Pelvic exenteration is radical surgical treatment that removes the urinary bladder, urethra, vagina, cervix, uterus, fallopian tubes, ovaries, rectum, anus, and in some cases, the vulva. The procedure leaves the patient with a permanent colostomy, where the colonic contents drain into a bag that attaches on the left side of the abdomen. The bladder is reconstructed from bowel to provide a reservoir which empties into a pouch on the abdomen.
