Trial Outcomes & Findings for A Randomized Controlled Trial of the Uresta Continence Pessary (NCT NCT01284244)

Results Overview

A pad test is an objective measure of urine loss. With a full bladder, while wearing a pad, the participant completes five repetitions of the following physical activities: coughing, step climbing, heel bounce, standing from a sitting position and walking 50 yards. The weight of the pad is then determined. The primary outcome variable will be the achievement of a 50% reduction in the pad weight before and after device placement. This figure is obtained from the study by Farrell et al, where pad weight decreased from 20 grams to 9 grams with the use of the Uresta device.

Measure	Uresta Uresta pessary: Participants randomized to the Uresta group will be fitted with device before immediately before performing the pad test. The Uresta pessary is made of medical grade rubber that has been extensively tested for safety. It is bell-shaped, with a narrow tip that allows for easy insertion into the vagina in a similar fashion to a tampon. The device can be easily inserted, and removed by a patient for use when needed. The Uresta comes in 3 sizes. Fitting starts with insertion of the smallest size. If urine leakage continues with valsalva or a cough stress test, it can be replaced by one size larger, until leakage is stopped. If the device prevents the patient from being able to void or is uncomfortable due to its size, the smaller size is replaced. Following the pad test, the participant will be given the opportunity to keep the device for continued use, or remove it if desired.	Silastic Vaginal Ring Silastic ring: The silastic ring is a plastic flexible ring similar to that used to administer vaginal estrogen (Estring). It is well tolerated and would not contain any medications. Immediately before performing the pad test, it would be placed high in the vagina, away from the urethra. It would be removed immediately after the pad test. Draping will conceal from the patient which device was inserted.
