Study Details

Study Description

Brief Summary

Pelvic organ prolapse is a common problem. A lot of women have surgery for prolapse. The recurrence rate op pelvic organ prolapse after surgical treatment is high. Placement of a mesh aims at reducing the recurrence rate, but mesh implants can cause complications.

This study is designed to determine the effectiveness of one type of mesh (tensionfree vaginal mesh; Prolift), compared with the standard prolapse surgery. A secondary objective is to track the complications of both procedures.

Condition or Disease Intervention/Treatment Phase
  • Device: Tensionfree vaginal mesh kit (Prolift)
  • Procedure: classic vaginal prolapse surgery (fascia plication)
N/A

Detailed Description

Patients with recurrent prolapse after surgery can participate in this study. A total of 194 women will be included. At random 97 patients undergo a standard prolapse operation and 97 patients undergo an operation with the mesh. Evaluation will take place during surgery, at the postoperative visit after six weeks, and after six months and twelve months. Quality of life, degree of vaginal prolapse, subjective effectiveness, safety and incidence of complications will be evaluated.

An amendment to the original study has been approved by the Ethical Committee to examine long term outcome of this RCT at 7 years. This study was completed in december 2015.

  • Outcome Measures

    Primary Outcome Measures

    1. Prolapse by "Pelvic Organ Prolapse Quantification System" (POP-Q), at 12 Months [12 months]

      Number of participants with anatomic failures defined as "Pelvic Organ Prolapse" (POP) stage II or higher

    Secondary Outcome Measures

    1. Mesh Exposure at 12 Months [12 months]

      cumulative number of patients with mesh exposure at 12 months (if diagnosed at 6 weeks or 6 months and treated, the exposure is calculated at 12 months, even if the exposure was not there anymore)

    2. "Patient Global Impression of Improvement" (PGI-I) at 12 Months [at 12 months]

      Number of participants with much to very much improvement compared to baseline

    3. Bulge Symptoms [12 months]

      Bulge symptoms defined as Prolapse domain score of the "Urogenital Distress Inventory" (UDI) at 12 months. Scores range from 0 (least/no bother) to 100 (maximum bother)
