肾母细胞瘤的超声诊断

目的　评价超声诊断肾母细胞瘤的临床价值。方法　回顾性分析 46例病理证实的肾母细胞瘤的超声资料。结果　肾母细胞瘤超声诊断正确率为 91.30 % ,超声分期正确率为 80 .43%。超声表现为不均质低回声为主且常伴液化坏死的实性肿块 ,49%的肿块内部显示散在点状强回声 ,部分伴声影。彩色多普勒超声显示肿瘤血供丰富 ,内部常探及高速、高阻动脉样血流 ,RI值 >0 .63有较高的诊断价值。 46.81%的病例可以显示残余肾脏 ,且残肾基本无血供。结论　超声诊断正确率较高 ,能为临床提供极有价值的影像学信息 ,应成为首选的影像学检查方法

Diagnosis Value with Ultrasonic Inaging of Nephroblastoma

Objective To evaluate the clinical value of ultrasonic diagnosis on nephroblastoma.Methods The ultrasonic manifestations of 46 cases of nephroblastoma confirmed by surgery and pathology were studied retrospectively.Results The Correct diagnosis rate of nephroblastoma was 91.30% with ultrasonic imaging,and the correct staging rate was 80.43%. Most sonogram of nephroblastoma were heterogeneous solid echos with liquefaction and necrosis.In 49% tumours,the images showed the diffuse strong point echos,and part with acoustic shadow.The color Doppler flow imaging showed the blood provision was plentiful in tumor,and the high speed and high resistance index arteria blood stream could be detected by pulsed wave Doppler in interior of tumor.The RI above 0.63 was value for diagnosis.The residual kidney could be showed in 46.81% cases,and the blood provision hardly could be detected.Conclusions Ultrasonic diagnosis which could provide important information should be the principal screenage examination method for nephroblastoma.
