Abstract:

【Abstract】 Objective To provide theoretical basis of clinical personalized treatment and prev-ention recurrence for patients with urinary stones,.using infrared spectrum method to analyze the urinary stones composition in Nanhai District,.Guangdong Province.Method The urinary stones in 986 cases were excluded naturally or performed extracorporeal shock-wave lithotripsy,.which were analyzed by the infrared spectrum method.Results Urinary stones were more often found in male patients than that in female,.and the ratio was 1.34∶1 The incidence of urinary tract stones between 51-60 years old were higher than any other age stage. The upper urinary tract stones were more frequently found than the lower urinary tract stones,and the ratio was 9.49∶1. Six types of chemical components were detected in calculi.There were calcium oxalate monohydrate, calcium oxalate dihydrate, carbonated apatite, anhydrous uric acid, hexahydrate phosphate magnesium ammonium and cystine. Mixed components stones were found in 647 cases,.accounting for 65.6%. And calcium stones were found in 853 cases,.accounting for 86.51%. The detection rate of calcium oxalate was highest in all the chemical components,accounting for 77.38%,.followed carbonated apatite (5.27%) and uric acid composition (15.8%). Conclusion It is significant to analyze the urinary stone composition for investigating the cause of stones,.and preventing stone formation and recurrence.

摘要：

【摘要】 目的 应用红外光谱法分析广东南海地区泌尿系结石患者的结石,为临床个性化防治泌尿系结石及复发提供理论依据。方法 通过自然排出、碎石后排出或手术取出获得结石样本986例,并应用红外光谱法对其行结石成分分析。结果 泌尿系结石患者男女比例为1.34∶1,51岁~60岁年龄阶段患者所占比例最高,上尿路结石发病人数明显多于下尿路结石,比例达9.49∶1。定性分析共检测出一水草酸钙、二水草酸钙、碳酸磷灰石、无水尿酸、六水磷酸镁铵和胱氨酸6种化学成分。混合成分结石647例,占总人数的65.6%;含钙结石853例,占86.51%。草酸钙检出率最高,占77.38%,其次是碳酸磷灰石(5.27%)和尿酸(13.29%)成分。结论 采用红外光谱法分析泌尿系结石成分,对于了解结石成因、预防结石形成和复发具有重要的意义。
