Fetal kidney length as a useful adjunct parameter for determination of gestational age

Abstract

Introduction: Accurate gestational age assessment is important in obstetric care ultrasonography. Fetal kidney length is one of the emerging parameter in estimation of fetal gestational age in 3rd trimester. Objectives: Is to the ascertain the precision of ultrasonographic fetal kidney length measurement as a reliable parameter for determination of gestational age in 3rd trimester. Materials and Methods: Cross-sectional observational study was conducted on 152 antenatal women in the 3rd trimester. Gestational age was estimated by early fetal ultrasound measure and last menstrual period. Results: Mean kidney length showed a Pearson’s correlation coefficient of 0.907 and a determination coefficient of 0.822 with GA. The test was significant at P < 0.05. Conclusions: This study confirms that the fetal kidney length measurement for estimating the gestational age accurately in the 3rd trimester.
