Necrosis of the uterus usually refers to the local tissue shedding and necrosis of the cervix after physical therapy or local treatment with corrosive drugs. This is because after the cervical treatment, the local tissue of the cervix will be necrotic, and this necrotic tissue will be shed about a week after the operation, which is a benign development process and a good phenomenon. During the peeling process, it is best to keep the vulva clean, as it is often accompanied by a small amount of vaginal bleeding, and it is recommended to wash the vulva with water twice a day to avoid pathogenic infections, and to refrain from sexual intercourse for two months after treatment.
