摘　　要：目的分析在输尿管中下段结石诊断中应用CT尿路造影的临床价值。方法纳入2021年3月—2023年3月南京医科大学无锡人民医院接受诊治的106例疑似输尿管中下段结石的患者作为研究对象,均给予常规CT和CT尿路造影检查,以手术检查结果为诊断金标准,对常规CT和CT尿路造影的诊断效能,并对比常规CT和CT尿路造影检查诊断输尿管中下段结石的数量、大小和结石部位的符合率。结果CT尿路造影检查的准确率95.28%、灵敏度97.53%、特异度88.00%、阴性预测值91.67%均高于常规CT,差异有统计学意义(χ^(2)=12.266、8.890、3.947、8.619,P<0.05);CT尿路造影检查的阳性预测值高于常规CT,差异无统计学意义(P>0.05);CT尿路造影诊断输尿管中下段结石数量的符合率高于常规CT,差异有统计学意义(P<0.05)。结论CT尿路造影在输尿管中下段结石诊断中的效能良好,可帮助临床明确结石数量、大小和部位,尤其是在微小结石检出方面的符合率较高,可提高诊断的精准性。Objective To analyze the clinical value of CT urography in the diagnosis of middle and lower ureteral stones.Methods 106 patients with suspected middle and lower ureteral stones who were diagnosed and treated at Wuxi People's Hospital of Nanjing Medical University from March 2021 to March 2023 were included as research subjects,and all of them were given routine CT and CT urography examinations.With the results of surgical examination as the diagnostic gold standard,the diagnostic efficacy of conventional CT and CT urography,and the consistency rate of conventional CT and CT urography in diagnosing the number,size and location of stones in the middle and lower ureters was compared.Results The accuracy of CT urography was 95.28%,sensitivity 97.53%,specificity 88.00%and negative predictive value 91.67%higher than conventional CT,and the differences were statistically significant(χ^(2)=12.266,8.890,3.947,8.619,P<0.05).The positive predictive value of CT urography was higher than that of conventional CT,and the difference was not statistically significant(P>0.05).The consistency rate of CT urography in diagnosing the number of stones in the middle and lower ureters was higher than that of conventional CT,and the difference was statistically significant(P<0.05).Conclusion CT urography has good performance in diagnosing stones in the middle and lower ureters,and can help clinically determine the number,size and location of stones.It has a high coincidence rate especially in the detection of small stones,which can improve the accuracy of diagnosis.
