The renal lengths of 200 adults with normal renal and cardiac status were measured sonographically in the supine position to establish normative values of renal length for the locality and to correlate them with some anthropometric parameters. The ranges of normal kidney length obtained were 8.3 -12.8 cm and 8.0- 12.5 cm for the left and right kidneys respectively. The mean renal lengths of males were slightly higher than those of females. Renal length correlated positively with subject weight and not with the height or age of patients. This study was able to establish a normogram of renal length for the locality, with mean renal length of 10.6 cm and 10.3 cm for the left and right kidneys respectively. The renal lengths obtained showed no racial dependence. The positive correlation with body weight seems to substantiate the longer lengths of male kidneys versus female kidneys. The study also established a confidence interval of difference between right and left kidneys for the different age groups that could prove invaluable in making critical decisions on size differences in unilateral renal disease.
对200名肾脏和心脏状况正常的成年人在仰卧位进行超声测量肾脏长度，以确定该地区肾脏长度的正常值，并将其与一些人体测量参数相关联。获得的正常肾脏长度范围，左肾为8.3 - 12.8厘米，右肾为8.0 - 12.5厘米。男性的平均肾脏长度略高于女性。肾脏长度与受试者体重呈正相关，与患者的身高或年龄无关。本研究能够建立该地区肾脏长度的标准图，左肾平均长度为10.6厘米，右肾平均长度为10.3厘米。所获得的肾脏长度无种族差异。与体重的正相关似乎证实了男性肾脏比女性肾脏更长。该研究还为不同年龄组建立了左右肾之间差异的置信区间，这在对单侧肾脏疾病的大小差异做出关键决策时可能具有重要价值。
