title: [A case of ileal conduit stenosis 13 years after construction].
abstract: A 63-year-old male was admitted to our hospital with the complaint of bilateral hydronephroses. Total cystectomy and ileal conduit construction were performed because of bladder tumor (TCC, G2, pT2N0M0) in 1985. The patient remained asymptomatic, but bilateral hydronephroses was observed by ultrasonography in 1997. DTPA renogram showed the delayed excretion. Conduitgraphy and antegrade pyelography revealed that the conduit was narrow like a pinhole at 2 cm distal region from the anastomotic site of the urinary duct. The stenotic region was inflated by a 24 Fr inflation-balloon-catheter. Chronic inflammation, which was thought to be caused by infection, was detected at the stenotic conduit by biopsy. Hydronephroses disappeared after the operation and the postoperative course was uneventful.
