What is the most common cause of a fistula in a third world country?

Question

I am researching fistulas for a university project and was wondering if anyone knew? And also if they are curable?

Answer 1

Trauma during child birth. Many times the bladder/urethra will have a fistula that will drain urine through the v****a.  

Answer 2

Poor medical care during childbirth, especially in cases in which the woman giving birth is very young because she was forced into marriage at a young age.
