Endometriosisによる尿管通過障害の1例

URETERAL OBSTRUCTION FROM ENDOMETRIOSIS

緒言

　endometriosisとは子宮内膜組織あるいは子宮内膜由来の組織が異所性に発育し，月経周期に一致して子宮内膜と同様の変化を示し，その結果，種々の症状を呈するものをいう。

　endometriosisはごく普通にみられる疾患で，初経から閉経までの婦人の8〜15％にも及ぶという（Hawthorone,1951）。しかし，その発生部位は女性性器あるいは骨盤内腹膜に多く，尿路に発生することは比較的まれのようである（第1表）。また，尿路のendometriosisとしては，圧倒的に膀胱に発生した例の報告が多く，その他の尿路に発生した例の報告は極めて少ない（第2表）。

A case of endometriosis complicated with ureteral obstruction, in a 45 year old house wife, who had been compiaining dull lower abdominal pain few days before menstruation for more than 10 years but was not treated since it was considered as period pain, was reported. Patient visited a local docter, 6 weeks before her first visit to our clinic, for right flank pain and fever, and was diagnosed as urinary infection. Symptoms were relieved by treatment but right renal abnormality was pointed out by I.V.P. and was referred to our clinic for further evaluation.
