摘要
本文总结分析了经手术病理证实的２２例肾盂癌的超声表现，结果表明肾盂癌的声像图分两种类型，即低回声型（占８１．８２％）和强回声型（占１８．１８％），其回声水平与肿瘤内出血、坏死程度密切相关。同时，分析了其中５例肾盂癌彩色多普勒血流显像（简称彩超）的表现，发现肾盂癌病灶内缺乏高速动脉血流信号，而此类血流信号通常可在肾细胞癌中检出，因此认为彩超对鉴别从部位上难以区分的肾细胞癌与肾盂癌有较大帮助。
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.A-mong 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 cellcarcinomas.Therefore CDFI may help to differentiate renal pelvic carcinomas from renal cellcarcinomas.
