摘　　要：目的探讨双源CT双能量成像联合曲面重建(CPR)技术在输尿管结石诊断中的应用。方法收集2017年1月至2020年12月本院收治的手术、输尿管镜检查和体外碎石确诊的输尿管结石患者82例,所有患者治疗前均使用双源CT双能量成像联合曲面重组进行诊断,分析其CT表现,记录输尿管结石检出率和位置,与临床结果进行比对,并区分结石成分。结果82例输尿管结石患者中,双源CT双能量成像联合曲面重建技术诊断78例,诊断准确率为95.12%,其中输尿管上段33例,输尿管中段17例,输尿管下段28例,尿酸盐结石21例,非尿酸盐结石57例。结论双源CT双能量成像联合曲面重组技术对输尿管结石具有重要的诊断价值,并能区分结石成分,是临床诊断输尿管结石的首选。Objective To investigate the application of dual-source CT dual-energy imaging combined with curved planar reformation(CPR)in the diagnosis of ureteral Calculi.Methods A total of 82 patients with ureteral Calculi diagnosed by operation,ureteroscopy and extracorporeal lithotripsy were collected from January 2019 to December 2020.All patients were diagnosed by dual-source CT dual-energy imaging combined with curved planar reformation before treatment,the CT findings were analyzed,the detection rate and location of ureteral Calculi were recorded,compared with the clinical results,and the composition of Calculi was distinguished.Results Among 82 cases of ureteral Calculi,78 cases were diagnosed by dual-source CT dual-energy imaging combined with curved surface reconstruction,the diagnostic accuracy was 95.12%,including 33 cases of upper ureter,17 cases of Middle Ureter,28 cases of lower ureter and 21 cases of Urate Calculi,non-urate Calculus in 57 cases.Conclusion Dualsource CT dual-energy imaging combined with curved planar reformation is of great value in the diagnosis of ureteral Calculi,and is the first choice in the clinical diagnosis of ureteral Calculi.
