摘要
目的评价二维声像图及彩色多普勒成像(CDI)在小肾癌早期诊断中的应用价值。方法分析30例经病理证实的小肾癌的声像图资料,评价CDI特征与肿瘤病理学改变的相关性。结果 30例中,18例病灶以稍高回声为主,22例病灶边界清楚,22例病灶向肾表面隆起;21例病灶血流丰富,周边多呈环绕型血流信号,并向内部穿入。30例中,24例为肾透明细胞癌,2例为乳头状肾细胞癌,1例为多房囊性肾细胞癌,1例为肾嫌色细胞癌,2例肾盂浸润性尿路上皮癌,均为单侧病变;超声诊断小肾癌的准确率100%。结论超声二维声像图结合CDI对小肾癌的早期诊断及鉴别诊断具有重要临床意义。
Objective To observe the value of two-dimensional ultrasound and color Doppler imaging （CDI） in diagnosis of small renal carcinoma. Methods Ultrasonic and pathological data of 30 patients with small renal carcinoma confirmed by pathology were analyzed. Results Eighteen tumors mainly manifested as slightly higher echo, 22 tumors showed clear boundary, 22 tumors protruded from kidney surface, and 21 tumors displayed rich blood flow signal with mostly circular vascular pattern at peripheral area and penetrating vascular pattern into internal area. There were 24 cases of renal clear cell carcinoma, 2 of papillary renal cell carcinoma, 1 of multilocular cystic renal cell carcinoma, 1 of chromophobe renal cell car- cinoma and 2 cases of renal pelvis invasive urinary epithelia cancer, which were all unilateral lesion. The diagnostic accuracy rate of ultrasonography was 100%. Conclusion Two-dimensional ultrasonography combined with CDI has important clini- cal significance on early diagnosis and differential diagnosis of small renal carcinoma.
