维吾尔族及汉族尿路结石的双能量CT特征及罹患结石危险因素分析

Dual-energy CT features of urinary calculi and risk factors comparison between Uyghur and Han

目的应用双源CT双能量扫描对比维吾尔族(维族)及汉族患者尿路结石的CT特征及罹患结石危险因素,探讨两民族尿路结石发病的差异性及主要诱因。方法双能量CT发现泌尿系结石患者381例,汉族291例,维族90例,对结石发生率、发生部位、双能量不同斜率下结石颜色、结石HU差值、比值、DEI值及双能量分析值以及吸烟、饮水量及家族患结石病史进行比较。结果汉族患者结石发生率高于维族患者(P<0.05),而结石好发部位汉族绝大多数位于肾脏,维族多位于输尿管,发生部位的比较存在统计学差异(P<0.05);双能量分析不同斜率下结石颜色无统计学差异(P>0.05);HU比值、差值及双能量分析值存在统计学差异(P<0.05),DEI值无统计学差异(P>0.05);吸烟、饮水量及家族患结石史3个危险因素无统计学差异(P>0.05)。结论汉族患者尿路结石发生率较维族高,双能量HU比值、差值及双能量分析值存在差异,可能与两民族患者结石成分不同有关。

Objective Application of dual-energy dual-source CT scan contrast Uyghur and Han patients CT characteristics and risk factors of urinary tract stones to explore the main causes of the incidence of urinary tract stones of these two nations. Methods 381 patients with urinary calculi were diagnosed by Dual-energy CT,including291 cases of Han,Uyghur 90 cases. The incidence,location of the urinary tract stones and the color,HU difference,DEI value of dual energy,dual energy values of urinary tract stone in different slopes were analysed. And smoking,the risk of water intake and family history of stones were compared between Uyghur and Han. Results The quantity of stones in Han Patients was higher than that in Uyghur patients（ P〈0 05）. The stones predilection sites in two races were different（ P〈0 05）. The stones predilection sites in Han located in kidneys,while uretersin Uyghurs; the color of the stones in different slope with dual energy analysis had no statistically significant difference（ P〈0 05）; HU difference,ratio,the value of dual energy analysis had significant differences（ P〈0 05）,while DEI value had no significant difference（ P〈0 05）. Conclusion The incidence of urinary calculi in Han patients higher than that of Uyghur. HU difference,ratio,dual-energy analysis value were significantly different between two races,which may be related to the stone composition.
