Growth of the fetal kidney. Ultrasonographic measurement of the ratio of average kidney diameter to biparietal diameter.
Kidney size was studied ultrasonographically in 101 normal fetuses. A ratio of average kidney diameter to biparietal diameter was established and found to be constant across gestation. Three fetuses with known urinary tract pathology were then studied and were found to have ratios significantly different from normal ones.
