Objective:
To evaluate prospectively the efficacy of laparoscopic ureterolysis versus ureteroureterostomy in women with ureteral endometriosis.
Design:
Prospective study.
Setting:
Department of Obstetrics and Gynecology, Ospedale Sacro Cuore of Negrar, Verona, Italy, a tertiary care endometriosis referral center.
Patient(S):
Endometriotic patients with moderate-severe ureter dilatation.
Intervention(S):
All women underwent laparoscopic endometriosis excision and concomitant laparoscopic ureterolysis, ureteroureterostomy, nephrectomy, or laparotomic ureterocystoneostomy.
Main Outcome Measure(S):
Clinical outcomes were evaluated.
Result(S):
Fifty-six patients with preoperative or intraoperative evidence of moderate-severe ureter dilatation were enrolled. Dysmenorrhea (91%) and dyspareunia (68%) were the symptoms more frequently reported; only two patients had typical obstructive uropathy pain. In 35 cases, laparoscopic ureterolysis, in 17 laparoscopic ureteroureterostomy, in 2 laparotomic ureterocystoneostomy, and in 2 laparoscopic nephrectomy was performed. 11 out of 35 (31.4%) major complications occurred in the ureterolysis group, and 2 out of 17 (11.7%) in the ureteroureterostomy group. Median follow-up time was 21 months. Ureteral endometriosis recurrence was surgically detected in three patients who underwent conservative ureteral surgery.
Conclusion(S):
Preoperative planning should be rigorous, and complete surgical excision of ureteral endometriosis should be ensured by a team of experts familiar with endometriosis, its multiple manifestations, and its management.
