1.7.1\ Method

The patient should have a full urinary bladder. Probe lengthwise is placed in the abdominal wall of the hypogastrium, the direction of sound beam through the middle longitudinal section of the uterus.

1.7.2\ Section Structure

The anechoic area inferior to the abdominal wall is the engorged bladder, and behind the bladder is the uterus. The left part which is toward post ridge is the uterus base, and the right part is the cervix. The hyperechogenicity line which is located at the uterus center is the uterus cavity line.

1.7.3\ Measuring Method and Normal

Measuring length diameter and anteroposterior diameter of the uterus from this section, the measurement of length diameter from the surface of the uterus base to the endostoma of the cervix, the normal value is 5–7 cm; the measurement of anteroposterior is the maximum AP distance which is vertical of upper-down diameter, the normal value of which is 3–4 cm.

1.7.4\ The Clinical Application Value

The longitudinal section is the most important section to judge the position of the uterus and understand whether the size and shape of the uterus is normal.
