摘　　要：目的探讨CTU结合常规CT在2.0cm以下肾盂移行细胞癌诊断中价值。方法回顾性分析经手术病理证实的2.0cm以下肾盂移行细胞癌31例常规CT和CTU表现,研究两种方法对本瘤检出率。结果肿瘤位于肾盂15例,肾盏9例,肾盂与输尿管交接部7例。肿瘤呈结节状充填肾盂或肾盏28例,沿肾盂表面浸润生长3例。肿瘤最大直径1.1-2.0cm,其中1.5cm以下8例,1.6-2.0cm20例,仅见肾盂壁界限性结节状增厚3例。敏感度常规CT为80.6%,CTU为90.3%;准确度常规CT为54.8%,CTU为77.4%。结论本组研究显示CTU结合常规CT能提高诊断准确率。Objective To study on CTU combined with conventional CT diagnostic value in transitional cell carcinoma of renal pelvis in below 2.0cm.Methods We retrospective analysed of below 2.0cm proved by operation and pathology following renal pelvic transitional cell carcinoma in 31 cases of conventional CTU and CT manifestations,studied of two methods in detection of the tumor.Results The tumors located in the renal pelvis in 15 cases,renal pelvis in 9cases,renal pelvis and ureter in 7cases.The tumor was nodular filling kidney or renal calices in 28 cases,renal pelvis surface infiltration growth in 3cases.Maximum tumor diameter ranged from 1.1to 2.0cm,in which below 1.5cm was 8cases,1.6-2.0cm 20 cases,3cases were nodular thickening of the pelvic wall boundaries.The sensitivity of the conventional CT was 80.6%,CTU 90.3%.The accuracy of conventional CT was 54.8%,CTU 77.4%.Conclusion The results showed that CTU combined with conventional CT significantly improved the accuracy of diagnosis.
