Structural Failure Sites in Anterior Vaginal Wall Prolapse: Identification of a Collinear Triad

Abstract

(Abstracted from Obstet Gynecol 2016;128:853–862) The most common form of pelvic organ prolapse and the most frequent site of operative failure is cystocele formation (anterior vaginal wall prolapse). Potential fascial and muscular failure factors (anatomic sites of injury) identified as causal factors contributing to cystocele formation include 2 vaginal failure sites (apical support and paravaginal defects), 2 vaginal wall factors (vaginal width and length), and 2 levator ani factors (hiatus size and levator ani defects).
