Urinary tract fistulas can form between any part of the urinary tract and structures in the thoracic cavity, the abdominal cavity, the pelvis, and the skin.
- Colovesical fistula:
- Usually complication of primary GI disease such as diverticular disease (most common), Crohn's disease, or colon carcinoma
- Iatrogenic (postsurgical or radiation treatment most common)
- Urethral disruption from trauma
- More common in males
- Vesicovaginal, urethrovaginal, and ureterovaginal fistulas:
- Vesicovaginal fistula is the most common acquired fistula of the urinary tract
- Etiology varies with geography (developed vs. developing countries):
- In developed countries it is usually due to injury to the structures during surgery, pelvic pathology, radiation therapy, or injuries incurred in the healing process. Radiation-induced fistulas may not present for months to years after exposure.
- In developing countries it is usually due to obstructed labor and obstetric trauma.
