The place of whole-lung tomography in urologic malignancy has not been established. We reviewed 88 cases of known or suspected urologic malignancy in which tomography was used. Most patients had renal, bladder, or testicular tumors. Of the 68 patients with negative screening chest roentgenograms, all but 2 had negative tomograms. One of these 2 patients had a normal chest film (the other had extrapulmonary metastasis), and he did not have the renal carcinoma initially suspected. Tomography discovered no metastases from urologic malignancy that was not already known about from the screening x-ray film. In 20 cases with a positive screening x-ray film, tomography was of limited value. It cleared two suspicious chest films and added information on extent of metastatic involvement in three. We conclude that whole-lung tomography adds little information not available by chest roentgenogram in our selected population, and with a negative screening chest film no additional chest study is needed.
全肺断层扫描在泌尿生殖系统恶性肿瘤中的作用尚未确定。我们回顾了88例已知或疑似泌尿生殖系统恶性肿瘤且进行了断层扫描的病例。大多数患者患有肾、膀胱或睾丸肿瘤。在68例胸部X线筛查阴性的患者中，除2例之外其余所有患者的断层扫描结果均为阴性。这2例患者中的1例胸部X线片正常（另1例有肺外转移），且他最初怀疑的肾癌并不存在。断层扫描未发现泌尿生殖系统恶性肿瘤有筛查X线片未显示的转移灶。在20例胸部X线筛查阳性的病例中，断层扫描的价值有限。它使两张可疑的胸部X线片结果明确，并为另外3例提供了转移累及范围的信息。我们得出结论，在我们选定的人群中，全肺断层扫描提供的额外信息很少，胸部X线筛查阴性时无需进一步的胸部检查。
