Estimation of gestational age in third trimester using mean fetal kidney length in comparison with fetal biometry

Background: Accurate estimation of gestational age (GA) is crucial for providing quality health care and need intervention in inadvertent conditions such as fetal growth restriction. Various parameters are used measuring GA, but none them valid 3rd trimester. Recently some studies focused on Fetal kidney length (FKL) measurement correct GA. This study the validation accuracy FKL.Objective: Estimation third trimester using mean foetal length. Comparing FKL with Biparietal diameter (BPD), Head circumference (HC), Abdominal (AC), Femur (FL).Methodology: Ultrasonography was done among 150 healthy antenatal known Last menstrual period (LMP) to measure FKL, BPD, HC, AC, FL.Results: In present study, 51.3% were primi paras. With increased also increased. Regarding correlation, had very strong correlation GA than other indices. Conclusion: better parameter estimating
