title: Urinary bladder endometriosis: a report of two cases.
abstract: Endometriosis of the urinary tract is uncommon, and the most common site of involvement is urinary bladder. Two cases of endometriosis of urinary bladder are presented. The first patient, a 39-year-old woman, complained of dysuria during menstruation and the other 37-year-old woman suffered from intermittent gross hematuria. Pre-operative examinations included ultrasonography, computed tomography and cystoscopic biopsy. Case 1 was in premenopausal status, but the serum estrogen level of case 2 was in postmenopausal status because she was given no exogenous estrogen after previous bilateral salpingo-oophorectomy. Endometriosis of urinary bladder rarely occurs in postmenopausal woman without exogenous estrogen replacement. Case 1 received danazole treatment after transurethral resection of bladder tumor and case 2 received partial cystectomy after transurethral resection of bladder tumor. The patients were followed 36 and 4 months, respectively, and the symptoms kept improving during this period.
