Official title

The Amper Study: Amniotic Membrane for the Prevention of Mesh Exposure in Vaginal Reconstructive Surgery

Overview

This study evaluates the efficacy of adding a human amniotic membrane graft to polypropylene mesh surgery for pelvic prolapse and stress urinary incontinence. The goal is to assess improvements in tissue integration and the reduction of surgical complications

Interventions

  • Procedure Sacrospinous Hysteropexy with Mesh
    Sacrospinous Hysteropexy with polypropylene mesh
  • Procedure Retropubic Mid-urethral Sling (Bottom-Up)
    Retropubic mid-urethral sling (bottom-up approach) using polypropylene mesh for the treatment of stress urinary incontinence.
  • Procedure Transobturator Mid-urethral Sling (Out-In)
    Transobturator mid-urethral sling (out-in) using polypropylene mesh for the treatment of stress urinary incontinence.

Primary outcome measures

  • Number of Participants with Mesh exposure [Time frame: From enrollment through the end of the 12-month follow-up]

Eligibility criteria

Inclusion criteria

  • Pelvic organ prolapse (POP) stage II C or greater, defined as C ≥ +1, in women without prior hysterectomy and/or with a diagnosis of stress urinary incontinence seeking surgical treatment.
  • Ability to understand study information and provide written informed consent.
  • Availability for follow-up for a minimum of 12 months.

Exclusion criteria

  • Previous surgery with synthetic mesh (via vaginal or abdominal approach) for POP repair.
  • Known adverse reaction to synthetic meshes.
  • Unresolved or active chronic pelvic pain.
  • History of prior abdominal or pelvic radiation.
  • Contraindication to the planned surgical procedure.
  • Current pregnancy.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
