肾癌的超声声像图与组织病理结构的相关性分析

Correlative Analysis of Renal Carcinomas’Ultrasonography and Pathologic Structure

目的:探讨不同病理组织结构肾癌的超声声像图表现,以提高超声对声像图表现不典型肾癌的超声诊断准确率。材料和方法:回顾性分析120例患者的123例肾癌和13例患者肾错构瘤的超声声像图特征,以无回声、低回声、高回声和强回声进行分类,并结合术后组织病理结果相对照。结果:123例肾癌中肾透明细胞癌117例,肾乳头状细胞癌2例,移形细胞癌2例,肾母细胞癌1例,非霍奇金淋巴瘤1例。121例肾恶性肿瘤声像图表现:无回声3例,低回声77例,高、强回声41例。13例肾错钩瘤均为高、强回声。结论:肾癌的声像图以低回声为主,部分可伴囊变,钙化,部分肾癌会出现高,强回声,是引起超声诊断错误的原因之一。

Purpose： To increase the diagnosis rate of atypical renal carcinomas by analyzing their ultrasonography with certain pathologic structure. Materials and methods： we retrospectively analyzed ultrasonography of 123 cases of renal carcinomas in 120 patients, and 13 cases of renal hamartomas. We divided patients into anechoic, hypoechonic, hyperechonic and extra- hyperechoic groups. And compared their ultrasonography with postoperative pathologic report. Results： Pathologic examination reported 123 cases of renal carcinoma, including 117 cases of clear cell carcinoma, 2 cases of papillary carcinoma, 2 cases of transitional cell carcinoma, 1 case of nephroblastoma and 1 case of NHL. Their ultrasonography including： 3 cases of anechoic mass, 77 cases of hypoechoic mass, 41 cases of hyperechoic mass. All of 13 cases of kidney hamartomas have hyperechoic ultrasonography. Conclusion： Most renal carcinomas have hyperechoic sonography, some with cystic changes or calcification. Those with hyperechoic ultrasonography are always misdiagnosed.
