Clinical evaluation of ureteral endometriosis: report of 8 cases

We report 8 cases of ureteral endometriosis. The mean age of the 8 patients was 42 years (range 29 to 60). In all patients, endometrial lesions were located in the lower third of the ureter and were unilateral. Six patients presented with flank pain and in one of the 6 cases the pain was associated with menses. One presented with gross hematuria. One had no symptoms. Seven out of 8 cases had gynecological diseases and 4 had had surgical treatment for the gynecological diseases. Four patients were treated with gonadotropin-releasing hormone (Gn-RH) analogue for hydronephrosis of endometriosis. In 2 patients, the therapy was effective, but hydronephrosis recurred. Surgical therapy was done on all patients. We recommend surgical therapy for hydronephrosis with ureteral endometriosis.
