In gynecology, a rectocele (/ˈrɛktəsiːl/ REK-tə-seel) or posterior vaginal wall prolapse results when the rectum bulges (herniates) into the vagina. Two common causes of this defect are childbirth and hysterectomy. Rectocele also tends to occur with other forms of pelvic organ prolapse, such as enterocele, sigmoidocele and cystocele. Although the term applies most often to this condition in females, males can also develop it. Rectoceles in men are uncommon, and associated with prostatectomy.
