Figure 1

Representative ultrasound images of the kidney. A. Showing absolute renal length (RL) measurement. The white dotted line indicates the absolute RL. B. Showing cortical and parenchymal thickness measurements. The white dotted arrow indicates the renal parenchymal thickness; white solid arrow indicates renal cortical thickness.
