Pelvic organ prolapse is a condition in which the pelvic organs (such as the bladder, uterus, rectum, or intestines) drop from their normal position in the pelvic cavity and press against the walls of the vagina. There are four types of pelvic organ prolapse: anterior, posterior, apical, and cystocele. Anterior prolapse is when the bladder drops down and presses against the front wall of the vagina. Posterior prolapse happens when the rectum drops down and presses against the back wall of the vagina. Apical prolapse involves the uterus and cervix dropping down and pressing against the top of the vagina. Finally, cystocele involves the bladder dropping down and pushing against the front wall of the vagina. Treatment for pelvic organ prolapse will depend on the severity of the condition and the type of prolapse present. Physical therapy can help to strengthen the muscles of the pelvic floor and improve the symptoms of pelvic organ prolapse.
