Primary Outcome Measures:
  • Improvement in patient continence status [ Time Frame: Within the first two years after surgery ]

Enrollment: 55
Study Start Date: September 2005
Study Completion Date: November 2009
Primary Completion Date: May 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: The AMS Male Transobturator Sling System
    The AMS Male Transobturator Sling System was developed to treat urinary stress incontinence in men resulting from intrinsic sphincter deficiency (ISD) secondary to radical prostatectomy. The Male Transobturator Sling System procedure is minimally invasive and consists of using two single-use needle passers and passing them through two small incisions over the obturator foramen. The needles are pushed in an arc through the tissue and exited at a perineal incision. Once the passers are through the perineal incision, the Sling System mesh arms are attached to the needles which are then pulled back through the needle track to their points of origin over the obturator foramen. The Sling System is subsequently tensioned and all incisions are closed.
    Device: AdVance Male Sling
    A transobturator sling for the treatment of post-prostatectomy incontinence
    Other Names:
    • Male TO
    • transobturator sling
    • suburethral sling
    • retrourethral sling
Detailed Description:

A multi-center study conducted under a common implant and follow-up protocol. The study will collect pre-operative urologic testing, medical history and subject quality of life (Incontinence Quality of Life Questionnaire). Intra-operative procedural data will be collected.

Pad weight and incontinence severity rating (using the ICIQ survey) will be used to characterize continence status.

Post-operative complications, urologic testing, and subject quality of life will be collected at six weeks and three, six, 12, and 24 months.
