6 The most common symptoms are urinary abnormalities,
which involve dysuria, recurrent urinary tract
infection, pneumaturia, and fecaluria.6–8 Enterovesical
fistula is diagnosed by cystoscopic examination, voiding cystourethrogram,
barium enema, and abdominal and pelvic
portion computed tomography (CT) scan. Cystoscopic
examination shows changes suggestive of fistula in 79% of
cases.8 Abdominal and pelvic portion CT scan gives the
most accurate diagnosis of this disease by revealing air in
the bladder and localized hypertrophy or adhesion of the
bladder wall and the intestinal tract wall.2,7 The diagnostic
rate is improved by performing these tests in combination.6
In the present patient, the abdominal and pelvic portion CT
scan did not reveal the presence of the enterovesical fistula,
and the diagnosis and the fistula site were determined by
voiding cystourethrogram and cystoscopic examination.
