研究尿石成核、生长和积聚的体外实验方法较多，但直接观察尿石在体内环境下生长尚缺乏满意的方法。为此，我们设计了一种模拟人体内尿石生长的模型，研究了一组草酸钙尿石的生长变化。1资料与方法1.1尿液的收集：随机选择10例病人，男8例，女2例，平均年龄38岁。所有病人都患
There are many in vitro experimental methods for studying the nucleation, growth and accumulation of uroliths. However, there is a lack of satisfactory method to directly observe the growth of uroliths in vivo. To this end, we have devised a model that simulates urinary stone growth in humans and investigated the growth of a group of calcium oxalate uroliths. 1 Materials and Methods 1.1 Collection of urine: randomly selected 10 patients, 8 males and 2 females, mean age 38 years old. All patients are affected
