The primary aim of this clinical trial is to compare treatment success for two minimally invasive surgical procedures to treat stress urinary incontinence in women. These procedures are called mid-urethral slings. The secondary aims of the trial are to compare other outcomes for the two surgical procedures, including quality of life, sexual function, satisfaction with treatment outcomes, complications, and the need for other treatments(s) after surgery. Follow-up will be a minimum of two years.

Condition Intervention Phase
Urinary Incontinence Procedure: retropubic mid-urethral sling (TVT) Procedure: transobturator mid-urethral sling (TVT-O and the Monarc) Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

Primary Outcome Measures:
  • Objective Treatment Success at 12 Months [ Time Frame: 12 months ]

    Objective treatment success: negative stress test, negative pad test, and no retreatment for stress urinary incontinence (SUI) including behavioral, pharmacologic or surgical procedures

    A provocative stress test standardized to volume and position is performed for direct observation of urine leakage. Observed urine loss from the urethra coincidental with the Valsalva maneuver or cough is a positive test; a negative test indicates no urine loss. Pad testing quantifies the amount of urine involuntarily lost and is used to reflect everyday incontinence; it is negative if loss is <15g/24 hrs.

  • Subjective Treatment Success at 12 Months [ Time Frame: 12 months ]
    Absence of self-reported symptoms of stress-type urinary incontinence, as assessed with the use of the Medical, Epidemiological and Social Aspects of Aging (MESA) questionnaire (responded never to all 9 MESA questions), no leakage recorded in a 3-day voiding diary and no retreatment for stress incontinence including behavioral, pharmacologic or surgical treatment.

Secondary Outcome Measures:
  • Patient Satisfaction at 12 Months [ Time Frame: Follow-Up ]
    Patient satisfaction was assessed at the 12 month visit with the questions, "how satisfied or dissatisfied are you with the result of bladder surgery related to urine leakage?" Possible responses were completely satisfied, mostly satisfied, neutral, mostly dissatisfied, and completely dissatisfied. Completely and mostly satisfied were reported as "satisfied" and neutral, most dissatisfied and completely dissatisfied as "not satisfied".

  • Change in Quality of Life From Baseline to 12 Months [ Time Frame: Baseline - 12 months ]
    Scores on the Incontinence Impact Questionnaire range from 0 to 400 with higher scores indicating greater impact. The scores are changes from baseline to the 12 month visit (baseline - 12 months).

  • Bother as Measured by the Urogenital Distress Inventory (UDI) at 12 Months [ Time Frame: 12 months ]
    Urogenital Distress Inventory (UDI) scores range from 0 to 300 with higher scores indicating greater distress. Scores are changes from baseline to the 12 month visit (baseline - 12 months)

Arms Assigned Interventions
Active Comparator: 1
retropubic mid-urethral sling (TVT) The specific TVT used was the Tension-free Vaginal Tape (Gynecare)
Procedure: retropubic mid-urethral sling (TVT)
This trial is a comparison of two types of mid-urethral slings. The retropubic mid-urethral mesh sling is used for treatment of stress incontinence; this procedure was less invasive than the fascial sling procedures that were reference standards at the start of the study. Specifically, a synthetic tape is passed transvaginally at the midurethral level through the retropubic space.
Active Comparator: 2
transobturator mid-urethral sling (TVT-O and the Monarc) Two transobturator slings were used: the Tension-free Vaginal Tape Obturator (Gynecare), which is placed starting inside the vagina and coming out through the obturator foramen ("in-to-out") or the Monarc (American Medical System), which is placed starting in the groin area, passing through the obturator foramen, and then into the vagina ("out-to-in").
Procedure: transobturator mid-urethral sling (TVT-O and the Monarc)
This trial is a comparison of two types of mid-urethral slings. The transobturator mid-urethral sling is used for treatment of stress incontinence; this procedure was developed to minimize the potential for bladder and bowel injuries associated with the retropubic sling, since the sling is passed through the obturator canal, avoiding the pelvic organs in the retropubic space.
