a ring of rubber, plastic, or metal in which the cervix rests; designed to support the uterus and to correct prolapse of that organ.
Synonym(s): doughnut pessary


(pes′ă-rē) [L. pessarium, suppository]
A device inserted into the vagina to function as a supportive structure for the uterus. A pessary may be inserted to treat symptomatic uterine displacements. After manually repositioning the uterus, the physician inserts the appropriate-size device; a woman should not feel a well-fitted pessary. Pessaries should be removed and cleaned frequently; however, this requires manual dexterity and is difficult for elderly patients. Use of an antibacterial cream or gel will help decrease odor. Unless discomfort arises, the device is removed about 6 weeks later. If relief and anteversion occur, no further treatment is necessary. If not, the pessary is reinserted for another 6 weeks.

cup pessary

A pessary that has a cup-shaped hollow that fits over the os uteri. It is used to treat a mild uterine prolapse.

diaphragm pessary

A cup-shaped rubber pessary used as a contraceptive device.

Nager made the following comments about the other types of pessary, which he turns to when the ring pessary does not work:
The gellhorn, which is shaped like a diaphragm with an elongated stem in the center on the convex side, is the pessary to use when the ring pessary will not stay in and there is a need for the pessary to occupy 3-dimensional space.
The donut pessary, which is much more massive than the ring pessary, will often stay in place when a ring pessary will not, and may be especially useful in women with a short vaginal vault.
