[Renal echographic volumetry in the child. Normal patterns]

After experimental verification of an excellent correlation between volume measurements by water displacement and echography we have checked that there were no differences among several renal measurements performed in children by the same person. In our normal population of 313 children we assumed that the best correlation between somatometric and renal measurements parameter was between weight and renal volume. We have developed volumetric growth charts for both kidneys. There were no significant difference between right and left kidney.
