Ultrasound has been used as a convenient examination method to obtain an estimate of the kidney size and parenchymal thickness. The aim of this study was to determine the relationship between the renal parenchymal thickness and individual renal function. Renal ultrasonography to determine parenchymal thickness and 99mTc-DTPA renal scan to detect individual renal function were carried out on 30 patients. The statistic analysis showed poor correlation between these two factors. The correlation coefficients is 0.1 only. However, the correlation coefficients of the difference of bilateral renal parenchymal thickness and the difference of bilateral renal function in the same patient is much higher (r = 0.67). So, it is unreliable to predict the random single renal function based on parenchymal thickness only. However, in the same patient, it is sometimes worthwhile to differentiate bilateral renal function based on the difference of renal parenchymal thickness between the two kidneys.
超声已被用作一种便捷的检查方法来估算肾脏大小和实质厚度。本研究的目的是确定肾实质厚度与个体肾功能之间的关系。对30例患者进行了测定肾实质厚度的肾脏超声检查以及检测个体肾功能的99mTc - DTPA肾扫描。统计分析表明这两个因素之间的相关性较差。相关系数仅为0.1。然而，同一患者双侧肾实质厚度差异与双侧肾功能差异的相关系数要高得多（r = 0.67）。因此，仅基于实质厚度来预测随机单肾的功能是不可靠的。然而，对于同一患者，有时根据两肾之间肾实质厚度的差异来区分双侧肾功能是值得的。
