Overview
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.
Straining the muscles that support your pelvic organs may lead to anterior prolapse. Such straining occurs during vaginal childbirth or with chronic constipation, violent coughing or heavy lifting. Anterior prolapse also tends to cause problems after menopause, when estrogen levels decrease.
For a mild or moderate anterior prolapse, nonsurgical treatment is often effective. In more severe cases, surgery may be necessary to keep the vagina and other pelvic organs in their proper positions.
