Brief Summary:
The primary aim of this double-blind, randomized clinical trial (RCT) is to test the hypothesis that the addition of a standardized technique of interpositional synthetic polypropylene mesh placement improves the one-year outcome of vaginal reconstructive surgery for pelvic organ prolapse compared to traditional vaginal reconstructive surgery without mesh.

Condition or disease Intervention/treatment Phase
Pelvic Organ Prolapse Uterine Prolapse Vaginal Prolapse Cystocele Rectocele Device: synthetic monofilament polypropylene mesh Not Applicable

Detailed Description:
Minimally invasive surgical procedures using mesh have rapidly developed in the field of pelvic floor reconstruction. Unfortunately, safety and efficacy data have lagged behind the technical advancements. No randomized controlled trials of different vaginal apical suspension procedures have been reported. The use of synthetic vaginal mesh has evolved due to the 20-30% recurrence rate for conventional pelvic reconstructive surgeries. This trial will examine synthetic monofilament polypropylene mesh use in vaginal reconstructive surgery for vaginal Stage II-IV prolapse.

Primary Outcome Measures :
  1. Number of Participants With Anatomic Cure at 3 Years [ Time Frame: 3 year ]

    3 different measures for Anatomic cure using POPQ measurements:

    1. POP-Q at Stage I or less* (POP-Q points Ba, Bp or C -1 or less);
    2. no prolapse beyond the hymen (Ba, Bp or C 0 or less);
    3. no prolapse beyond the hymen (Ba, Bp 0 or less) with adequate apical support above the midvagina (C to TVL/2 or less) No bulge symptoms using Pelvic Floor Distress Inventory, PFDI question 3; do you see or feel a bulge in the vaginal area with response of no.

    Patient Satisfaction using Patient Global Impression of Improvement with response of very much better or much better

Secondary Outcome Measures :
  1. Bothersome Dyspareunia [ Time Frame: 3 year ]
    Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire question 5 response of usually or always and tracked resolution, persistence, de novo dyspareunia
