Surgical management of posterior vaginal wall prolapse: an evidence-based literature review

The aim of this review is to summarize the available literature on gynecological management of posterior vaginal wall prolapse. A MEDLINE search and a hand search of conference proceedings of the International Continence Society and International Urogynecological Association was performed. Two randomized trials demonstrated that the transvaginal approach to rectocele is superior to the transanal repair in terms of recurrent prolapse. The traditional posterior colporrhaphy with levator ani plication was largely superceded by fascial repairs with similar anatomic success rates but favorable functional outcome. The midline fascial plication may offer a superior anatomic and functional outcome compared to the discrete site-specific fascial repair. Controlled studies are necessary to evaluate whether a sacrocolpopexy combined with posterior mesh interposition is an effective alternative to the transvaginal repair. There is currently no evidence to recommend the routine use of any graft and complications such as mesh erosion, infection, and rejection have to be considered.
