Laser endoureterotomy with hormonal therapy failed to adequately treat intrinsic ureteral endometriosis, with most patients experiencing recurrence and altered receptor expression.

The paper retrospectively evaluated six patients with intrinsic ureteral endometriosis treated with laser endoureterotomy, analyzing postoperative clinical outcomes and hormonal therapy effects, and performing immunohistochemistry for estrogen (ER) and progesterone (PR) receptor expression on pathological sections compared with normal endometrium controls. Recurrence of ureteral stricture occurred in five patients within 6 months despite 3 to 6 months of hormonal therapy, and one additional patient had recurrence 8 months after surgery. Two patients required secondary surgery (ureteroureterostomy), with pathology confirming recurrent endometriosis, and immunohistochemistry showed decreased ER and PR expression compared to controls. This paper is centrally about endometriosis — it specifically tests and finds laser endoureterotomy is not sufficient for managing intrinsic ureteral endometriosis.

Abstract

AIM: To investigate whether intrinsic ureteral endometriosis could be managed by laser endoureterotomy. MATERIAL AND METHODS: We studied retrospectively 6 patients with intrinsic ureteral endometriosis who underwent laser endoureterotomy and reviewed their clinical data. Pathological sections of them have also been studied by immunohistochemistry for expressional levels of oestrogen (ER) and progesterone (PR) receptors. Ten sections of normal endometrium were included as a control. RESULTS: Five patients had recurrence of ureteral stricture within 6 months postoperatively despite hormonal therapy for 3 to 6 months. One patient had recurrence 8 months after endoureterotomy. Two patients had secondary surgery for ureteroureterostomy and pathology confirmed recurrence of endometriosis. Immunohistochemistry revealed decreased ER and PR expression compared to the control. CONCLUSIONS: Endoureterotomy with hormonal therapy may not be suitable for ureteral endometriosis due to inadequate cutting and expressional change of ER and PR.
