Cho, Lee, Kim, Kim, and Kim: Ureteral Endometriosis

Abstract

Endometriosis is defined as the presence of functional endometrial tissue in an ectopic site. The incidence of endometriosis is from 10% to 20% for women of reproductive age. From 1% to 2% of woman with endometriosis have urinary tract lesions, of which from 70% to 80% involve the bladder. Yet ureteral endometriosis is very uncommon, and it is noted in only 0.1% to 0.4% of these cases. We report here on one case of ureteral endometriosis.
