作者分析了近２年来的９３例肾癌病例，认为：４０～７０岁是肾癌的高发年龄，肾癌的发病与吸烟有直接关系，并且发现肾癌患者常并发高血压。Ｂ超是筛选肾癌的首选检查方法，小肾癌ＣＴ有其特殊表现，鉴别、处理小肾癌要小心谨慎，切不可盲目切除肾脏。虽然Ｂ超、ＣＴ、ＭＲＩ确诊率高，但仍有误诊可能，说明影像学检查结果与病理学检查结果仍有一定差距。因肾癌Ⅰ、Ⅱ期手术效果较好，所以，早期诊断是关键。认为中老年定期体检是十分必要的。
The authors analyzed 93 cases of renal cell carcinoma in recent 2 years and concluded that the age of 40 to 70 years old is the most common cause of renal cell carcinoma. The incidence of renal cell carcinoma is directly related to smoking, and patients with renal cell carcinoma are often found to have hypertension. B ultrasound screening is the preferred method of screening for renal cell carcinoma, small renal cell carcinoma CT has its special performance, identification, treatment of small renal cell carcinoma to be cautious, must not blindly remove the kidneys. Although B ultrasound, CT, MRI diagnosis rate is high, but there are still possible misdiagnosis, imaging findings and pathological examination results still have some gaps. Due to kidney cancer Ⅰ, Ⅱ surgery is better, so early diagnosis is the key. It is very necessary to consider regular physical examination in middle-aged and elderly people.
