Obstetric fistulas are the only preventable fistulas. These can be prevented with good prenatal and childbirth care and by avoiding pregnancy in very young girls.
A fistula is an abnormal passageway between two areas where no passageway should exist. So there can be a fistula that forms between the rectum and the vagina. Rectal-vaginal fistulas require surgery to repair.
Fistulas are categorized by the number of openings they have and whether they connect two internal organs or open through the skin.

There can be several different causes of vaginal itching. Some of the most common causes are using different soaps or laundry detergent. Additionally, super tight underwear that is not made of cotton can cause vaginal problems.
Usually a fungal infection, sometimes bacterial.
One of the most common causes of vaginal lesions are tampons - as tampons absorb vaginal moisture and rough fribes (especially rayon) cause friction against vaginal walls, tampons can cause lesions to vaginal walls...which is one reason why tampons are linked with increased menstrual bleeding and TSS. Vagonal lesions can also be caused by some forms of spermicidal gels, vaginal infections such as yeast infections where skin is damaged by the infection itself or by itching, sex or other forms of sexual activity with vaginal penetration, and sexual examinations.
