Hysterectomy can be performed without sanitary napkins because there is no menstrual flow in hysterectomy. Hysterectomy is the removal of the endometrium, so there is no cyclic stripping of the endometrium, and there is no menstrual flow, so there is no need to bring sanitary napkins clinically. Hysterectomy clinically can be divided into total hysterectomy and subtotal hysterectomy, if the total hysterectomy with cervix removed, there is no menstrual flow, if the uterus is high subtotal hysterectomy, may be with the change of ovarian function, the part of the cervix can be a small amount of endometrial exfoliation, a small amount of cyclic bleeding will occur.
