Outcomes of Laparoscopic Partial Cystectomy of Bladder Endometriosis: A Report of 18 Thai Women

Aim: To determine the outcomes of laparoscopic partial cystectomy (LPC) for bladder endometriosis (BE). Methods: This was a retrospective study using medical records of women who underwent LPC for BE between January 2009 and December 2017. Demographic characteristics, surgical findings, including surgical site and size of the bladder lesion, endometriosis at other locations, and pre-A nd postoperative hormonal treatment data were collected. Results: We analyzed data of 18 women with full-thickness BE. The patients had a mean age of 34 (range, 26-45) years and body mass index of 21.6 (range, 16.1-25) kg/m2. All women had dysmenorrhea. Other symptoms noted include dysuria, gross hematuria, and infertility. BE with a mean diameter of 2.7 cm (range, 1-5) was most commonly found at the posterior wall of the bladder (94.4%). Peritoneal endometriosis (94.4%), endometrioma (33.3%), and deep endometriotic nodules (22.2%) in the posterior compartment were also found. No surgical complications were observed. Postoperative hormonal treatment was administered to 14 (77.8%) patients. All symptoms improved after the surgery. No recurrence was found after 30 (range, 12-74) months of follow-up. Conclusion: LPC is an effective treatment option for BE.
