红外光谱法定性分析尿路结石成分326例

Qualitative analysis of lithangiuria through infrared spectroscopy:a report of 326 cases

目的对尿路结石进行定性分析,为治疗和预防提供依据。方法使用红外光谱分析仪对结石进行化学成分分析,研究不同成分结石的分布情况。结果尿路结石男女比例2.2∶1,上、下尿路结石比为9.5∶1;结石成分以混合性居多,其中又以草酸钙、磷酸钙与尿酸的混合结石为主;感染性结石多见于女性患者,尿酸结石则多见于中老年男性患者。结论红外光谱法定性分析尿路结石,可充分了解结石性质,具有临床治疗和科学预防价值。

Objective To analyze qualitatively lithangiuria so as to provide the evidence for improving the treatment and prevention of lithangiuria.Methods The chemical composition was determined by an infrared spectroscopic analyzer and the data were analyzed to determine the distribution of different stone compositions.Results In lithangiuria,the ratio between the male and female was 2.2∶1,and that between the upper urinary tract and lower urinary tract was 9.5∶1.The composition analysis revealed that the majority of lithangiuria was mixed calculus.Calcium oxalate,calcium phosphate and trioxypurine formed the main compositions of stones.Infection-caused stones were more common in the female,but uric acid stones were more common in the aged male.Conclusions The qualitative analysis of lithangiuria through infrared spectroscopy contributes greatly to identify the stone composition,which is significant in prevention and therapy.
