Group/Cohort Intervention/treatment
AMS 800 Artificial Urinary Sphincter Recipients
Adult males with moderate to severe primary stress urinary incontinence (as assessed by a baseline pad weight test) due to ISD who meet the indications for surgical correction of urinary incontinence.
 Device: AMS 800 Artificial Urinary Sphincter
The AMS 800 Artificial Urinary Sphincter (AUS) is an implantable, fluid filled, solid silicone elastomer device used to treat stress urinary incontinence due to reduced urethral/bladder outlet resistance (intrinsic sphincter deficiency). It is designed to restore the natural process of urinary control. The device simulates normal sphincter function by opening and closing the urethra under the control of the patient.


Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of subjects with reduction in 24 hour pad weight test at 12 months [ Time Frame: 12 months ]
    Number of subjects achieving 50% reduction or greater in baseline urinary incontinence as measured by 24-hour pad weight test at 12 months post device activation


Secondary Outcome Measures :
  1. Incidence of safety parameters [ Time Frame: 3 months, 6 months and 12 months ]
    Incidence of safety parameters at 3 months, 6 months, and 12 months. Safety parameters include device and/or procedure related adverse events, revision rates, and serious adverse events

  2. Number of subjects achieving ≥ 50% reduction in 24 hour pad weight test at 6 months [ Time Frame: Device Activation and 6 months ]
    Number of subjects achieving ≥ 50% reduction in urinary incontinence as measured by 24-hour pad weight test at device activation and 6 months post device activation compared to baseline

  3. Number of subjects achieving ≥ 75% reduction in 24 hour pad weight test at 6 and 12 months [ Time Frame: Device Activation, 6 months, and 12 months ]
    ≥ 75% reduction in urinary incontinence as measured by 24-hour pad weight test at device activation, 6 months, and 12 months post device activation compared to baseline

  4. Number of pads per day [ Time Frame: 3 months, 6 months, and 12 months ]
    Reduction in # of pads per day at 3 months, 6 months and 12 months post-device activation compared to baseline
