Conditions

Lower Uterine Segment Thickness, Trans Abdominal Ultrasound, Transvaginal Ultrasound

Brief summary

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?

Interventions

DIAGNOSTIC_TESTtransabdominal ultrasound and transvaginal ultrasound

Within a week before scheduled delivery,antepartum transabdominal and transvaginal ultrasound will be performed with moderately full bladder.
