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.
Nearly all endocervical polyps can be removed through the vagina, as they are present at the opening of the cervix, but uterine/endometrial polyps are usually removed via the D&C with hysteroscopy method, which is slightly more invasive but definitely less traumatic than a hysterectomy.
