目的：比较静脉肾盂造影(IVP)与CT尿路造影(CTU)对膀胱癌的诊断价值。方法收集46例临床确诊膀胱癌患者的IVU及CTU资料，统计分析IVP与CTU对膀胱癌的诊断符合率及诊断价值。结果 IVP和CTU检查对膀胱癌的诊断符合率分别为65.2豫(30/46)、97.8豫(45/46)，差异具有统计学意义(<0.01)。 IVP可显示膀胱癌并行的上尿路肿瘤和输尿管积水，CTU在此基础上能进一步显示病变周围组织情况以及有无转移等。结论 CTU检查对膀胱癌的诊断价值明显优于IVP检查。“,”Objective To compare the value between Intravenous pyelography and computed tomography urography in diagnosing disease of bladder cancer. Methods Col ect the data from 46 patients (checked by IVP and CTU) with clinical confirmed bladder cancer, then analysis statistical y the diagnostic coincidence rate and diagnostic value between IVP and CTU in diagnosing disease of bladder cancer. Results The diagnostic coincidence rate of diagnosing bladder cancer with IVP and CTU is respectively 65.2%, 97.8%. These dif erences suggest a statistic meaning ( <0.05), IVP can display the upper urinary tract tumor and hydroureter caused by bladder cancer ,and CTU on the basis of further display lesions of sur ounding tissues and metastasis, etc. Conclusion The value of CTU examination in diagnosis of bladder cancer was significantly higher than that of IVP examination.
