Thirty-four patients with colovesical fistulas seen over a recent 10 year period were reviewed. Diverticulitis was the most common cause of colovesical fistula, accounting for 71 percent of patients in our series. The majority of patients present electively, and most have urinary tract complaints. ⋯ Operations in three stages for colovesical fistula are not indicated. The primary objectives in the management of colovesical fistulas due to unresectable malignancy are relief of intestinal and urinary obstruction and fecal diversion. Resection of the malignancy should be performed whenever possible.
