[Eight cases of pyelo-ureteral junction syndrome treated by laparoscopic surgery]

From may 1994 to may 1995, eight consecutive patients with symptomatic congenital ureteropelvic junction syndrome (UPJS) were treated by pyeloplasty as described by Anderson, Hynes and Küss by laparoscopic surgery. Three patients had a lower pole artery crossing the anterior surface of the junction and two had a giant renal pelvis. The mean operating time was 120 minutes (min: 90 min; max: 147 min) and the mean hospital stay in the absence of complications (one case) was 3.5 days (min: 1.5 day; max: 8 days). This one complication was due to a postoperative fistula resulting from a technical error requiring an additional fortnight in hospital. All the patients are evaluable at three months. All are asymptomatic and the radiological results showed frank improvement in seven out of eight cases, while the dynamic appearance was improved in the other case. UPJS can be treated by laparoscopic surgery according to proven surgical principles, provided it is performed in a perfectly equipped operating room, by a surgeon and operating team experienced in this type of surgery.
