SONOGRAPHIC ASSESMENT OF GESTATIONAL AGE BY THE FETAL KIDNEY LENGTH AND VOLUME AFTER 18 WEEKS OF GESTATION IN LOCAL POPULATION IN NORTH- WESTERN AHMEDABAD.

Introduction: Ultrasonography is widely used indetermination of GA From 2nd trimester onwards apart from Routine parameters used for GA estimation like BPD, HC, and AC and FL, FKL is emerging as useful parameter in estimation of GA more reliably. to dene how precisely FKL measurement by USG can det Objective: ermine GA From 18 weeks onwards. to create baseline reference values of FKL in local population in north- western Ahmedabad from 18 weeks onwards to see population specic variations. A Cross-Sectional - observational Study was Material and Methods: conducted on 200 antenatal women in the second and third trimester with normal singleton pregnancies using SAMSUNG HS50 ultrasound machine. The result suggests a positive linear relationship of GA with fetal kidney Results: length. However, no correlation of GA with volume was noted. FKL measurement can be used as a reliable ultrasonographic Conclusion: parameter for estimating the GA in the 2nd and 3rd trimester and correlation increases when used with other parameters. Population specic baseline reference values for north- west ahmedabad of FKLs for the estimation of GA should be adopted rather than relying on the Caucasians values as universal patterns
