Abstract

Background: The knowledge of accurate estimation of gestational age (GA) for an obstetrician is first and foremost to date the pregnancy as early as possible during the antenatal period for proper management of all the pregnancies. Ultrasound parameters like BPD, HC, AC and FL in second and third trimesters are not very reliable for dating the pregnancy. Fetal kidney length (FKL) and transcerebellar diameter (TCD) have been studied and shown to strongly correlate with the gestational age. Materials and methods: A prospective observational study was conducted on 600 women with normal singleton pregnancies. Fetal kidney length and transcerebellar diameter were measured using Voluson E8 (Wipro GE) ultrasound machine. Statistical analysis was done using tests of correlation and simple linear regression. All analysis was done by using SSPS statistics 24.0. Results: The result indicates that the fetal kidney length and transcerebellar diameter in the present study correlated well with the assigned gestational age. A positive linear relationship of gestational age with fetal kidney length and transcerebellar diameter was found. Correlation of gestational age with fetal kidney length and transcerebellar diameter was 0.875 and 0.975 respectively. Conclusion: The present study reveals that fetal kidney length and transcerebellar diameter can be used as parameters in estimating gestational age, especially in later trimesters, where biometric indices may not be much reliable.
