Vesicorectal Fistula, Case Report and Review of Literature

Approximately 20% of all enterovesical fistulas are rectovesical. The common causes of acquired vesicoenteric fistula have shifted from diseases of the past (e.g. typhoid, amoebiasis, syphilis, tuberculosis) to diverticulitis, malignancy, Crohn’s disease and iatrogenic causes. Rectovesical fistulas are frequently associated with malignancy. Interestingly, bladder carcinoma rarely, if ever, is associated with fistula formation. Rarely, the bladder can be the origin of the inflammatory process. It is extremely rare that the urinary bladder stones can fistula into the rectum and cause vesicorectal fistula.
