Table 2 Absolute and relative renal dimensions. The relative measurements were calculated according to the body weight, the body height and the body surface. A) Comparison of absolute and relative renal values according to kidney laterality. B) Comparison of absolute and relative renal data according to sex

From: Reference values and sex differences in absolute and relative kidney size. A Swiss autopsy study
