Abstract:
PURPOSE: To describe our initial experience of laparoscopic pyeloplasty, with retrograde stenting, using flexible cystoscopes, in 9 cases of ureteropelvic junction obstruction (UPJO). MATERIALS AND METHODS: Between September, 2004 and January, 2006, 9 cases of UPJO were treated by laparoscopic pyeloplasty. All of the medical records were reviewed retrospectively. The cases comprised of 5 males and 4 females, with a mean age of 37 years (13-58). All patients showed a preoperative grade 4 hydronephrosis. RESULTS: Two laparoscopic pyeloplasty approaches were performed; a transperitoneal approach in 5 cases and a retroperitoneal approach in the other 4. All cases were treated with dismembered Anderson-Hynes pyeloplasty. The mean operating time was 249 minutes (170-324), including a mean of 7.1 minutes (6.5-8) for ureteral stenting. The patients were found to have aberrant vessels and renal stones in 1 and 3 cases, respectively. There were no intra-operative complications or open conversion. Of the 9 cases, 8 (89%) showed a decrease in their hydronephrosis grade on the excretory urographs taken 12 weeks postoperatively. The remaining case showed a marked improvement in the hydronephrosis, despite having no change in the hydronephrosis grade. No case experienced postoperative flank pain or recurrence of acute pyelonephritis. Therefore, symptomatic improvements were observed in all our cases (100%). CONCLUSIONS: Laparoscopic pyeloplasty, with retrograde stenting, using flexible cystoscopes, can be considered an effective and convenient method for the treatment of UPJO.
