title: Laparoscopic pyeloplasty: evolution of a new gold standard.
abstract: OBJECTIVE
  To report our series of laparoscopic dismembered pyeloplasty for the treatment of primary and secondary ureteropelvic junction obstruction and to review the current status of this procedure.
  
  
  METHODS
  A total of 170 consecutive cases of laparoscopic pyeloplasty (156 for primary and 14 for secondary ureteropelvic junction obstruction) were performed or supervised by a single surgeon (C.G.E). A four-port extraperitoneal approach was used in all but 3 cases, which were performed transperitoneally.
  
  
  RESULTS
  The median operative time was 140 minutes. The complication rate was 7.1%, and the conversion rate was 0.6%, with no conversion in the last 161 cases. The median postoperative hospital stay was 3 nights. Crossing vessels were encountered in 42% of cases, and in 11 patients, coexisting renal calculi were successfully removed. At a median follow-up of 12 months, the success rate was 96.2%.
  
  
  CONCLUSIONS
  Laparoscopic dismembered pyeloplasty produces functional results comparable to that of open surgery with the advantages of a minimally invasive procedure. Our results are consistent with previous series and support the view that laparoscopic pyeloplasty is moving rapidly toward replacing open surgery as the gold standard in the treatment of ureteropelvic junction obstruction.
