Li and Wang reported equations for estimating renal depth from the dorsal skin surface. The authors are from China Medical University in Shenyang.
Parameters:
(1) age in years
(2) height meters
(3) weight in kilograms
(4) abdominal circumference in cm
depth of the left kidney in cm =
= (0.013 * (age)) - (2.71 * (height)) + (0.062 * (weight)) + (0.032 * (abdominal circumference)) + 4.037
depth of the right kidney in cm =
= (-2.449 * (height)) + (0.057 * (weight)) + (0.026 * (abdominal circumference)) + 5.41
