Bladder, Vaginal and Rectal Fistulas
A fistula is an abnormal connection between two organs that are not usually connected. A fistula between the bladder and the vagina or the colon could cause your urine to smell bad. The fistula would allow bacteria into the bladder that is normally not present. This can make your urine smell bad.
What Causes a Bladder Fistula?
Bladder fistulas are usually caused by a previous surgery, Crohn’s Disease, diverticulitis, Inflammatory Bowel Disease, cancer or radiation therapy.
Treating fistulas involves removing them surgically.
