Step-by-step explanation:
The abnormal opening between the bladder and vagina is called a vesicovaginal fistula. The maintenance of this fistula is not a normal function of the body, but rather a complication that can occur due to injury, infection, or other medical conditions.
In some cases, surgical intervention may be necessary to repair the fistula and restore normal function to the bladder and vagina. Treatment options may include reconstructive surgery or other medical procedures, depending on the underlying cause of the fistula.
