摘　　要：目的探讨术前超声造影能否预测肾脏占位病变的组织类型。方法 27例肾脏占位病变患者术前行灰阶超声、彩色多普勒、八氟丙烷超声造影,超声造影结果与外科病理结果相比较。结果 18例患者为透明细胞癌,3例为1型乳头状瘤,1例为嫌色细胞癌,1例为未分类病变,3例为嗜酸细胞瘤,1例为良性血管肌脂肪瘤。不均匀回声和延迟洗出相联合、造影增强度、病变峰值强度联合延迟洗出诊断肾占位病变病理类型有高的的阳性预测值、敏感度和特异度。结论不均匀回声、延迟洗出、造影增强度、病变峰值强度有助于鉴别诊断肾透明细胞癌和非透明细胞癌。Objective To evaluate the values of contrast-enhanced ultrasound in prediction pathologic types of renal occupied lesions. Methods 27 patients with renal occupied lesions underwent octafluoropropane contrast-enhanced ultrasound and gray-scale,Doppler ultrasound. Ultrasound reports and pathologic results were compared. Results Gray- scale heterogeneity and delayed lesion washout,diminished lesion enhancement grade combining delayed washout had great positive predictive value,sensitivity,and specificity in prediction pathologic types of renal occupied. Conclusion Contrast- enhanced ultrasound may be useful for differentiating pathologic types of renal occupied lesions.
