Abstract
Background: Accurate monitoring of fetal gestational age is one of the most critical components of prenatal care. The ability to accurately determine the fetal gestational age and growth was recognizing its abnormal patterns, helps us to decide that if early intervention is necessary in high risk pregnancy or not.
Aims: This study intends to determine the accuracy of fetal gestational age estimation using mean fetal kidney length and comparing its efficacy with other biometric parameters and gestational age derived from last menstrual period as taken as a standard.
Material & Method: This cross section hospital based study period of one year from 2015 to 2016. Pregnant women (n=100) with known dates of different parity and ages were included in this study. The subjects were taken informed before they were enrolled in the study.
Results: In present study, gestational age was ranging from 28 to 40 weeks and their mean BPD was ranging from 68.00 to 98.00 mm (table 2) and their mean femur length was ranging from 53.00 to 78.00mm.
Conclusion: The kidney length is more accurate method of determining gestational age than the fetal biometric indices of biparietal diameter, head circumference, femur length and abdominal circumference between 24 to 38 weeks of gestation. However, large and multicentric studies are required to recommend it.
Keywords: Biparietal Diameter (BPD), Head Circumference (HC), Femur Length (FL) and Abdominal Circumference (AC).
