Ring pessaries are silicone rings that either come with or without additional support.
They can be fitted for any type of pelvic organ prolapse but may be less successful if the perineum is unable to provide enough support such that the ring is poorly retained or if the upper vagina is narrowed by previous surgery e.g. hysterectomy. Sexual activity is possible with the pessary in place as the vaginal space is not filled by the device although either partner may find sexual intercourse uncomfortable and may wish to remove it before sex. Self-management can commonly involve a ring pessary.
Before pessary use is initiated, a thorough assessment should rule out contraindications — such as active vaginal or pelvic infection, severe ulceration, or inability to comply with follow‑up — and consider adjunctive measures like pelvic floor muscle training and optimisation of vaginal health with topical oestrogen where appropriate.
Pessary use is part of a shared decision‑making process and can be continued long‑term if effective and well tolerated, enabling many women to maintain normal daily activities with reduced prolapse symptoms. The POGP guidelines emphasises the importance of assessing fit and symptom relief during the initial fitting and during scheduled reviews, and adjusting size or type if necessary to achieve optimal comfort and retention.

Silicone rings are also available from Mediplus in a variety of sizes. These are more pliable than the PVC pessaries and as they can fold, are often easier to insert and remove so are useful for a woman who is self-managing. Silicone pessaries are more expensive to buy but can be washed and re-inserted on many occasions. [1]
