Urinary incontinence (UI) affects up to 50% of adult populations and stress urinary incontinence (SUI) is the most common form of UI, accounting for approximately 60% of patients. Women are affected by SUI much more often than men. Urine leakage in women with SUI occurs on exertion or during tasks that increase pressure on the bladder such as sneezing or coughing. SUI has been shown to be a barrier to physical activity in women, and as such can contribute to the development of diseases and disorders associated with inactivity.

SUI appears to have many contributing factors such as structural damage (eg. tears in the pelvic organ supporting tissues), muscle weakness related to nerve injury or aging, or thinning of the urethral wall and/or its surrounding muscular sphincters. Currently the most common treatments for SUI are conservative therapy, which normally takes the form of exercise therapy provided by specialized nurses or physical therapists, and surgery, which is aimed at enhancing urethral support. Exercise therapy is effective, resulting in complete cure in 50% of cases, and surgery is effective for approximately 80% of patients but carries risks such as the development of urinary retention. It is currently not clear which treatment approach is better for which women.

Through the proposed research, the investigators aim to determine how to predict which patients will improve or be cured with exercise therapy such that surgery can be avoided. Specifically the investigators will determine what is different between patients in whom exercise therapy succeeds and in whom exercise therapy fails. The investigators will also determine whether physiotherapist-supervised training of the pelvic floor muscles before surgery improves surgical outcomes. The proposed research will enable us to better understand the female continence system and how it responds to physiotherapeutic intervention. It will help us to develop improved assessment procedures that can streamline patient management.

Primary Outcome Measures:
  • Change in International Consultation on Incontinence Questionnaire: Female Lower Urinary Tract Symptoms (FLUTS) [ Time Frame: 12 weeks before surgrey (TVT or TVT-O) to 12 weeks after surgery ]
    Changes in ICIQ FLUTS scores will be compared between treatment and control groups

  • Change in International Consultation on Incontinence Questionnaire - Short form score [ Time Frame: 12 weeks before surgery (TVT or TVT-O) to 12 weeks after surgery ]
    Changes in questionnaire scores will be compared between treatment and control groups

  • Change in pad weight on a standardized 30 minute pad test [ Time Frame: 12 weeks before surgery (TVT, TVT-O) to 12 weeks after surgery ]
    Change in pad weight (in g) on a standardized pad test will be compared between the treatment and control groups

Secondary Outcome Measures:
  • Change in International Consultation on Incontinence Questionnaire Quality of Life module score [ Time Frame: 12 weeks before surgery (TVT, TVT-O) to 12 weeks after surgery ]
    Changes in ICIQ-FLUTS QoL scores will be compared between the treatment and control groups.

Estimated Enrollment: 400
Study Start Date: November 2011
Estimated Study Completion Date: March 2018
Estimated Primary Completion Date: March 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Control
Participants in the control group will not receive therapist-supervised intervention. An exercise sheet briefly describing pelvic floor muscle exercises will be provided, as would be the standard practice from most physicians.
Experimental: Pelvic Floor Therapy
Participants in the experimental group undergo and assessment and treatment by a registered physiotherapist. Treatments will include two sessions of biofeedback training, therapist-assisted strengthening exercises, and will a prescribed home exercise program to strengthen their pelvic floor muscles.
Other: Pelvic Floor muscle strengthening exercises
Participants will attend regular physical therapy visits (weekly X 2 weeks, bi-weekly X 4 weeks, and continuing monthly) until the time of their surgery. they will then see the physical therapist for assessment, exercise and advice at 2 and 4 weeks after their surgery. During physical therapy visits, patients will receive two sessions of biofeedback training, and at each visit will work on strength and motor control exercises for their pelvic floor muscles.
