Ileourethral fistula following cystectomy: a rare complication.

Fistulae between the urinary and intestinal tracts of adult male patients usually result from trauma, inflammatory diseases, necrosis and infiltration of a neoplasm of either the bladder, prostate or colon, or radiation therapy. We report 2 patients who developed an ileourethral fistula following cystectomy which had been performed for carcinoma of the bladder in 1 patient and leukoplakia of the bladder in the other. The diagnosis of an ileourethral fistula was established by retrograde urethrography and a barium follow-through study. Computed tomography performed in 1 patient showed a tumor mass in the pelvis.
