Sonography was utilized to assess six patients with renal transitional cell carcinoma and was correlated with gross pathology in five cases. The neoplasms were seen as discrete, solid masses causing separation of the central renal sinus echoes. The echogenicity of the tumors and the renal parenchyma was similar, but the neoplasms were separated from the renal parenchyma by a linear echogenic zone of renal sinus fat. Pelvicaliceal blood clots, when markedly echogenic, could be differentiated from transitional cell carcinomas. Sonography contributed most in evaluating unilateral nonvisualized kidney or in the presence of nonfilling of the affected pelvicalices on excretory urography.
超声检查用于评估6例肾移行细胞癌患者，并与5例患者的大体病理结果进行对照。肿瘤表现为离散的实性肿块，导致肾窦回声分离。肿瘤与肾实质的回声相似，但肿瘤与肾实质之间被肾窦脂肪的线性高回声带分隔。肾盂肾盏血凝块在回声明显增强时，可与移行细胞癌相鉴别。超声检查在评估单侧肾不显影或排泄性尿路造影时患侧肾盂肾盏未显影的情况中作用最大。
