目的 探讨多层螺旋CT尿路造影 对膀胱疾病的诊断应用价值。方法 利用 多层螺旋CT 机对34例患者CTU图像结果 进行分析，从CTU对膀胱疾病患者的确诊 率、CTU平扫、CTU多期增强和CTU后期的 重建技术分析多层螺旋CTU对膀胱疾病的 诊断应用价值。结果 34例患者通过CTU 检查出共34个病灶，CTU对膀胱疾病的 确诊率为97.14%(34/35)，其中膀胱结核 1(2.94%)个，膀胱结石13(38.23%)个，膀 胱肿瘤6(17.64%)个，膀胱憩室4(11.76%) 个，前列腺增生10(29.41%)个。CTU平 扫、多期增强、后重建技术能对膀胱憩室 进行很好的图像显示，能直观的观察膀胱 与周围器官的解剖结构。结论 多层螺旋 CTU技术能多角度立体的显示膀胱解剖结 构，操作简单、无创伤、适应人群广、诊 断准确性高，能为临床手术提供影像资 料。

Objective Investigate the applied value analysis of multi slice spiral urinary tract to diseases of urinary bladder. Mothods Make the advantage of Multi slice spiral, analyze the image result of 34 patients. From the diagnosis rate of ctu to patients with bladder disease, CTU plain scan, CTU multi phase enhancement, analysis of the reconstruction technique in the later period of CTU, Multi slice spiral CTU in the bladder diseases. Results The 34 patients check out 34 nidus through the CTU.the diagnosis rate of ctu to bladder disease is 97.14%.The cystophthisis is 1 (2.94%).The cystolith is 3 (38.23%). The tumor bladder is 6 (17.64%), the diverticulum of bladder is 4 (11.76%). The Benign prostatic hyperplasia is 10 (29.41%). CTU scan, multiphase enhancement, reconstruction have good image to the vesical diverticulum,could observe the anatomy of the urinary bladder and the surrounding organs. Conclusion Multi-layer spiral CTU technology can display the bladder multi-angle stereo anatomy, simple operation, no wound, to adapt to the crowd and diagnosis accuracy is high, can provide clinical surgery with image data.
