Stress Urinary Incontinence Urinary Incontinence | Behavioral: Behavioral Therapy Device: Intravaginal Pessary Device: Pessary combined with behavioral therapy | Phase 3 |
Women commonly have symptoms of stress urinary incontinence (leakage with physical stress such as coughing or sneezing) and urinary urgency or urge incontinence (leakage associated with the overwhelming urge to urinate). Non-surgical treatment is usually offered as first-line therapy, such as pelvic muscle exercises ("Kegel" exercises) or pessary use. A pessary is a small ring that fits inside the vagina. Pelvic muscle training and exercises may help incontinence by increased awareness and strength of the muscles that are used in holding the urethra closed. Pessary use may help incontinence by providing more support to the bladder and urethra. Both treatments can be helpful in reducing or eliminating incontinence, but it is not known which treatment is better. The study will compare the level of improvement with pelvic muscle exercises, pessary use, and a combination of both exercises and pessary.
Women with stress or mixed urinary incontinence will be randomly assigned to 1 of 3 groups: (1) pelvic muscle training and exercises; (2) pessary use; and (3) both exercises and pessary. Women in the exercises groups will have 4 visits over 8 weeks with a specially trained therapist for pelvic muscle training and exercises. Women in the pessary group will be fitted with a pessary to be worn continuously. Assessments will include questionnaires, bladder diary, and physical examination. Follow-up evaluations occur at 3 months, 6 months (by telephone only), and 1 year after initial treatment.
Comparisons: The level of improvement after treatment will be compared in the 3 groups. In addition, women in the 3 groups will record the number of accidental leakage episodes by bladder diary; and the frequency of those episodes will be compared in the 3 groups. Other aspects of health, including health-related quality of life, will be compared in the 3 groups.

Arm | Intervention/treatment |
---|---|
Experimental: Intravaginal Pessary
Pessary restores continence by stabilization of the proximal urethra and urethrovesical junction, facilitating pressure transmission to the proximal urethra.
|
Device: Intravaginal Pessary
Intravaginal pessary |
Experimental: Behavioral Therapy
Pelvic floor muscle training and exercise which includes strong contraction of the pelvic floor muscles to prevent incontinence by occluding the urethra and regular practice can improve pelvic muscle support.

Behavioral: Behavioral Therapy
Pelvic muscle training and exercises |
Experimental: Pessary combined with behavioral therapy
Combination of the explanations above.

- "Much Better" or "Very Much Better" on PGI-I at 3 Months [ Time Frame: Outcome was measured at three months following randomization. ]PGI-I, Patient Global Impression of Improvement, is a five-point scale that ranges from "not at all" to "very much better." Participants were considered a success if they responded "much better" or "very much better," or a failure if they responded otherwise.
- No Bothersome Stress Incontinence Symptoms at 3 Months [ Time Frame: Outcome was measured at three months following randomization. ]Success if participants answer either "no" or "yes" with a bother component of "not at all" or "somewhat" to all seven Urogenital Distress Inventory-Stress Incontinence Subscale items of the Pelvic Floor Distress Inventory, or a failure if they responded otherwise.
- "Much Better" or "Very Much Better" on PGI-I at 12 Months [ Time Frame: Outcome was measured at 12 months following randomization. ]PGI-I, Patient Global Impression of Improvement, is a five-point scale that ranges from "not at all" to "very much better." Participants were considered a success if they responded "much better" or "very much better," or a failure if they responded otherwise.
- No Bothersome Stress Incontinence Symptoms at 12 Months. [ Time Frame: Outcome was measured at 12 months following randomization. ]Success if participants answer either "no" or "yes" with a bother component of "not at all" or "somewhat" to all seven Urogenital Distress Inventory-Stress Incontinence Subscale items of the Pelvic Floor Distress Inventory, or a failure if they responded otherwise.
- 75% Reduction in Weekly Urinary Incontinence Episodes at 3 Months [ Time Frame: Outcome was measured at three months following randomization. ]Success if participants reported at least 75% reduction in frequency of incontinence episodes on 7-day bladder diary, a failure if they reported otherwise.
- 75% Reduction in Weekly Urinary Incontinence Episodes at 12 Months [ Time Frame: Outcome was measured at 12 months following randomization. ]Success if participants reported at least 75% reduction in frequency of incontinence episodes on 7-day bladder diary, a failure if they reported otherwise.
- Satisfaction With Treatment at 3 Months [ Time Frame: Outcome was measured at three months following randomization. ]Success if participant reported being "satisfied" on Patient Satisfaction Question (PSQ), a failure if they reported otherwise.
- Satisfaction With Treatment at 12 Months [ Time Frame: Outcome was measured at 12 months following randomization. ]Success if participant reported being "satisfied" on Patient Satisfaction Question (PSQ), a failure if they reported otherwise.
