子宮內膜異位症侵犯到泌連系統的機率非常小，但一旦被侵犯就常造成很嚴重的泌尿系統的傷害，甚至產生同側腎臟功能完全喪失，尤其輸尿管子宮內膜異位症最常造成腎臟傷害。由於泌尿系統子宮內膜異位症的臨床表現無特異性，要早期診斷及正確的治療實所不易，唯有臨床醫師要有高度的警覺及詳細正確的骨盆腔物理檢查。對於子宮內膜異位的病人應做靜脈腎盂攝影檢查，是否尿路系統已被侵犯，對於生產年齡的婦女如有遠側輸尿管非結石性的狹窄阻塞，輸尿管子宮內膜異位症應列入考慮疾病之一。本院從1981至1990年，共有兩例輸尿管子宮內膜異位症，壹例膀胱子宮內膜異位症。在此描述這些病人臨床症狀，診斷及治療經過，並回顧文獻報告。

Although endometriosis involiving the urinary tract is rare, it is responsible for considerable morbidity. We report 3 successfully treated cases of endometriosis involiving urinary tract. In two patients uretera obstruction secondary to endomteriosis were noted; in the third patient vesical endometriosis wad defined. Because of these nonspecific clinical presentations and possible irreversible renal damage, a high index of suspicion of the deisease and careful physical and pelvic examination are necessary to early diagnosis and treatment. The liberal use of intravenous urography even in cases of minimal endometriosis is urged. The clinical features, diagnosis, and mangement of endometriosis involving urinary tract are discussed, based on our experience and review of the literatures.
