Rectocele
A rectocele ( /ˈrɛktəsiːl/ REK-tə-seel) results from a tear in the rectovaginal septum (which is normally a tough, fibrous, sheet-like divider between the rectum and vagina). Rectal tissue bulges through this tear and into the vagina as a hernia. There are two main causes of this tear: childbirth, and hysterectomy.
