Pelvic organ prolapse is a condition where any of the pelvic floor organs drop into or outside of the vaginal canal or anus. The most common causes of pelvic organ prolapse are pregnancy and childbirth. Other causes include constipation, hysterectomy, and chronic, long-term coughs.
A fallen bladder, also known as cystocele or prolapsed bladder, is common after hysterectomies. It involves the bladder falling into the vaginal canal.
