Cystocele (SIS-toe-seel) is when the bladder drops from its usual position and presses on the vaginal wall. A type of pelvic organ prolapse, cystocele or anterior vaginal prolapse, can occur if the pelvic floor muscles are weak, the organ is not in the correct spot in the pelvis in general (especially post child birth) or if there is too much pressure put on the pelvic floor. Common causes of a prolapsed bladder include repetitive stress over time (e.g., coughing, improper lifting) or during vaginal childbirth.
