According to the World Health Organization (WHO), an estimated 50,000 to 100,000 women develop obstetric fistulae each year and over two million women currently live with an obstetric fistula. [61] In particular, most of the two million-plus women in developing nations who develop obstetric fistulae are under the age of 30. [ 46 ]
A ureterovaginal fistula is a result of trauma, infection, pelvic surgery, radiation treatment and therapy, malignancy, or inflammatory bowel disease.
