:

A total of 22 children with a mean age of 88 months (range 25 to 192) underwent laparoscopic dismembered pyeloplasty via the retroperitoneal approach. An additional 17 children with a mean age of 103 months (range 37 to 206) underwent similar procedures via open surgery through a flank incision. We retrospectively analyzed and compared operative time, the use of analgesics (acetaminophen or morphine derivatives) and hospital stay.

RESULTS:

The 2 groups were similar in mean age and weight at surgery. Mean operative time was significantly shorter in the open surgery vs the laparoscopy group (96 minutes, range 50 to 150 vs 219, range 140 to 310, p <0.0001). Mean postoperative use of acetaminophen (1.9 vs 3.22 days, p = 0.03) and morphine derivatives (1.9 vs 3.06 days, p not significant) was less in the laparoscopy group. Mean hospital stay was shorter in the laparoscopy group than in the open surgery group (2.4 days, range 1 to 5 vs 5, range 3 to 7, p <0.0001). Mean followup was 21 (range 12 to 51) and 24 months (range 12 to 60) in the open and laparoscopy groups, respectively.

CONCLUSIONS:

The operative time of laparoscopic pyeloplasty remains significantly longer than that of the open procedure in children. The main advantage of the laparoscopic approach is that it significantly decreases hospital stay compared with that after an open procedure. Although in our study analgesic use was less after laparoscopy, our results should be confirmed by a prospective, randomized study.
