摘　　要：目的探索数字化图像诊断泌尿系统疾病的应用及意义。方法将ＩＶＵ胶片通过扫描仪转换为数字化图像，对１００例泌尿系统疾病的诊断作数字化图像与原始ＩＶＵ的比较，其中结石２９例、肿瘤４２例、囊肿５例、结核２例、先天性畸形５例、前列腺增生９例、其它８例。结果数字化图像与原始ＩＶＵ的诊断正确率分别为８８％和９１％，差异无显著性（Ｐ＞０．０５）。诊断可信度分别为４．６分和４．８分，图像质量为４．６分和４．８分，诊断难度为１．７分和１．５分，差异均有非常显著性（Ｐ＜０．０１）。结论数字化图像与原始ＩＶＵ胶片对泌尿系统疾病诊断正确率无明显差别，有益于远程会诊和教育。Objective To assess the efficacy of digital image in the detection of urinary diseases. Methods A total of 100 IVU films were digitalized on a laser scanner.There were 29 cases of urolithiasis,42 tumors,5 cysts,2 tuberculosis,5 congital anomalies,9 BPH and 8 others. Results The diagnosis accuracy was 88% for digital images and 91% for IVU films,being statistically insignificant ( P >0.05).The confidence in the diagnosis was 4.6 and 4.8,the image quality being 4.6 and 4.8 and the difficulty in diagnosis 1.7 and 1.5( P <0.01). Conclusions There was no obvious difference in the accuracy of diagnosis of urinary diseases between digital image and the IVU films and the fact has been of great value in telemedicine and teleeducation.
