Considering this, what is a Colovesical fistula?
A colovesical fistula (CVF) is an abnormal connection between the colon and urinary bladder. Although they are uncommon, CVFs can cause significant morbidity, affect quality of life, and may lead to death, usually secondary to urosepsis [1,2].
In this way, what is the most common cause of Colovesical fistula?
The most common cause of colovesical fistula is diverticulosis; however, it may be caused by malignant diseases, Crohn's disease, radiation, etc. The underlying mechanism is the direct extension of a ruptured diverticulum or secondary erosion of a diverticular abscess into the bladder [9, 10].
A fistula is a tract or opening that forms under the skin from the anus to outside of the body. A fistula will not heal without treatment, which involves removing the pocket where the infection started.
