A kidney length (pole to pole) in the coronal plane, sagittal and lateral diameter in the axial plane, and a kidney volume.

	Side	Male	p, R vs. L	Female	p, R vs. L	p, M vs. F
Kidney lenght, cm	Right	10.48 ± 1.29	0.452	10.50 ± 1.65	0.321	0.921
	Left	10.89 ± 1.56		10.56 ± 1.29		0.845
Sagittal diameter, cm	Right	5.52 ± 0.68	< 0.001	5.51 ± 0.55	< 0.001	0.973
	Left	5.15 ± 0.52		5.03 ± 0.53		0.174
Lateral diameter, cm	Right	5.24 ± 0.67	< 0.001	4.77 ± 0.61	0.002	< 0.001
	Left	5.59 ± 0.67		4.92 ± 0.55		< 0.001
Kidney volume, cm3	Right	174.96 ± 25.96	0.268	151.19 (137.70, 169.88)	0.175	< 0.001

Median (25th, 75 percentile) for skewed data; Mean with standard deviation (± SD) for normally distributed data. The left (L) and the right (R) kidney is compared by using paired Student's t test (normally distributed data) and Wilcoxon rank-sum test (skewed data); Male (M) and female (F) groups are compared by using Mann-Whitney U test. The level of significance was set as p < 0.05.
