[Vesico-sigmoid fistula secondary to diverticulitis: a case report].

Vesico-sigmoid fistula is a rare complication of colic diverticular disease. It develops when the bladder sticks to an inflammatory colon making of a communication between the bladder and the digestive segment, usually the sigmoid. Liquid usually passes from the colon to the bladder because of the existing pressure gradient. Hence, urinary symptoms are the most frequent. Surgery is the treatment of choice. The present case is about a 72-year-old man who had a total hematuria for 3 months. The diagnosis of a vesico-sigmoid fistula secondary to colic diverticulitis was established by cystoscopy, colonoscopy and cystography. Surgery was underlaken and the postoperative outcome was excellent. Through this case the clinical features, special investigations and treatment of vesico-sigmoid fistula, are reported.
