Seventy-two patients with solid renal lesions were studied by renal echography and the echography and the results were correlated with angiography and pathologic examination of excised specimens. Thirty-one tumors were diagnosed by echography and were proved by angiography and pathology. Renal tumors are either more echo-producing or less echogenic than adjacent normal renal parenchyma. All angiographically hypervascular tumors and hypovascular tumors with areas of hemorrhage and necrosis are more echo-producing. Hypovascular homogenous renal carcinomas, transitional cell carcinoma invading the kidney, and metastases are less echo-producing. Pseudo-tumors have the same echo characteristics as surrounding and adjacent normal renal parenchyma.
对72例有实性肾病变的患者进行了肾脏超声检查，并将超声检查结果与血管造影及切除标本的病理检查结果进行了对比。超声检查诊断出31个肿瘤，这些肿瘤经血管造影和病理检查得到证实。肾肿瘤与相邻正常肾实质相比，要么产生更多回声，要么回声更低。所有血管造影显示为高血管性的肿瘤以及伴有出血和坏死区域的低血管性肿瘤产生更多回声。低血管性均匀性肾癌、侵犯肾脏的移行细胞癌以及转移瘤产生较少回声。假性肿瘤与周围及相邻正常肾实质具有相同的回声特征。
