Although laparoscopic sacrocolpopexy (LscASC) has been demonstrated to yield comparable success rates to abdominal sacrocolpopexy (93-99%) for the surgical treatment of pelvic organ prolapse, it has not been widely adopted due to the increased operating time and steep learning curves associated with laparoscopic suturing and knot-tying. For these reasons, robotic systems have been advocated for this technique. The objective of this study is to conduct a prospective single-blinded randomized controlled trial of robotic assisted versus traditional LscASC in the treatment of patients with apical vaginal prolapse stages II-IV (prolapse from 1 cm proximal to the hymen to all points distal).
