Three cases of urinary-tract endometriosis with different clinical findings

Endometriosis is the presence of endometrium-like tissue outside the uterus. Ureteral involvement is rare and may result in a high rate of renal loss before it is recognized. Different treatment modalities are reported in the literature, including medical therapy and radical surgery. The authors report three cases of ureteral endometriosis with different clinical features. In one patient, bilateral distal ureterectomy and ureteroneocystostomy was performed, and the histopathologic diagnosis was consistent with intrinsic ureteral endometriosis. In the other two patients, surgical treatment consisted of endometrioma cyst excision, ureterectomy, and ureteroneocystostomy.
