What is a vaginal fistula?
A fistula is a passage or hole that has formed between:
- Two organs in your body.
organ in your body and your skin.
A fistula that has formed in the wall of the vagina is called a
- A vaginal fistula that opens into the urinary
tract is called a vesicovaginal fistula.
vaginal fistula that opens into the rectum is called a rectovaginal fistula.
- A vaginal fistula that opens
into the colon is called a colovaginal fistula.
- A vaginal fistula that opens into the small bowel
is called a enterovaginal fistula.
What causes a vaginal fistula?
A vaginal fistula starts with some kind of tissue damage. After
days to years of tissue breakdown, a fistula opens up.
A vaginal fistula sometimes happens after:
- Surgery of the back wall of the vagina, the
perineum, anus, or rectum. Open hysterectomy is linked to most vesicovaginal
- Radiation treatment for pelvic cancer.
- A period of
inflammatory bowel disease (including
Crohn’s disease and
ulcerative colitis) or
- A deep tear in the
perineum or an infected
episiotomy after childbirth.
In areas where women have no health care nearby,
vaginal fistulas are much more common. After days of pushing a baby that does
not fit through the birth canal, very young mothers can have severe vaginal,
bladder, or rectal damage, sometimes causing fistulas.
What are the symptoms?
A vaginal fistula is usually painless. But a fistula lets urine or feces
pass into your vagina. This is called incontinence. And it can cause
soiling problems that you cannot control.
- If you have a vesicovaginal fistula, you most
likely have fluid leaking or flowing out of your vagina.
- If you
have a rectovaginal, colovaginal, or enterovaginal fistula, you most likely
have foul-smelling discharge or gas coming from your vagina.
genital area may get infected or sore.
How is a vaginal fistula diagnosed?
Your symptoms are the most clear signs of a vaginal fistula. Your
doctor will want to talk about your symptoms and about any surgery, trauma,
or disease that could have caused a fistula. For a physical exam, your doctor
will use a
speculum to look at the vaginal walls. You may have
other tests, such as:
- The use of dye in the vagina (and maybe the
bladder or rectum) to find all signs of leakage.
- Urinalysis to
check for infection.
- Blood test (complete blood count) to check for
signs of infection in your body.
How is it treated?
If you have a vaginal fistula, you will most likely need surgery
to repair it. Before surgery, your doctor will see whether the tissue is
healthy or needs to heal first.
- You may need medicine or wound care to heal
the tissue before surgery.
- If you have inflammatory bowel disease,
your doctor will not do surgery during a symptom flare.
- If you
have a large rectovaginal fistula, you may first have a
colostomy. This is to keep the fistula clear for the
surgery. After the fistula repair heals, the colostomy is taken out.
After fistula repair surgery, be sure to follow your doctor’s
instructions. See your doctor right away if you have signs of infection, such
as a fever, tenderness, swelling, or redness.
