Xue et al reported equations for estimating renal depth from the dorsal skin surface in Chinese adults. The authors are from Xi'an Jiaotong University in Xi'An, China.
Patient selection: Chinese adult, from 22 to 65 years of age
Renal depth is the average of the distances to the anterior and posterior surface of the kidney at the hilum.
Parameters:
(1) weight in kilograms
(2) height in centimeters
(3) sex
depth of the left kidney for a male in cm =
= (0.083 * (weight)) - (0.058 * (height)) + 11.541
depth of the left kidney for a female in cm =
= (0.083 * (weight)) - (0.058 * (height)) + 10.89
depth of the right kidney for a male in cm =
= (13.498 * (weight) / (height)) + 2.141
depth of the right kidney for a female in cm =
= (13.498 * (weight) / (height)) + 1.816
