33 kidney tumours were detected in 15,500 routine scans of the upper abdomen. 13.7 per cent of these tumours were asymptomatic at the time of diagnosis. The size of these accidentally detected tumours was evidently smaller than in the case of symptomatic ones and the patients were younger at the time of diagnosis. The diagnosis was falsely positive in one case and falsely negative in 3 cases. In 2 cases of incorrect negative findings the sonographic diagnosis was hydronephrosis, but IVP and cytology of the specimen proved that these tumours were urothelial carcinomas. Apparently the weak point in sonographic diagnosis is the diagnosis of urothelial carcinomas. In cases of suspected kidney tumour or a sonographic diagnosis of hydronephrosis additional diagnostic methods must be undertaken. Our results show that adequate and cost-effective diagnostic information in the detection of kidney tumours is obtained in the majority of cases by sonography and urography.
在15500次上腹部常规扫描中检测到33例肾肿瘤。这些肿瘤中有13.7%在诊断时无症状。这些意外发现的肿瘤大小明显小于有症状的肿瘤，且患者诊断时年龄更小。诊断有1例假阳性和3例假阴性。在2例假阴性结果中，超声诊断为肾积水，但静脉肾盂造影和标本细胞学检查证明这些肿瘤是尿路上皮癌。显然，超声诊断的弱点在于尿路上皮癌的诊断。在怀疑肾肿瘤或超声诊断为肾积水的情况下，必须采用其他诊断方法。我们的结果表明，在大多数情况下，通过超声检查和尿路造影可获得足够且具有成本效益的肾肿瘤检测诊断信息。
