Vesicointestinal fistula
Template:Short description Template:Infobox medical condition (new) A vesicointestinal fistula (or intestinovesical fistula) is a form of fistula between the bladder and the bowel.
Types
A fistula involving the bladder can have one of many specific names, describing the specific location of its outlet:
- Bladder and intestine: "vesicoenteric", "enterovesical", or "vesicointestinal"[1][2][3]
- Bladder and colon: "vesicocolic" or "colovesical"[4]
- Bladder and rectum: "vesicorectal" or "rectovesical"[5]
Symptoms and signs
If fecal matter passes through the fistula into the bladder, the existence of the fistula may be revealed by pneumaturia, fecaluria, or recurrent urinary tract infection. Migration of urine through the fistula into the bowel may cause rectal passage of urine.[6]

- diverticulitis : most common ~ 60%
- colorectal cancer (CRC) : ~ 20%
- Crohn's disease : ~ 10%
- radiotherapy
- appendicitis
- trauma
Diagnosis
Various modalities of diagnosis are available:[7]
- Cystoscopy
- Colonoscopy
- Poppy seed test[8]
- Transabdominal ultrasonography
- Abdominopelvic CT
- MRI
- Barium enema
- Bourne test[9]

A definite algorithm of tests is followed for making the diagnosis.
