目的：探讨彩色多普勒超声在诊断膀胱癌的临床应用价值。方法回顾性分析经膀胱镜或手术病理确诊为膀胱癌的36例患者的超声资料，超声诊断结果与病理结果作对比分析。结果超声诊断膀胱癌诊断符合率91.7%(33/36)。结论彩色多普勒超声对膀胱癌诊断具有较高的准确性，同时具有方便、简捷、无创、可重复性强等优点，特别是CDFI的应用更提高了超声诊断符合率。“,”Objective To explore the value of color Doppler ultrasound in diagnosis of bladder carcinoma. Methods Ultrasonic data of 36 bladder cancer patients which were diagnosed by pathology of cystoscope or operation were retrospectively analyzed. The result of ultrasound diagnosis were contrasted with the result of pathology. Results The diagnosis coincidence rate of ultrasound diagnosis of bladder cancer was 91.7% (33/36). Conclusion Color Doppler ultrasound has the higher accuracy in diagnosis of bladder cancer, and has the advantages of convenient, simple, non-invasive and repeatable. Especially the application of CDFI improves the coincidence rate of ultrasound diagnosis.
