Volumes and surface areas of 45 kidneys were determined ultrasonographically in vivo before autopsy and in a water bath phantom after autopsy by means of both the ellipsoid and the stepped section methods. Comparison of results revealed that renal volume may be determined by the simplest method, the ellipsoid method, with sufficient accuracy for clinical use. Results also revealed that renal mass expressed in grams may be directly obtained from renal volume expressed in milliliters, but mass in grams was found to correlate better with renal surface area than with renal volume. A formula relating renal mass to both volume and surface area was developed from regression analysis of the data and was found to provide a more precise estimate of renal mass than does mass computed from either volume or surface area alone.
在尸检前通过超声在体内测定了45个肾脏的体积和表面积，并在尸检后于水浴模型中采用椭球体法和阶梯状切片法进行了测定。结果比较显示，肾脏体积可用最简单的方法即椭球体法来测定，其准确性足以满足临床应用。结果还显示，以克表示的肾脏质量可直接从以毫升表示的肾脏体积获得，但发现以克表示的质量与肾脏表面积的相关性优于与肾脏体积的相关性。通过对数据进行回归分析，得出了一个将肾脏质量与体积和表面积相关联的公式，发现该公式比仅根据体积或表面积计算出的质量能更精确地估计肾脏质量。
