Anterior Vaginal Prolapse (also known as cystocele)
This type of prolapse occurs when the wall between the vagina and the bladder stretches or detaches
from its attachment on the pelvic bones. This loss of support allows the bladder to prolapse or
fall down into the vagina.
Most women do not have symptoms when the anterior vaginal prolapse is mild. As it progresses outside
the opening of the vagina, the prolapsed bladder may not empty well which can lead to urinary frequency,
night time voiding, loss of bladder control and recurrent bladder infections. Strengthening pelvic muscles
may improve the support to the bladder and neighboring organs and reduce symptoms. In addition, women can
get temporary support by wearing a device called a vaginal pessary. It works much like a knee or ankle
brace would support a weak joint. When these efforts are inadequate surgery is available to elevate the
bladder and other internal organs to their proper position.
Posterior Vaginal Prolapse (also known as rectocele)
Weakening and stretching of the back wall of the vagina allows the rectum to bulge into and out of the
vagina. Most often, the damage to the back wall of the vagina occurs during vaginal childbirth, although
not everyone who has delivered a child vaginally will develop a rectocele. Mild rectoceles rarely cause
symptoms. However, straining with constipation puts significant pressure on the weak vaginal wall and can
further thin it out. Avoiding constipation may prevent progression and also reduce symptoms from the
rectocele. Some women may find benefit from pelvic floor muscle strengthening and vaginal pessaries.
When these low risk interventions are insufficient to relieve symptoms, surgery is performed to reinforce
the posterior vaginal wall. This picture shows what a rectocele looks like from the outside.
Uterine Prolapse
When the supporting ligaments and muscles of the pelvic floor that keep the uterus in the pelvis are
damaged, the cervix and uterus descend into and eventually out of the vagina. Often, uterine prolapse is
associated with loss of vaginal wall support (cystocele, rectocele). When the cervix protrudes outside
the vagina, it can develop ulcers from rubbing on underwear or protective pads. There is a risk that
these ulcers will bleed and become infected. This picture shows what uterine prolapse looks like from
the outside. As with other forms of prolapse, it is not until the uterine descent is bothersome that
treatment is necessary. Women who have uterine prolapse often report pelvic pressure, the need to sit or
lay down to relieve the discomfort, a sensation that their insides are falling out, difficulty emptying
their bladder and urine leakage. Strengthening the pelvic muscles with Kegel exercises, avoiding heavy
lifting, constipation, and weight gain may reduce the risk of progression of uterine descent. Additional
treatment options include pessary devices which provide support when worn or surgery.
Vaginal Prolapse after Hysterectomy
If a woman has already had a hysterectomy, the very top of the vagina (where the uterus used to be) can
become detached from its supporting ligaments. This can results in the tube of the vagina turning inside
out. This condition is also known as vaginal “vault†prolapse. Depending upon how extensively the top
of the vagina is turning inside out, one or several pelvic organs (such as the bladder, small and large
bowel) will prolapse into the protruding bulge. Symptoms depend on which organs are relapsing. When the
bladder is involved, women report difficulty in starting to urinate, and emptying their bladder well.
If it is the bowel then many report the need to push up the vaginal bulge and strain to have a bowel
movement. Skin sores may develop if the bulge is rubbing on pads or underwear. A pessary may provide
support for the bulge otherwise surgery is recommended. This is a picture of a vaginal vault prolapse.
Rectal Prolapse
The rectum is the name given to the last 6 inches of the colon. Like the vagina and uterus, the rectum is
normally securely attached to the bony pelvis by ligaments and muscles. Infrequently, the supporting
structures stretch or detach from the rectal wall which results in the rectum relapsing through the anus.
This looks like red, often donut shaped soft tissue coming through the anus. Early on, it is most often
noticed on the toilet after a bowel movement, and can be confused with a large hemorrhoid. Conditions
associated with straining such as chronic constipation or diarrhea, nerve and muscle weakness (paralysis
or multiple sclerosis) and advancing age are risk factors for rectal prolapse. Women with rectal prolapse
often report the following symptoms: pain during bowel movements, mucus or blood discharge from the
protruding tissue, loss of control of bowel movements, and soft, red tissue protruding from the anus. It
is very important to be clear in describing where the bulging tissue is coming from (opening of the anus or
the vagina) when you seek help as both conditions may be present simultaneously. Treatment for a rectocele
and rectal prolapse are different.
