Acquired rectovesical fistulas
Acquired rectovesical fistulas compose about 20% of all enterovesical fistulas. The most common causes include diverticulitis, Crohn's disease, trauma, and malignancy. Cancers of the cervix, prostate, bladder, colon, or rectum may cause fistulas between these two organs. Historically, however, infectious disease were more common causes. Such infections as typhoid, amebiasis, syphilis, and tuberculosis were likely etiologies previously.
Symptoms may include pneumaturia and fecaluria, as well as chronic urinary tract infections. Methods of diagnosis include CT imaging, cystography, barium enema, intravenous pyelography, and also cystoscopic or proctoscopic examination. Surgical correction of the fistula should be conducted to prevent cystitis and pyelonephritis.
