摘　　要：目的　探讨IVU造影辅助CT仿真内窥镜 (CTVC)诊断膀胱肿瘤的临床价值。　方法　经IVU、CT仿真内窥镜检查 2 2例膀胱肿瘤病人 ,获得的图像信息与膀胱镜所见及手术结果比较分析。　结果　 2 2例病人经CTVC发现浅表乳头状瘤 18个 ,结节、团块乳头状瘤 11个 ,浸润性肿瘤1个。肿瘤直径最小 3.0mm。与膀胱镜检查及手术结果完全符合。根据CTVC图像结合断层CT扫描分析参照膀胱镜分型将膀胱肿瘤分为 3型 :(1)浅表乳头状瘤 ,(2 )结节、团块状乳头状瘤 ,(3)浸润性肿瘤。　结论　CTVC是一种新的无创检查方法 ,可以显示直径 >3.0mm突入膀胱的肿瘤和肿瘤表面特征、肿瘤与输尿管口及膀胱颈的关系、膀胱粘膜情况 。Objective To evaluate CT virtual cystoscopy (CTVC) in the diagnosis of bladder tumor. Methods 22 cases of bladder cancer were examined by spiral CTVC with intravenous injection of 60% urografin or omnipaque.The images obtained were compared with that observed on coventional cystoscopy and operation. Results Based on CTVC images and transverse section images of CT,tumors were classified as 3 catogories:(1)superficial papillary tumor.(2)tubercular mass papillary tumor.(3)infiltrated tumor.Of the 22 cases examined with CTVC,18 were papillomas,11 tubercalar mass papillomas and 1 infiltrated tumor.The smallest was 3.0 mm in diameter.CTVC findings have been similar to those observed on conventional cystoscopy and operation. Conclusions CTVC,a new,noninvasive,safe and useful technique,can correctly demonstrate the details of surface of bladder tumor when the latter was greater than 3.0 mm. It could show the normal or abnormal mucosal folds and the relationship of the tumor to the ureteral orifices and the bladder neck.CTVC my be helpful in the choosing of management,in the clinical staging and diagnosis of bladder tumor.
