Objective: To evaluate the accuracy of mean fetal kidney length measurement in determining the gestational age in third trimester
Design: Prospective study
Methodology: normal pregnant women in their third trimester with no maternal or fetal complications were selected and mean fetal kidney length and other biometric parameters were measured and gestational age was calculated for each and compared with LMP derived gestational age.
Result: Mean fetal kidney length was close to LMP derived gestational age when compared to other parameters with a significant p value (<0.0001).
Conclusion: mean fetal kidney length can be used as single parameter in 3rd trimester for estimation of gestational age.
