The goal of this multicenter observational study is to collect data prospectively of patients with pelvic organ prolapse undergoing ventral mesh rectopexy (as well as rectoceles, entero-/sigmoidoceles/ intussusception/ rectal prolapse or combined) by laparoscopy or robotic surgery and to evaluate the longterm functional outcomes. Secondly complications (mesh erosions, recurrence, reoperations) are evaluated. Following main questions will be analysed - other can follow in consultation with the collaborative 1. Is VMR the technique of choice for treatment of rectoceles? Functional results - recurrence - mesh related complications 2. Has a perineal descent an impact on the functional outcome of ventral mesh rectopexy perfored for external rectal prolaps, internal rectal prolaps, rectocele, enterocele, sigmoidcele or combined pelvic organ prolapse?
