超声造影在肾细胞癌临床诊断中的应用价值

目的 通过观察肾细胞癌的超声造影表现,以探讨超声造影对肾细胞癌的临床诊断价值.方法 分析106例经手术和病理检查证实的肾细胞癌患者的常规超声及超声造影资料,比较两种方法对肾细胞癌假包膜的显示能力.结果 106例肾细胞癌中,肾透明细胞癌98例,多房性囊性肾细胞癌3例,乳头状肾细胞癌5例.超声造影显示假包膜80例(75.4％),而常规超声显示假包膜29例(27.3％),超声造影及常规超声均不显示假包膜26例,两者间差异有统计学意义(P＜0.01).结论 超声造影对肾细胞癌假包膜显示率明显高于常规超声,超声造影对诊断肾细胞癌有重要的临床价值.

Application of ultrasonic contrast in renal cell carcinoma diagnosis

Objectives To observe the performance of renal cell carcinoma with contrast-cnhanced ultrasound(CEUS) ,and to assess clinical application value of CEUS.Methods 106 RCC patients underwent conventional ultrasonography and CEUS were analyzed retrospectively.The visualization rate of pseudocapsule of the tumors were compared between the two methods.Results Final diagnosis results were as follows:renal cell carcinomas 98, Multilocular cystic renal cell carcinomas 3, papillary renal cell carcinomas 5.Pseudocapsule was detected in 29 cases (27.3％) with conventional ultrasound and in 80 cases (75.4％) with CEUS, which was a significant difference (P ＜ 0.01).The pseudocapsule in 26 cases was not visible with either conventional or CEUS.Conclusions CEUS is more effective in the detection of pseudocapsule than conventional ultrasound and may be vital useful in diagnosis of renal cell carcinoma.
