In 52 healthy premature infants, 104 kidneys were sonographically examined and kidney length was measured. Kidney length was compared with four parameters: body weight, body length, body surface area, and gestational age. Scatter plots of these data demonstrated that kidney length versus body weight conformed well to a linear distribution with a high correlation coefficient. A nomogram for kidney length versus body weight in premature infants is also presented.
对52名健康早产儿的104个肾脏进行了超声检查并测量了肾脏长度。将肾脏长度与四个参数进行比较：体重、身长、体表面积和胎龄。这些数据的散点图表明，肾脏长度与体重的关系符合线性分布，相关系数较高。还给出了早产儿肾脏长度与体重的列线图。
