Sonographic assessment of renal volume in Indian children.

In an attempt to making norms of renal volume (RV) in Indian children, 240 children (137 boys and 103 girls) below 5 years of age were subjected to sonographic examination in supine position. Left RV in female children increased from 18.04 mm3 in early infancy to 48.36 mm3 in 4-5 year age group. Similar increase was observed in the right RV. There was no significant left vs. right difference in RV in boys and girls (p > 0.05). Similarly, the RV did not differ significantly in both sexes (p > 0.05, in all age groups except 4-5 years, p = 0.04).
