The document discusses surgical techniques for repairing posterior compartment prolapse, including traditional posterior colporrhaphy, site-specific defect repair, and transanal vs transvaginal approaches. It reviews studies comparing success rates, anatomical outcomes, and rates of dyspareunia, constipation, and other functional outcomes between techniques. Key points emphasized are the importance of levatorplasty for advanced prolapse and aggressive reattachment of the posterior vaginal wall to the uterosacral ligaments for high rectoceles or those with an enterocele.
