Uterocervical Angle Versus Cervical Length as a Predictor of Labor Induction in Term Singleton Pregnancy

"With the patient in the lithotomy position and empty bladder, care was taken to avoid applying pressure to the cervix with the transvaginal probe. The cervix was aligned in the midline, and the endocervical canal was visualized throughout its length.During cervical measurement, care was taken to ensure that the internal os, external os, and entire endocervical canal were visible in the same image. With the endocervical canal, external os, and internal os linearly displayed on the screen, the angle between the endocervical canal, anterior and posterior uterine segment was measured using the ultrasound's angle measurement feature.For the measurement of the uterocervical angle, the first line of the angle was defined along the endocervical canal used for measuring cervical length, and the second line was drawn from the internal os along the anterior uterine segment for a minimum of two centimeters. The angle between these two lines was recorded as the uterocervical angle in the form."
