Ten Cases of Colovesical Fistula due to Sigmoid Diverticulitis.

Colovesical fistula (CVF) resulting from colon diverticulosis is a comparatively rare disease, and neither the diagnosis nor treatment has been established. Our experience with CVF due to sigmoid diverticulitis over a 9-year period was reviewed to clarify the clinical presentation and diagnostic confirmation. Ten patients with CVF were identified in this period, and chief complaints, laboratory findings, presenting symptoms, diagnostic investigations, and subsequent treatments were reviewed.
