摘　　要：目的评价螺旋CT对原发性膀胱移行细胞癌(TCC)分期的准确性。方法对2000年9月-2009年9月诊治的73例原发性TCC患者,手术前行螺旋CT临床分期与手术后病理分期进行比较。结果 TCC患者手术前螺旋CT临床分期与手术后病理分期相符率为90.5%。7例分期不符的患者中,4例螺旋CT分期低于病理分期,3例高于病理分期。结论螺旋CT对TCC的手术前临床分期较准确;螺旋CT分期误差产生的主要原因是不能确定肿大的淋巴结是否是癌转移。Objective To investigate the value of contrast helical CT in Neopl-asm staging in patients with transitional cell carcinoma （ TCC） of bladder. Methods Total 73 patients with TCC of bladder treated from september 2000 to September 2009 was analysed to compare preoperative helical CT examination with postoperative pathological diagnosis. Results The coincident staging of helical CT and pathological finding of TCC of bladder was found to be 90. 5%. In the remaining seven patients,four patients were of overstaging and three patients were of understaging respectively. Conclusion The early enhancing phase of helical CT is helpful in the evaluation of the staging in patients with TCC of bladder. The cause of incorrecting staging by preoperative CT was usualy due to the difficulty in determing if lymph nodemetastasis occurs.
