Anterior prolapse, also known as a cystocele (SIS-toe-seel), occurs when the supportive tissue between a woman's bladder and vaginal wall weakens and stretches, allowing the bladder to bulge into the vagina. Anterior prolapse is also called a prolapsed bladder.
Uterine prolapse occurs when the uterus sags or slips from its normal position and into the vagina (birth canal). Uterine prolapse may be incomplete or complete. An incomplete prolapse occurs when the uterus is only partly sagging into the vagina. A complete prolapse occurs when the uterus falls so far down that some tissue protrudes outside of the vagina.
Vaginal vault prolapse: This type of prolapse may occur following a hysterectomy (surgical removal of the uterus). Because the ligaments surrounding the uterus provides support for the top of the vagina, this condition is common after a hysterectomy. In vaginal vault prolapse, the top of the vagina gradually falls toward the vaginal opening.
