目的　探讨螺旋CT对输尿管结石的诊断价值。　方法　对 2 5例临床表现急性腰腹痛、镜下血尿 ,可疑输尿管结石 ,B超、KUB、IVU未显示结石的患者 ,行螺旋CT检查 ,将获得的容积图像三维立体重建成像处理。　结果　 2 4例螺旋CT图像显示出输尿管结石 ,确诊率 96 %。 3例CT三维立体成像显示结石引起肾盂、输尿管扩张及结石周围组织水肿等继发性变化。　结论　螺旋CT诊断输尿管结石安全、快捷、准确 Objective To investigate the diagnostic value of spiral CT in ureteral calculi. Methods Twenty-five patients with acute abdominal pain, microscopic hematuria, suspicious ureteral calculi, B-ultrasonography, KUB, and IVU without clinical manifestations were examined by spiral CT and the volumetric images were reconstructed by 3D reconstruction. Results 24 cases of spiral CT showed ureteral calculi, the diagnosis rate was 96%. Three cases of CT three-dimensional imaging showed stones cause renal pelvis, ureteral dilatation and surrounding tissue edema and other secondary changes. Conclusion Spiral CT diagnosis of ureteral stones safe, fast and accurate
