Rationale: Pelvic organ prolapse is highly prevalent in the female population. The incidence of pelvic organ prolapse increases with age, so the longer life expectancy of women may cause pelvic organ prolapse to become an even more major health issue. The recurrence rate of pelvic organ prolapse after surgical treatment is high. The recurrence rate of the anterior vaginal wall prolapse after an anterior colporrhaphy is 30%-45%. The posterior vaginal wall prolapse recurrence rate after a posterior colporrhaphy is 12-25%. This emphasizes the clinical need for improvement of the surgical techniques currently used. Placement of a mesh aims at reducing the recurrence rate (2-11%).
