자궁경부암 환자에서 합병된 자궁내막증의 요관침범에 의한 경증의 수신증

The diagnosis of ureteral stricture caused by endometriosis can be difficult. Especially does in the case combined with other gynecological malignancies such as cervical cancer. We present a 50-year-old perimenopausal woman who had undergone radical hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy, and incidental appendectomy under the diagnosis of cervical cancer stage Ib1, who also had right ureteral endometriosis which was incidently found during operation and was treated with segmental resection and reanastomosis of the right ureter. Microscopic examination of the ureter and surrounding resected tissue confirmed the lesion to be typical endometriotic origin. Mild hydronephrosis on CT scan prior to operation made us to be confused with ureteral involvement by cervical cancer. However, when mild hydronephrosis or ureteral stricture exists in the case of an earlier stage of cervical cancer, physicians should consider a possibility of ureteral involvement rather by other causes like endometriosis than cancer invasion.
