渝东南地区尿路结石成分及特点分析

目的：探讨渝东南地区尿路结石成分构成情况，指导尿路结石的治疗和预防。方法采用化学显色法回顾性分析2008~2014年在该院就诊的渝东南地区1628例尿路结石患者的结石标本，并结合临床资料进行分析。结果尿路结石患者高发年龄为30~70岁，男性发病率高，上尿路结石发病率高。单一成分结石和混合性结石比例相似，尿路结石成分差异无统计学意义(P >0.05)。结石成分草酸钙检出率为82.9%，感染性结石为19.2%，但仅出现于肾结石和膀胱结石中，且呈现逐年上升趋势。黔江与彭水地区尿路结石以草酸钙成分为主，酉阳及秀山地区尿路结石中含感染性结石比例较高。结论尿路结石的化学成分分析简单、快捷、准确。结石成分分析对于了解结石成因，指导治疗和预防结石具有重要意义。
