1.临床资料 40例经手术病理证实的肾癌患者,术前均进行了X线静脉肾盂排泄造影、B型超声、CT扫描,其中一例还进行了肾动脉造影和肾盂造影检查。通过对各种影像所见及诊断结果进行对照分析,对肾癌的正确诊断率本组的结果为肾盂静脉造影52.5%、B超87.5%、CT92.5%。本文探讨影像诊断肾癌的价值认为:肾盂静脉排泄造影能直观全尿路形态,了解双侧性肾脏功能,为一种常规的检查方法,但对小肾癌及边缘性肾癌可出现阴性结果,多数病例还出现患侧肾显影不良或不显影的表现,其敏感性与特异性均较差,若单独应用此项检查会致肾癌误诊甚至漏诊可能。 B型超声对肾脏可行三种切位显像,能较准确显示肾癌肿块大小、形态、轮廓,并能反映出肿块与周围组织的关系,对较大肿块能明确范围,敏感性较好,无损伤又价廉,对临床疑诊肾癌病例是种简便易行较准确的检查
1. Clinical data 40 cases of renal cell carcinoma confirmed by surgery and pathology were preoperative X-ray venous drainage, B-mode ultrasound and CT scan, of which one case also underwent renal artery angiography and pyelography. Through a variety of images seen and diagnostic results of the control analysis of the correct diagnosis of renal cell carcinoma in this group results of renal pelvis vein angiography 52.5%, B-87.5%, CT92.5%. This article discusses the diagnostic value of imaging renal cell carcinoma that: renal pelvis and vein venography can visualize the entire urinary tract morphology, bilateral renal function, as a routine test, but small renal cell carcinoma and marginal renal cell carcinoma may have negative results , Most cases also showed poor performance of ipsilateral renal development or non-imaging performance, the sensitivity and specificity are poor, if the application of this test alone will lead to misdiagnosis and even misdiagnosis of renal cell carcinoma may be. B-mode ultrasound on the kidney feasible three incision imaging, can more accurately display the size, shape, contour of renal cell carcinoma, and can reflect the relationship between the mass and surrounding tissue, the larger the tumor can be a clear range, the sensitivity is better, No damage and inexpensive, the clinical suspicion of renal cell carcinoma is a kind of simple and easy to conduct more accurate examination
