Uterine prolapse

Prolapse of the Uterus. Prolapse of the uterus results from weakness of the supporting structures of the pelvic floor, and is often associated with a cystocele and rectocele. In progressive stages, the uterus becomes retroverted and descends down the vaginal canal to the outside. In first-degree prolapse, the cervix is still well within the vagina. In second-degree prolapse, it is at the introitus. In third-degree prolapse (procidentia), the cervix and vagina are outside the introitus.
