目的:分析膀胱癌的CT表现,探讨CT对膀胱癌如何治疗的作用要点。方法:对100例临床可疑膀胱肿瘤的患者做CT扫描,其中男90例,女10例,平均年龄63岁。全部病例均经手术病理证实,其中94例为膀胱癌,2例前列腺增生,4例慢性膀胱炎症。结果:CT检出92例膀胱癌,敏感性为97.9%,4例慢性膀胱炎症误诊为膀胱癌,特异性为33%,准确性为94%。92例膀胱癌CT分期与病符合72例,准确率78.3%。结论:CT对膀胱壁内浸润程度的区分不够满意,即对癌肿早期分期的准确性受到一定的限制,但对壁外浸润和盆腔侧壁蔓延的估计较准确,并可显示盆腔内肿大的淋巴结,这样对指导手术有其重要的临床意义。
Objective: To analyze the CT manifestations of bladder cancer and to explore the key points of CT on how to treat bladder cancer. Methods: CT scan was performed on 100 patients with suspected bladder cancer, including 90 males and 10 females, with an average age of 63 years. All cases were confirmed by surgical pathology, of which 94 cases of bladder cancer, 2 cases of benign prostatic hyperplasia, 4 cases of chronic bladder inflammation. Results: CT was detected in 92 cases of bladder cancer with a sensitivity of 97.9%. Four cases of chronic cystitis were misdiagnosed as bladder cancer with a specificity of 33% and an accuracy of 94%. 92 cases of bladder cancer staging and 72 cases of disease, the accuracy rate of 78.3%. Conclusion: CT is not satisfied with the distinction of the degree of infiltration in the bladder wall, that is, the accuracy of the early staging of the cancer is limited, but it is more accurate to estimate the infiltration of the wall and the spread of the lateral wall of the pelvis, Of the lymph nodes, so that has important clinical significance of guiding surgery.
