Is this trial a fit for you?

Likely a good fit

Women with pelvic organ prolapse stage II C or higher, seeking surgical treatment, and without a prior hysterectomy or with stress urinary incontinence, who can consent and commit to at least 12 months of follow-up.

Probably not a fit

Individuals with prior synthetic mesh surgeries for POP, active chronic pelvic pain, radiation history, or contraindications to the planned procedures may not benefit.

What this trial studies

This interventional study evaluates the safety and potential benefits of incorporating a human amniotic membrane graft with polypropylene mesh during sacrospinous hysteropexy and mid-urethral sling procedures. Participants have pelvic organ prolapse stage II or higher and may have or be at risk for stress urinary incontinence, and are followed for at least 12 months. The trial will look at tissue integration and the rate of surgical complications to see if the graft improves outcomes. Recruitment is limited to a center in Buenos Aires, Argentina, led by Hospital General de Agudos J. M. Penna. The study does not list a formal phase or comparative randomization in the provided information.

Why it matters

Potential benefit: If successful, patients may experience better tissue healing and fewer mesh-related complications after pelvic prolapse and incontinence surgeries.

How similar studies have gone: Some previous approaches using grafts with mesh have shown mixed or limited evidence; this study explores amniotic membrane grafting in this surgical context, representing a relatively novel application.
