In renal stones very little is known about the relationships between size-shape parameters of the particles and packing arrangement. Factors such as the distance travelled by the deposited crystal, the residence time and fluid flow are believed to be important in modifying the distribution of size and the morphological characteristics of the mineral phase. This paper reviews some experimental studies on the growth of calcium oxalate crystals under different growth conditions. The crystals grown in aqueous media, gel systems, rat-kidneys, and in renal stones were studied by scanning electron microscope (SEM). Size distribution parameters, shape factors and distribution of shape were determined in stones using the SEM and image analysis system. Particle size and particle morphology analysis may provide unique information in the study of stone genesis, difficult to obtain by other methods.
关于肾结石中颗粒的尺寸-形状参数与堆积排列之间的关系，人们了解甚少。诸如沉积晶体移动的距离、停留时间和流体流动等因素，被认为在改变矿物相的尺寸分布和形态特征方面起着重要作用。本文综述了一些关于在不同生长条件下草酸钙晶体生长的实验研究。通过扫描电子显微镜（SEM）对在水性介质、凝胶系统、大鼠肾脏以及肾结石中生长的晶体进行了研究。使用SEM和图像分析系统测定了结石中的尺寸分布参数、形状因子和形状分布。颗粒尺寸和颗粒形态分析可能会在结石成因研究中提供独特的信息，而这些信息很难通过其他方法获得。
