The chemical composition of the urinary stones of 32 cases was examined by quantitative chemical analysis and material mechanics principle was used to measure the density, the rigidity and the compressive strength of the urinary stones taken from 32 patients, lithotriptic test was performed in 13 cases. 对32例的尿结石采用化学定量分析法进行化学成分分析,利用材料力学原理和方法测定密度、硬度和抗压强度,并对其中13例的尿结石作体外碎石试验。
Results The lithotriptic rate of the 2620 cases was 99.39%, the failure rate was 0.61% and the incidence of stone street was 0.88%. 结果2620例的碎石率达99.39%,无效率0.61%,石街发生率0.88%。
