Study of fetal kidney size by ultrasonography at different gestational age

Abstract

Normal fetal kidney dimensions are necessary to diagnose fetal kidney abnormalities. The maximum fetal renal growth occurs during 26-34 weeks gestation. Fetal kidney length correlates well with gestational age. Aim of the present study is to measure fetal kidney size at 30 and 38 weeks of gestation in singleton pregnancy. No statistically significant difference was found in the mean parameters of right and left kidney at a particular gestational age (p≥0.05) in this study. The mean length in mm of fetal kidneys was slightly longer than the approximate gestational age in weeks.
