Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To assess to the non-inferiority of the retropubic Neomedic Knotless Incontinence Mesh (KIM) sling compared to the Gynecare Tension-free Vaginal Tape (TVT) Exact sling.

Participants: Women 21 years or older with a diagnosis of stress urinary incontinence (SUI) or mixed urinary incontinence (MUI) with objective evidence of SUI planning surgery for stress urinary incontinence.

Procedures (methods): Patients will be randomized to receive either the Gynecare TVT Exact sling or the retropubic Neomedic KIM sling. Patients will be followed for 1 year postoperatively.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Midurethral slings (MUS) are recognized as a minimally invasive treatment of SUI. The retropubic route of MUS placement has a cure rate of 89.1% with long term subjective cure rates ranging from 51-88%. The Neomedic Knotless Incontinence Mesh (KIM) sling is a tension-free macroporous monofilament polypropylene knotless mesh designed to be resistant to elongation and deformation over time. The KIM sling also offers a reusable trocar, which results in less waste and cost- savings. KIM sling trocars are available for the retropubic route or trans-obturator (TOT) route.

While studies have been performed comparing the TOT approach of the KIM sling to other slings, no studies have been performed to date with the retropubic (RP) approach. The RP and TOT approaches to MUS have been shown to be equivalent in the treatment of SUI. Since the same mesh material of the KIM sling is used for both the TOT and RP approach, it can be hypothesis that the RP route would show similar treatment success rates.

A type 1 macroporous (\> 75um) polypropylene mesh is the most appropriate material for vaginal implantation. However, literature has suggested that the design and weave of synthetic mesh material can also have a significant effect on efficacy and safety; therefore, the novel design of the KIM may be beneficial to reduce complications. If there is similar efficacy with the RP approach of the KIM sling to the TVT Exact, there will be benefit of reduced costs and the potential for less complications. With this study, the objective is to show non-inferiority of the KIM sling to the Gynecare TVT Exact.
