Comparison of Fetal Kidney Length with Biparietal Diameter (BPD) in Second Trimester and Femur Length (Fl) in Third Trimester for Prediction of Gestational Age

Abstract

To compare the accuracy in estimation of gestational age with  fetal  kidney  length  and  biparietal  diameter ( BPD ) in second trimester.To compare the accuracy in estimation of gestational age with fetal kidney length and femur length ( FL ) in third trimester. Obstetric sonography was performed in 200 pregnant women with uncomplicated pregnancy to evaluate  the efficacy of kidney length ( KL ) as  a  measure to  calculate  the predicted gestational age. Gestational age  ranges from  20 weeks to 38 weeks. Only patient with known LMP, previous history of normal menstrual cycle and without any exclusion criteria were included in the study. In the field of obstetrics to achieve a good perinatal outcome, gestational age assessment is vital, because both prematurity and post maturity of the foetus have many untoward effects on the foetus.
