title: Outcome of laparoscopic ureterolysis for ureteral endometriosis.
abstract: OBJECTIVE
  To evaluate the adequacy of laparoscopic ureterolysis as a primary treatment option for ureteral endometriosis.
  
  
  METHODS
  Prospective collaborative cohort study.
  
  
  METHODS
  Gynecologic departments of three university hospitals.
  
  
  METHODS
  Women with ureteral endometriosis exhibiting moderate-to-severe hydronephrosis on preoperative intravenous pyelography.
  
  
  METHODS
  Laparoscopic ureterolysis.
  
  
  METHODS
  Cure rate, disesase recurrence.
  
  
  RESULTS
  Thirty-three patients underwent laparoscopic ureterolysis during the study period. Bilateral involvement of ureters was found in 4 (12.1%) cases. In women with unilateral lesions the left ureter was more frequently affected (24/29 vs. 5/29). Ureteral involvement was associated with uterosacral ligaments endometriosis in 65.5% (22/34) of cases. No inadvertent ureteral injuries occurred during ureterolysis. A partial wall resection of the ureter was necessary in one case and a segmental ureteral resection with vescicopsoas hitch was required in a women with intrinsic ureteral endometriosis. The median (range) follow-up time was 16 months (range: 3-53 months). Thirty-two patients (96.7%) had a patent ureter on the 3-month postoperative intravenous pyelography. The recurrence rate of ureteral lesions was 12.1% (4/33).
  
  
  CONCLUSIONS
  Our findings suggest that a conservative laparoscopic approach is an effective treatment option in most patients with ureteral endometriosis exhibiting moderate-to-severe hydronephrosis.
