摘　　要：目的 探讨超声造影对囊性肾肿物诊断价值. 方法 按照影像诊断标准,对29例囊性肾肿物的常规超声、超声造影、增强CT诊断结果进行分级,与最终诊断结果比较,应用受试者工作特征（ROC）曲线进行分析.男15例,女14例,年龄18～63岁.肿瘤位于左肾13例,右肾16例.29例均行常规超声检查后1～3 d行超声造影及增强CT检查. 结果 29例中20例有病理结果,其中恶性18例、良性2例.其余9例中失访1例,8例随访6～12个月,经超声或增强CT检查,病灶无明显变化.常规超声、超声造影与增强CT对囊性肾肿物分级的ROC曲线下面积分别为0.721、0.997、0.997,超声造影与常规超声比较差异有统计学意义（P=0.003）,与增强CT比较差异无统计学意义（P=1.000）.结论 超声造影对于囊性肾肿物诊断效果优于常规超声,与增强CT相似,可以应用Bosniak诊断系统对囊性肾肿物进行评价.Objective To investigate the value of contrast enhanced ultrasonography in evaluating cystic renal mass. Methods According to the imaging diagnosing standard, 29 cystic renal mass lesions were studied with contrast enhanced ultrasonography（CEUS）, unenhanced ultrasonography （US）, contrast enhanced CT（CECT） and then correlated their results with final histopathological results. The data were tested by receiver operating characteristic（ROC） curve. Results The area under ROC curve of CEUS and US was 0. 721, 0. 997, respectively. There was significant difference between the 2 groups （P=0. 003）. The area under ROC curve of CEUS and CECT was 0. 997, 0. 997,respectively. There was no significant difference between the 2 groups （P= 1. 000）. Conclusions CEUS is better than US and similar to CECT in evaluating cystic renal mass. CEUS with the Bosniak classification is useful for evaluating cystic renal mass.
