Pelvic exenteration (or pelvic evisceration) is a radical surgical treatment that removes all organs from a person's pelvic cavity. The urinary bladder, urethra, rectum, and anus are removed. The procedure leaves the person with a permanent colostomy and vesicostomy. In women, the vagina, cervix, uterus, fallopian tubes, ovaries, and in some cases the vulva are removed. In men, the prostate is removed.
