Transabdominal Versus Transvaginal Ultrasound to Assess the Thickness of the Lower Uterine Segment.

aims to determine the accuracy of measurement of the LUS thickness by trans-abdominal and transvaginal ultrasound at term pregnancy in comparison to the actual thickness of LUS measured with manual caliper measurement during cesarean delivery.

Study hypothesis: In women with previous cesarean delivery, determination of the LUS thickness can be done by trans-abdominal and transvaginal ultrasound at term pregnancy and compared to the actual thickness of LUS measured with a manual caliper at cesarean delivery.

Study question: considering transabdominal & transvaginal ultrasound, which of them would be more accurate in the assessment of LUS thickness?
