目的分析肾脏恶性肿瘤的二维及彩色多普勒超声表现,提高对肾脏恶性肿瘤的诊断水平。方法回顾性分析本院2005～2010年由超声首诊并经手术后病理证实的28例肾脏恶性肿瘤的影像学资料。结果 28例肾脏肿瘤中,27例行根治性肾切除术,1例行肾局部剜除术。由超声首诊为肾脏恶性肿瘤的27例,1例误诊为肾盂炎性病变。24例为肾透明细胞癌,1例未分化癌,1例颗粒细胞癌,1例囊性肾癌,1例肾盂移行上皮细胞癌。定性诊断符合率96.4%,定位诊断符合率96.4%。结论彩色多普勒超声适宜作为筛查肾脏恶性肿瘤的首选方法。
Objective To analyze the two-dimensional and color Doppler ultrasonography of renal malignant tumors and to improve the diagnosis of renal malignant tumors. Methods We retrospectively analyzed the imaging data of 28 cases of renal malignancies confirmed by pathology in our hospital from 2005 to 2010. Results In 28 cases of renal tumors, 27 cases underwent radical nephrectomy and 1 case underwent partial nephrectomy. Twenty-seven cases were diagnosed with renal malignancy by ultrasound, and one case was misdiagnosed as pyelofemoral disease. 24 cases were clear cell renal cell carcinoma, 1 case of undifferentiated carcinoma, 1 case of granular cell carcinoma, 1 case of cystic renal cell carcinoma and 1 case of renal pelvis transitional cell carcinoma. Qualitative diagnosis coincidence rate of 96.4%, positioning diagnosis coincidence rate of 96.4%. Conclusion Color Doppler ultrasound is the best method to screen renal malignant tumors.
