摘　　要：目的:分析各种输尿管微小结石的CT表现,探讨CT平扫及各种后处理技术在输尿管微小结石中的诊断价值。方法:收集无锡市第四人民医院输尿管结石患者20例,均行64层螺旋CT平扫检查,并进行薄层后处理重建(包括曲面重建),3例进行了静脉肾盂造影(IVP)检查,5例进行了腹部平片(KUB)检查。结果:右侧输尿管结石12例,左侧输尿管结石6例,两侧输尿管均有结石2例;输尿管下段结石5例,中段结石8例,上段结石7例;结石直径均小于10mm,结石大小为2mm^9mm,平均直径5±1.6mm;3例IVP检查中,造影剂在输尿管结石处受阻,表现为充盈缺损影,结石上方输尿管及肾盂扩张积水;5例KUB检查中,输尿管结石表现为输尿管路径上的斑点状高密度影。结论:多层螺旋CT平扫较腹部平片对输尿管微小结石有更高的检出率,尤其是CT薄层重建技术更佳,值得普及推广应用。Objective： To analyze CT manifestations of various small ureter stones to explore CT scan and all kinds of post-processing technique in the diagnosis of ureteral small stones. Methods： 20 cases of ureteral calculi patients collected in wuxi city,the fourth people’s hospital,with 64 layer spiral CT scan,and thin layer post-processing reconstruction（ including surface reconstruction）,3 cases of IVP examination,5 cases of KUB examination. Results： 12 cases of ureteral calculi were on the right side,6 cases of ureteral calculi were on the left side,2 cases were on both sides of the ureter; 5 cases of ureteral calculi were in the lower ureter,8 cases were in the middle ureter,7 cases were in the upper ureter; The diameter of all cases were less than 10 mm,stones size of 2 mm to 9 mm,the average diameter of 5 ± 1. 6 mm; 3 cases of IVP examination,the contrast agent in ureteral calculi,show the filling defect,upper ureteral and pyelectasis water; 5 cases KUB examination,ureteral calculi of ureteral path punctate high density shadow. Conclusions： Multislice CT scan has a higher detection rate to the tiny ureter stone than abdominal plain film,especially thin layer CT reconstruction technology is better,worthy of popularization application.
