Pelvic organ prolapse (POP) affects approximately half of all women over age 501. The most common type of POP is anterior vaginal wall prolapse. Symptoms associated with POP include: voiding dysfunction, defecatory dysfunction and vaginal bulge symptoms. Treatments for pelvic organ prolapse include among other options, vaginal pessary or surgery. Several studies have documented improved vaginal bulge symptoms in women treated with a pessary2,3,4; however, data are sparse regarding the effect of pessaries on lower urinary tract symptoms, specifically with regard to over active bladder symptoms.
