Dilatation of the uterus is also called dilatation of the cervix, which may have the following clinical causes: 1. Tumors of the cervix cause dilatation of the cervix, which may clinically manifest as increased vaginal discharge, increased menstrual blood, and may be accompanied by symptoms of abdominal distension and frequent urination. 2. The dilatation of the cervix at the end of pregnancy is a normal physiological reaction, and it is through the dilatation of the cervix that the uterus contracts in order to expel the fetus normally and end the delivery. Therefore, the clinical treatment for cervical dilation varies depending on the cause. If the dilatation is caused by a gynecological disease, the treatment should be tailored to the cause.
