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"
Bladder and colon: "vesicocolic" or "colovesical"
Bladder and rectum: "vesicorectal" or "rectovesical"
Symptoms and signs
If fecal matter passes through the fistula into the bladder, the existence of the fistula may be revealed by pneumaturia or fecaluria. [Source: Wikipedia
