Objectives:
To report our experience with laparoscopic pyeloplasty in the treatment of pyeloureteral junction obstruction.
Methods:
Between August 2001 and August 2004 14 patients with the diagnosis of pyeloureteral junction obstruction underwent laparoscopic repair. Seven cases had the obstruction on the left side and the other seven on the right side. We describe the technique of laparoscopic dismembered Anderson-Hynes type pyeloplasty, performed to 12 patients in our series. The remainder 2 patients underwent Foley's Y-V plasty and the Fenger's technique.
Results:
Mean operative time was 199.7 minutes (r: 126-290). There were not intraoperative complications. Mean hospital stay was 4.63 days (r: 3-9). One case of double J catheter obstruction can be cited as late postoperative complication. Only one of the 14 cases suffered a recurrence of the stenosis after double J catheter retrieval.
Conclusions:
Laparoscopic pyeloplasty has become the operation of choice in cases of hydronephrosis secondary to crossing vessel, when there is great pyelic dilation, and for the treatment of failures of previous endopyelotomy.
