Recto-vesical fistula is an anomalous communication (fistulous tract) between the bladder and the rectum. The common etiologies are diverticulitis, Crohn’s disease, irradiation, traumatic, bladder or colo-rectal cancer and tuberculosis.
Common symptoms of presentation are fecaluria (presence of feces in the urine), pneumaturia (passage of gas in the urine), hematuria (presence of blood or clots in the urine), intestinal symptoms, abdominal pain, and fever/chills.
Evaluation: urine test (urinalysis) shows food fibers, fecal particles, bacteria, white blood cells and red blood cells.
Cystography shows fistulous tract and bladder inflammation, as seen in this picture, which is a diagnostic/evaluation method barely used because of availability of CT scans.
Later I will give you the fast facts about treatment of this condition.
