Fistulas

Gates of Vienna has a post on vaginal vesicle fistulas.

Ironically, I never saw a case, because most are due to long obstructed labour, and in certain parts of Africa, this is more common due to female circumcision.

Female circumcision is not done in the tribes of Zimbabwe, although some groups do circumcize boys at puberty...but I did see a few cases when I worked in Liberia
