Outcomes of surgical management of deep infiltrating endometriosis of the ureter and urinary bladder.

OBJECTIVES

To report the outcomes of surgical management of urinary tract endometriosis and discuss the choice between conservative and radical surgery.

MATERIALS AND METHODS

We reviewed data concerning women managed for ureteral or bladder deep infiltrating endometriosis in 5 surgical departments participating in the CIRENDO prospective database. Preoperative data, surgical procedure data, and postoperative outcomes were analyzed.

RESULTS

Data from 30 women pooled in the database showed 15 women presenting with ureteral endometriosis, 14 women with bladder nodules, and 1 with both types of lesions. Ureterolysis was performed in 14 cases; the ureter was satisfactorily freed in 10 of these. In 4 women over 40 years old, who were undergoing definitive amenorrhea, moderate postoperative ureteral stenosis was tolerated and later improved in 3 cases, while the fourth underwent secondary ureteral resection and ureterocystoneostomy. Primary ureterectomy was carried out in 4 women. Two cases of intrinsic ureteral endometriosis were found in 5 ureter specimens. Four complications were related to surgical procedures on ureteral nodules, and 2 complications followed the removal of bladder endometriosis. Delayed postoperative outcomes were favorable with a significant improvement in painful symptoms and an absence of unpleasant urinary complaints, except for one patient with prolonged bladder denervation.

CONCLUSION

Conservative surgery, in association with postoperative amenorrhea, can be proposed in a majority of cases of urinary tract endometriosis. Although the outcomes are generally favorable, the risk of postoperative complications should not be overlooked, as surgery tends to be performed in conjunction with other complex procedures such as colorectal surgery.
