Vaginal Native Tissues Repair for Pelvic Organ Prolapse

The aim of the study is to assess at one year the effectiveness of the vaginal patch plastron in comparison of the anterior colporraphy through a combined definition of success: anatomic and functional.

Pelvic organ prolapse is usually the result of loss of pelvic support. It is widely accepted that 50% of women after 50 years old will develop prolapse, evaluated through the POPQ Classification . Pelvic organ prolapse cause significant psychological distress and negatively affect quality of life. Among the surgery for prolapse, the cystocele cureis is the most frequent (67.7%). Native tissue cystocele repairs is the cornerstone of prolapse surgery especially since the learned societies (Food and Drug Administration, Haute Autorité de Santé, Collège National des Gynécologues-Obstétriciens Français) warned clinicians and patients about serious mesh related complications. In France, 41.5% of vaginal cystocele repair are with native tissue. The main surgeries are anterior colporraphy and vaginal patch plastron, used in routine in our center with re-intervention rates less than 4% at one year. Rate of success of native tissue cystocele repair are heterogeneous, depending on the design of studies and definition of outcomes. A prospective study find a success rate at 35% of the anterior colporraphy based on a combined definition, anatomic and functional as recommended recently. However the definition of anatomic was strict (POPQ\<2), while it seems that the best definition of anatomic success is "no prolapse among the hymen", that is to say aAa and Ba points \<0.

We think that the vaginal patch plastron will have a better anatomic and functional success comparatively to the anterior colporraphy as it corrects median cystoceles by a vaginal strip as well as lateral cystoceles by the bilateral paravaginal suspension.

The description of the two surgeries will be standardized between all the surgeons. We will compare the anterior colporraphy consisting in bladder median support by retensioning Halban fascia with colpectomy to the vaginal patch plastron consisting in making a vaginal strip attached to the bladder combined with suspension by fixation of the vaginal strip to the tendinous arch of the pelvic fascia.

Patients will be blind of their surgery. They will have a follow-up visit 45 days after the surgery to evaluate the post- operative complications according to the Clavien-Dindo classification. They will have phone call at 4 and 8 months after the surgery to make sure they've not suffered for complications. At last, they will have a follow-up visit 1 year after the surgery by an independent assessor blind of the surgery to evaluate the primary outcome (anatomic and functional success).
