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.
The pessary is similar to the outer ring of a diaphragm. It can be placed temporarily or permanently and must be fitted by a physician. Most pessaries can be worn during intercourse.
An occlusive pessary is generally used in combination with spermicide as a contraceptive; please refer to cervical cap for more details.
