A case of balloon dilatation of ileal conduit stenosis

　71歳，女性。子宮頸癌に対し1982年広汎子宮全摘出術および放射線療法を受けた後，萎縮膀胱をきたし1989年に回腸導管造設術を受けた。徐々に水腎症の悪化，導管の狭窄を認めたため狭窄部のバルーン拡張術を行い，改善を得た。

　A 71-year-old female underwent ileal conduit construction in 1989 because of contacted bladder after radical hysterectomy and radiation therapy.The patient had recurrent pyelonephritis,and bilateral severe hydronephrosis was observed by intravenous pyelography（IVP）in 2001.Conduitography revealed that ileal conduit was stenotic.15mm-diameter balloon was placed at stenotic region and was inflated for about 2minutes.IVP at 2months after balloon dilatation showed that bilateral hydronephrosis was improved.
