what is prolapse of vaginal vault
A RealAge answered. Vaginal vault prolapse is a condition in which the upper part of the vagina drops down into the vaginal canal. Vaginal vault prolapse can be a complication of a hysterectomy (surgical removal of the uterus) because the uterus helps to hold up and support the vagina. It is also more likely to occur in women who have given birth vaginally, who are obese or who have had other pelvic organ prolapses.
