A pessary is a small plastic or silicone medical device or form of pharmaceutical preparation which is inserted into the vagina or rectum and held in place by the pelvic floor musculature.
A therapeutic pessary is used to support the uterus, vagina, bladder or rectum. A pessary is most commonly used to treat prolapse of the uterus. It is also used to treat stress urinary incontinence, a retroverted uterus, cystocele and rectocele. It is similar to the outer ring of a diaphragm. It can be placed temporarily or permanently and must be fit by a physician. Most pessaries can be worn during intercourse.
A physician will provide instruction for the proper care of a pessary. Some patients are instructed to take out, clean with soap and water, and reinsert the pessary every few days or weeks. Others will need to visit the doctor for cleaning.
A pessary can cause increased vaginal discharge, vaginal irritation, ulceration, bleeding, and dyspareunia (painful intercourse for the male or female). Cervical cancer is more likely in older women with a prolonged history of pessary use.
An occlusive pessary is generally used in combination with spermicide as a contraceptive; please refer to cervical cap for more details.
