From 1982 to 1985, 225 patients with renal cell carcinoma were treated by nephrectomy. To evaluate the diagnostic significance of ultrasonography in predicting tumor stage the results of ultrasonography, computerized tomography, renal angiography and excretory urography were compared to the histopathological findings. Since local tumor extension has a considerable impact on the operation strategy evaluation of the T classification was of particular interest. All 4 diagnostic procedures were performed in 73 of the 225 patients. The T stage was determined correctly by ultrasonography in 77.8 per cent of the patients, while the tumor was not identifiable in only 0.6 per cent. Computerized tomography was almost as reliable as ultrasonography (the T stage was predicted correctly in 72.3 per cent of the examinations). In contrast, the tumor was staged correctly by angiography in only 57.2 per cent of the patients and by excretory urography in only 59.2 per cent. From these results ultrasonography appears to be an effective, noninvasive, inexpensive and safe procedure to evaluate the T stage of renal tumors.
1982年至1985年期间，225例肾细胞癌患者接受了肾切除术治疗。为评估超声检查在预测肿瘤分期方面的诊断意义，将超声检查、计算机断层扫描、肾血管造影和排泄性尿路造影的结果与组织病理学检查结果进行了比较。由于局部肿瘤扩展对手术策略有相当大的影响，因此对T分类的评估尤为重要。225例患者中有73例接受了所有4种诊断检查。超声检查对T分期的判断正确率为77.8%，仅0.6%的患者无法识别肿瘤。计算机断层扫描的可靠性与超声检查相近（72.3%的检查能正确预测T分期）。相比之下，血管造影对肿瘤分期的正确率仅为57.2%，排泄性尿路造影为59.2%。基于这些结果，超声检查似乎是一种评估肾肿瘤T分期的有效、无创、廉价且安全的方法。
