摘　　要：目的探讨CEUS鉴别诊断肾脏局灶性高回声良恶性病变的价值。方法回顾性分析56例肾脏单发高回声局灶性病变患者的常规超声(US)及CEUS声像图资料,对其进行定性诊断;以病理诊断为金标准,计算并比较两者的诊断效能。结果 US及CEUS诊断肾恶性高回声病变的敏感度、特异度、阳性预测值、阴性预测值、准确率为70.00%(14/20)、75.00%(27/36)、60.87%(14/23)、81.82%(27/33)、73.21%(41/56)和80.00%(16/20)、94.44%(34/36)、88.89%(16/18)、89.47%(34/38)、89.29%(50/56),CEUS的诊断准确率、特异度和阳性预测值均高于US(P均<0.05)。CEUS结果与病理诊断一致性好(Kappa值=0.761),US与病理诊断一致性一般(Kappa值=0.435)。结论 CEUS可提高对于肾脏局灶性高回声良、恶性肿物的诊断及鉴别诊断效能。Objective To investigate the value of CEUS in differential diagnosis of benign and malignant renal focal hyperechoic lesions. Methods Data of conventional ultrasound （US） and CEUS of 56 patients with single renal focal hyperechoic lesion were retrospectively analyzed, and differential diagnosis of benign and malignant lesions was performed with US and CEUS, respectively. Taking pathological diagnosis as golden standard, the diagnostic efficacy of US and CEUS were calculated and compared. Results The sensibility, specificity, positive predictive value （PPV）, negative predictive value （NPV） and accuracy of US was 70.00% （14/20）, 75.00% （27/36） , 60.87% （14/23）, 81.82% （27/33） and 73.21G （41/56）, while of CEUS was 80.00G （16/20）, 94.44% （34/36）, 88.89% （16/18）, 89.47% （34/38） and 89.29%（50/56）, respectively. The accuracy, specificity and PPV of CEUS were higher than those of US （all P〈0.05）. The consistency of CEUS and pathology was good （Kappa=O. 761）, while of US and pathology was ordinary （Kappa= 0. 435）. Conclusion CEUS can improve differential diagnostic efficacy of renal focal hyperechoic lesions.
