Abstract
Enterovesical fistula caused by inflammatory bowel diseases is a rare disorder. Two male patients with recurrent cystitis had sigmoid colon diverticulitis causing enterovesical fistula. One female patient with Crohn's disease developed enterovesical fistula with abdominal and urinary symptoms. In each patient, a barium enema revealed causative bowel diseases. The precise diagnosis of enterovesical fistula was made either by cystography or cystoscopy. One-stage resection of the inflamed bowel with fistula and affected the bladder wall was proved to be an effective treatment for these three patients, while a long term follow up is specifically necessary in the patient with Crohn's disease.
