目的评价彩色多普勒超声显像对肾癌的诊断价值。方法回顾性分析79例肾癌患者的彩超多普勒诊断结果。结果二维超声结合CDFI所见,肾透明细胞癌66例中,超声诊断正确49例(74.2%),不能确定性质17例(25.8%)。13例肾血管平滑肌脂肪瘤,9例声像图较典型,超声诊断正确。4例体积较大者,二维声像图是混合回声,超声诊断为多囊肾,病理见肾血管平滑肌脂肪瘤内部出血坏死严重。结论彩超多普勒对肾脏占位性病变的诊断率非常高,它不仅能鉴别肾脏弥漫性病变和局灶性病变,确定癌肿的大小和范围,显示癌肿与肾血管和周围脏器的关系,并且能了解是否有转移,对肾癌的分期、手术方案的制定及估计预后等有重要意义。
Objective To evaluate the diagnostic value of color Doppler ultrasonography in renal cell carcinoma. Methods Retrospective analysis of 79 cases of renal cell carcinoma by Doppler ultrasound diagnosis. Results Two-dimensional ultrasound combined with CDFI showed that in 66 cases of clear cell renal cell carcinoma, 49 cases (74.2%) were correctly diagnosed by ultrasound and 17 cases (25.8%) were not confirmed by nature. Thirteen cases of renal angiomyolipoma, nine cases of typical ultrasonography, ultrasound diagnosis is correct. 4 cases of larger volume, two-dimensional sonography is a mixed echo, ultrasound diagnosis of polycystic kidney disease see renal angiomyolipoma severe hemorrhage and necrosis. Conclusion Doppler ultrasound diagnosis of kidney space-occupying lesions is very high, it can not only identify diffuse renal lesions and focal lesions, to determine the size and scope of cancer, showing the relationship between cancer and renal vessels and the surrounding organs Relationship, and can understand whether there is transfer, the staging of renal cell carcinoma, the development of surgical options and prognosis of prognosis of great significance.
