The left kidney is normally higher than the right kidney. Their axis parallels the psoas margins. In children greater than 18 months old the kidney length is equal to the length of the first four lumbar vertebra, while in younger children the kidney size may be 5 or 6 vertebral bodies in length.

Normal variants include fetal lobulations, and aberrant papillae.
