Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship:
Total hysterectomyâThe entire uterus, including the cervix, is removed. Supracervical (also called subtotal or partial) hysterectomyâThe upper part of the uterus is removed, but the cervix is left in place. This type of hysterectomy can only be performed laparoscopically or abdominally.
Types of hysterectomy include total hysterectomy, in which the uterus and cervix are removed, and radical hysterectomy, in which ovaries, oviducts, lymph nodes, and lymph channels are removed with the uterus and cervix. Menstruation ceases after either type is performed. A vaginal irrigation may be given preoperatively.
