RECTOCELE - An abnormal protrusion of the wall of the rectum into the bladder. This condition can result in stress incontinence and difficulty in passing stool from the rectum.
When the rectum bulges into or out of the vagina, it is called a rectocele. It is caused by a weakness of the back wall of the vagina. A large rectocele may make it very hard to have a bowel movement, especially if you have constipation. Some women have to push the bulge back into the vagina in order to complete a bowel movement.
