目的探讨肾细胞癌的超声声像图特点,进一步提高对本病的检出和诊断率。方法对经手术和病理证实21例肾细胞癌的超声声像图特点进行回顾性分析。结果肾细胞癌多数体积较小,边界清,向外突出引起肾脏形态改变,内部血流信号丰富;肿瘤回声多样,呈低回声、中等回声、中强回声或混合回声。结论随着超声仪器分辨率的提高,对无症状肾肿瘤特点的认识也不断提高,在大量健康人群进行体格检查中,超声是发现肾细胞癌的重要手段。
Objective To investigate the ultrasonographic features of renal cell carcinoma to further improve the detection and diagnosis of this disease. Methods The echographic features of 21 cases of renal cell carcinoma confirmed by operation and pathology were retrospectively analyzed. Results The majority of renal cell carcinoma was small in size, with clear border and outward protrusion, which caused the change of kidney morphology and abundant internal blood flow signals. The tumor echo varied with low echo, moderate echo, moderate echo or mixed echo. Conclusion With the improvement of the resolution of ultrasound instruments, the awareness of the characteristics of asymptomatic renal tumors has also been continuously improved. Ultrasound is an important means of detecting renal cell carcinoma in the physical examination of a large number of healthy people.
