| 摘 要： | 目的分析近年来珠江三角洲地区泌尿系结石患者的结石组分和尿微晶性质,期望为尿石症的预防和治疗提供启示。方法采用X射线衍射(XRD)和傅立叶变换红外光谱(FT-IR)对随机抽样的30例结石样本进行联合分析;同时采用纳米粒度仪研究尿石症患者尿液中纳米微晶的平均粒径、粒度分布、多分散系数(PDI)和Zeta电位等性质,并与健康对照者进行比较。结果珠江三角洲地区泌尿系结石以草酸钙结石为主,占76.6%;其次为尿酸结石,占16.7%;磷酸钙结石约占6.7%。尿石症患者尿微晶的平均粒径、粒度分布、多分散系数(PDI)和Zeta电位与健康对照者比较差异有统计学意义。结论草酸钙、尿酸和磷酸钙构成了珠江三角洲地区泌尿系结石的主要成分;尿石症患者和健康对照者尿微晶在平均粒径、粒度分布、多分散系数(PDI)和Zeta电位等方面性质的差异使得正常人不容易得结石。
