Ultrasonography (US) was utilized to assess 22 patients with renal pelvic carcinomas, The neoplasms were demonstrated as hypoechoic mass in 81.82%, and as visualized hyperechoic mass in 18.18%; Their echogenicity was highly correlated with gross pathology. Among all the cases, 5 patients were investigated with color Doppler Flow Imaging (CDFI), and none of them demonstrated the high-frequency Doppler shifted signals seen in renal cell carcinomas. Therefore CDFI may help to differentiate renal pelvic carcinomas from renal cell carcinomas.
采用超声检查（US）对22例肾盂癌患者进行评估。肿瘤在超声下表现为低回声肿块的占81.82%，表现为高回声肿块的占18.18%；其回声特征与大体病理高度相关。所有病例中，5例患者接受了彩色多普勒血流成像（CDFI）检查，均未显示出肾细胞癌中可见的高频多普勒频移信号。因此，CDFI有助于鉴别肾盂癌和肾细胞癌。
