目的 研究螺旋CT增强扫描在膀 胱癌术前分期中的临床价值。方法 选 取我院2013年3月到2016年3月泌尿科的 可疑浸润性膀胱癌患者51例，术前行多 层螺旋CT检查(动态增强扫描、平扫)， 手术后病理证实，将术前的CT检查结果 和术后的病理结果在进行对照对比。结 果 51例可疑浸润性膀胱癌患者共发现 癌灶57个，其中癌灶的术前CT扫描分期 和术后病理分期T1(5/5)、T2a(9/9)、 T2b(11/11)、T4b(1/1)的相符率为100%， T3a、T3b、T4a与术后病理分期相符率为 63.6%(7/11)、75%(9/12)、75%(6/8)，术 前CT扫描分期和术后病理分期膀胱癌分期 的的对照相符率82.45%(48/57)。结论 螺 旋CT增强扫描在膀胱癌术前分期具有较高 的准确性，螺旋CT薄层动态增强扫描可作 为膀胱癌的常规检查。

Objective To investigate the clinical effect of spiral CT enhancement scanning on preoperative staging of bladder cancer. Methods 51 cases with suspected invasive bladder cancer in our hospital from March 2013 to March 2016 were selected. They were given spiral CT enhancement scanning before surgery and pathological studies after surgery. Compare the CT examination results and pathological examination results. Results Of 51 cases with suspected invasive bladder cancer, 57 neoplastci foci were found. Preoperative ctscanning stage and pathological TNM: T1(5/5), T2a(9/9), T2b(11/11), T4b(1/1), the corresponding rate was 100%, T3a, T3b, T4acorresponding rate were 63.6%(7/11), 75%(9/12), 75%(6/8). Contrast match rate of preoperative ctscanning stage and pathological TNM was 82.45%(48/57). Conclusion Spiral CT enhancement scanning has higher accuracy on preoperative staging of bladder cancer and spiral CT thin layer dynamic enhanced scan can be used as routine inspection.
