| 摘 要： | Objective To study the practical value of 3-dimensional computed tomography on diagnosis of bladder tumor, Methods Fifteen patients with bladder masses were examined by thin-layer computed tomography. The results of 3-dimensional reconstructed images were compared with the final diagnosis and the pathological stages. Results According to 3-dimensional reconstructed images, among the 15 cases, 12 cases of bladder cancer were diagnosed, and the pathological types were transitional carcinoma. Two cases were diagnosed as benign tumor (leiomyoma), and the other one was colon cancer, which invaded bladder. The accuracy was 100% . The clinical stages were determined. Of the 12 bladder carcinomas,5 was in stage T1, 3 in T2,, 3 in T3 and 1 in T4.The accuracy of staging was up to 83% (10/12) compared with pathological stages. Conclusion The 3-dimensional reconstructed technology may improve the accuracy of staging of bladder carcinoma, and to provide important evidence for surgery options. 3 refs,2 figs.
