The reliability of radiologic diagnosis was studied in 99 patients undergoing ultrasonography, computerized tomography and angiography in work up of renal mass lesions. The diagnoses were confirmed by angiography combined with percutaneous puncture or by surgery. Of the lesions, 37 were simple renal cysts and 56 were renal cell carcinomas. Eighty-eight percent were diagnosed correctly by ultrasonography, 96% by computerized tomography and 84% by angiography. The conclusion is that the radiologic evaluation of a renal mass lesion found at urography should start with ultrasonography. Percutaneous puncture is not recommended if all criteria of a simple renal cyst are strictly fulfilled at ultrasonography. In all other cases a computerized tomography is thought to be mandatory to avoid false negative diagnoses of malignant tumours or other diseases which may need therapy. In some patients a combination with angiography and percutaneous puncture is advised to establish a diagnosis prior to surgery.
对99例接受超声检查、计算机断层扫描和血管造影以评估肾肿块病变的患者进行了放射学诊断可靠性的研究。诊断通过血管造影结合经皮穿刺或手术得以证实。这些病变中，37例为单纯性肾囊肿，56例为肾细胞癌。超声检查正确诊断率为88%，计算机断层扫描为96%，血管造影为84%。结论是，对尿路造影中发现的肾肿块病变进行放射学评估应从超声检查开始。如果超声检查严格符合单纯性肾囊肿的所有标准，则不建议进行经皮穿刺。在所有其他情况下，认为必须进行计算机断层扫描以避免对可能需要治疗的恶性肿瘤或其他疾病的假阴性诊断。在一些患者中，建议结合血管造影和经皮穿刺以在手术前确立诊断。
