Endoscopic Management of A Ureteral Obstruction Caused by Endometriosis: A Case Report

Abstract

Ureteral obstruction secondary to endometriosis is relatively uncommon. We present a 49-year-old female (gravida 3, para 2, abortion 1), who was identified as suffering from right hydronephrosis while undergoing her regular health examination. Retrograde pyelography demonstrated a partial obstruction of the right ureter in the distal third. She underwent ureteroscopy and biopsy to remove a right ureteral tumor. Histological examination confirmed ureteral endometriosis. During follow-up at the obstetrics and gynecology outpatient department, an abdominal echo was detected that revealed a right endometrioma (size, 7.5 × 4.8 × 5.5 cm) on the ovary. As a result, a total hysterectomy and bilateral salpingo-oophorectomy was performed. Although the patient had right residual hydronephrosis, the creatinine level improved to 1.2 mg/dL during follow-up.
