The midline defect is a cystocele caused by the overstretching of the vaginal wall; the paravaginal defect is the separation of the vaginal connective tissue at the arcus tendineus fascia pelvis; the transverse defect is when the pubocervical fascia becomes detached from the top (apex) of the vagina.
