目标。本研究的目的是探讨成年志愿者肾脏的正常超声测量方法。对665名30、40、50、60和70岁的志愿者按年龄和性别分层随机抽样，测量了肾脏及其中央回声区的长度、宽度和厚度以及上极部的实质厚度。在志愿者俯卧的情况下进行了测量。计算肾脏体积、中央回声区和肾实质体积。肾脏大小、肾脏体积和实质体积与年龄、身高、体重、体重指数和全身面积相关。94名受试者也用仰卧位测量了肾脏长度。结果：肾脏长度的中位数左侧11.2厘米，右侧10.9厘米。左肾中位数为146 cm3，右肾中位数为134 cm3。肾大小随年龄增长而减小，几乎完全是由于肾实质减少所致。肾体积与总体面积相关性最好。肾脏长度与身高的相关性最好。受试者用仰卧位测量的肾脏长度与用仰卧位测量的肾脏长度没有显著差异。结论：对肾脏大小测量最准确的是肾体积，它与身高、体重和总体面积的相关性最强。临床上，肾脏长度的测量是最实用的，可以在受试者俯卧或仰卧的情况下进行。
OBJECTIVE. The purpose of this study was to investigate the normal sonographic measurements of the kidney in adult volunteers.SUBJECTS AND METHODS. Length, width, and thickness of the kidney and its central echogenic area and the parenchymal thickness of the upper pole were measured in an age- and sex-stratified random sample of 665 volunteers 30, 40, 50, 60, and 70 years old. Measurements were made with the volunteers prone. Volumes of the kidney, the central echogenic area, and the renal parenchyma were calculated. Renal dimensions and renal and parenchymal volume were correlated with age, height, weight, body mass index, and total body area. In 94 subjects, renal length was measured with the volunteers supine also.RESULTS. Median renal lengths were 11.2 cm on the left side and 10.9 cm on the right side. Median renal volumes were 146 cm3 in the left kidney and 134 cm3 in the right kidney. Renal size decreased with age, almost entirely because of parenchymal reduction. Renal volume correlated best with total body area. Renal length correlated best with body height. Measurements of renal length obtained with the subjects supine were not significantly different from those obtained with the subjects prone.CONCLUSION. The most exact measurement of renal size is renal volume, which showed the strongest correlation with height, weight, and total body area. Clinically, measurement of renal length is most practical and can be done with the subject prone or supine.
