Vagino-uterine prolapse is a form of hernia through the vaginal outlet which may involve respectively the bladder and anterior vaginal wall, the anterior vaginal wall or the bladder and the cervix uteri; or the eversion may comprise cervix, or uterus, and the entire vaginal structure. The protrusion of the anterior pelvic segment is frequently a sliding of the bladder, pushing it before the anterior vaginal wall and dragging on the cervix where the uterus is firmly fixed as by firm ligaments and resistant peritoneum. The traction on the cervix causes a hypertrophic elongation of the supravaginal portion of the cervix. The anterior and posterior vaginal walls are attached to the cervix at different levels so that such an elongation may occur in the vesical portion of the cervix with complete eversion of the anterior vaginal wall and the cervix, while the posterior vaginal, remains intact and presents its normal length.
