Pelvic organ prolapse occurs when the pelvic muscles and ligaments are weakened, making them unable to hold the pelvic organs in place. The organs can then drop down into the pelvic area.

Women with prolapse often have a sense of heaviness in the vagina or pelvis. They may complain of feeling that they are “sitting on a ball”, or notice a bulge or mass protruding from the vaginal area while showering. Sometimes this feeling of heaviness or bulging is experienced more towards the end of the day, after working or standing all day. Other symptoms include discomfort during intercourse, urinary incontinence and bowel problems.

Some women may attempt to push the prolapsed organ back in to help when urinating, but may notice that the pressure is reduced on its own when they lie down at night. There are several different types of pelvic organ prolapse, with different names depending on the organs involved.

What causes pelvic organ prolapse?

Pelvic organ prolapse occurs when the muscles in the pelvic floor are stretched or aren’t strong enough to hold the pelvic organs in their correct position. It isn’t a life-threatening condition, but can cause pain and discomfort and have a major impact on your day-to-day quality of life.

Things that can cause the muscles in the pelvis to become stretched or weakened include:

• Pregnancy and childbirth
• Aging and menopause
• Obesity
• Fibroids or pelvic tumors
• Long-term (chronic) coughing
• Long-term (chronic) constipation
• Lifting heavy objects
• Certain genetic conditions
• Prior pelvic surgery
• Some neurological conditions or spinal cord injuries

The main types of pelvic organ prolapse are:

Bladder prolapse – Cystocele occurs when the bladder, which stores urine, slips down and pushes against the front of the vagina.

Rectum prolapse – Rectocele occurs when the rectum bulges into the back of the vagina.

Urethra prolapse – Urethrocele occurs when the urethra, which transports urine from the bladder and out of the body, slips and pushes against the lower part of the front of the vagina.

Vaginal vault prolapse – Vaginal vault prolapse occurs when the top of the vagina falls in on itself. This may only happen if a woman has had a hysterectomy – an operation to remove the uterus.

Small bowel prolapse – Enterocele occurs when the small intestine drops down between the back of the vagina and the rectum. This may occur at the same time as prolapse of the uterus or rectum.

Uterus prolapse – Uterine prolapse occurs when the uterus (womb) drops down into the vagina.

Your doctor will assess which type of prolapse you may have. It is possible to have more than one type at the same time.

There are different treatment options available for pelvic organ prolapse. Your doctor will be able to help you find the best solution for you, according to the type and cause of the prolapse. They will also take into account your plans for the future, including whether you would like to become pregnant.

Treatment may start with non-surgical options such as Kegel exercises, a pessary (device worn in the vagina for support), estrogen supplementation, electrical stimulation or biofeedback.

Kegels are exercises that can help strengthen your pelvic floor muscles. In mild cases of uterine prolapse, they may the only treatment needed. However, for them to be effective, they need to be done daily.

Vaginal pessary is a rubber or plastic device used to support the pelvic floor and the prolapsed organ. A doctor or healthcare professional will insert and fit the pessary, which must be cleaned frequently and removed before sexual intercourse.

Estrogen replacement therapy may help to limit any further weakening of the muscles and connective tissues that support the uterus, bladder and rectum. Ask your doctor for more information about potential benefits, risks and complications.

You should discuss all treatment options available to you with your doctor.

If you need surgery to repair your pelvic organ prolapse, the treatment may involve using your own tissue or a graft.
