The goal of this study is to evaluate whether adding perineoplasty is, in comparison to performing vaginal prolapse surgery without adding perineoplasty, superior with respect to efficacy and cost-effectiveness and non-inferior with respect to morbidity, in patients undergoing vaginal surgical correction of pelvic organ prolapse at 24 months after surgery.
