A pessary is used for incontinence, not for infrequent urination, so it will not help that condition. It is used as an alternative to surgery for women with prolapse or incontinence.
Many women will experience incontinence or prolapse as they age. While surgery is one option to fix the problem, it is not always the best option, as stated by the National Institute of Health. Women who plan to have children or are too weak or old for the surgery may consider a pessary. A pessary is a device that the woman inserts in order to ease pressure on the bladder or uterus. The device will be fitted by a doctor after the woman has chosen it as an option.
