Abstract

This paper represents the results of experimental study on the microstructure of uric acid and calcium oxalate crystallites in renal stones. The size distribution parameters and morphological characteristics of the microcrystals forming the stone were determined using SEM and image analysing system. Information on the fabric of the renal stones examined indicates that the mean volume diameter is 15.5 microns for uric acid and 32 microns for calcium oxalate stones. The polydispersity index gamma, the shape factor phi, and the distribution of particle shape show close similarity. Quantitative studies on stone microstructure could furnish valuable information on stone genesis.

摘要

本文介绍了关于肾结石中尿酸和草酸钙微晶微观结构的实验研究结果。利用扫描电子显微镜（SEM）和图像分析系统测定了形成结石的微晶的尺寸分布参数和形态特征。所检测肾结石结构的信息表明，尿酸结石的平均体积直径为15.5微米，草酸钙结石为32微米。多分散指数γ、形状因子φ以及颗粒形状分布显示出密切的相似性。对结石微观结构的定量研究可为结石成因提供有价值的信息。
