Adjustable Continence Therapy (ACT) Device for the Treatment of Female Stress Urinary Incontinence (ACT)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00113555

Brief Summary:

The purpose of this study is to evaluate the safety and effectiveness of a minimally invasive surgical procedure in up to 160 implanted female patients in which two adjustable balloons (one on each side of the urethra) are implanted to treat urinary stress incontinence.

The results will be analyzed to demonstrate the effects of the device as well as its associated risks. Therapeutic success will be based on whether the patients demonstrate at least a one-grade (mean) reduction in the Stamey score at 12 months.

Condition or disease Intervention/treatment Phase
Urinary Incontinence Device: ACT (Adjustable Continence Therapy) Not Applicable

Detailed Description:
This is a multi-center, prospective, non randomized clinical trial comparing baseline data to the 12 month data. Urodynamic testing, pad weights and a direct visual stress test will be used to determine success along with the Stamey score.

Primary Outcome Measures :
  1. Change of Stamey Grade From Baseline to 12 Months. [ Time Frame: Baseline to 12 months ]

    The Stamey grade classifies the severity of stress incontinence in four possible grades from 0-3. Grade 0: no leaking, Grade 1: loss of urine with sudden increases of abdominal pressure: e.g. coughing, sneezing or laughing, Grade 2: loss of urine with lesser degrees of stress: e.g. walking or standing up, and Grade 3: loss of urine without any relation to physical activity or position, e.g. while lying in bed.

    The primary end point at 12 months is a mean change in Stamey Grade from baseline of greater than or equal to -1.

Secondary Outcome Measures :
  1. Incontinence Quality of Life (IQoL) Questionnaire [ Time Frame: Baseline to 12 months ]
    Change on Incontinence Quality of Life (IQoL) Questionnaire from baseline to 12 months. 0 being lowest quality of life, 100 being highest quality of life.

  2. Incontinence Impact Questionnaire (IIQ-7) [ Time Frame: Baseline to 12 months ]
    Incontinence Impact Questionnaire (IIQ-7) change from baseline to 12 months. Scores range from 0-100. 0 being impact from incontinence, 100 being most impacted from incontinence.

  3. Urinary Distress Inventory (UDI-6) [ Time Frame: Baseline to 12 months ]
    Change on Urinary Distress Inventory (UDI-6) questionnaire from baseline to 12 months. 0 being not distressed, 100 being very distressed.

  4. Number of Incontinence Episodes Per Day (Voiding Diary) [ Time Frame: Baseline to 12 months ]
    Change in Number of Incontinence Episodes Per Day from baseline to 12 months. 0 being the best.

  5. Number of Pads Changed Per Day (Voiding Diary) [ Time Frame: Baseline to 12 months ]
    Change in Number of Pads Changed Per Day from baseline to 12 months. 0 pads changed a day being the best.

  6. Provocative Pad Weight [ Time Frame: Baseline to 12 months ]
    Change in weight of pads (gm) from baseline to 12 months. 0 gm pad weight being the best.
