The standard pattern of investigation for renal masses usually involves excretion urography, ultrasonography and angiography. This study was undertaken to determine whether computed tomography (CT) and fine needle aspiration cytology could provide information that might allow this pattern to be modified. Diagnostic information was obtained by needle aspiration cytology in 25 patients who were shown at operation to have a neoplasm. The diagnosis was correct in 22 cases (88%). By comparison, arteriography was accurate in 22 out of 24 (92%), and computed tomography provided the correct diagnosis in 19 out of 21 (90%). Staging was performed surgically and histologically in 21 patients, and when this was compared with the results of CT staging there was complete agreement in 13 cases (62%). A literature review revealed an average staging accuracy for CT of 81% while arteriography was accurate in only 57%. Thus CT appears to be as good as arteriography for diagnosis and potentially better for local staging. It is also less invasive, rapid and cost effective and could supersede arteriography as the primary diagnostic and staging investigation in patients with a solid renal mass.
肾肿块的标准检查模式通常包括排泄性尿路造影、超声检查和血管造影。本研究旨在确定计算机断层扫描（CT）和细针穿刺细胞学检查是否能提供可用于修改该模式的信息。对25例经手术证实患有肿瘤的患者进行了针吸细胞学检查以获取诊断信息。22例（88%）诊断正确。相比之下，24例中有22例（92%）动脉造影诊断准确，21例中有19例（90%）计算机断层扫描诊断正确。对21例患者进行了手术和组织学分期，并将其与CT分期结果进行比较，13例（62%）完全一致。文献综述显示CT分期的平均准确率为81%，而动脉造影仅为57%。因此，CT在诊断方面似乎与动脉造影一样好，在局部分期方面可能更好。它还具有侵入性小、速度快和成本效益高的特点，可能会取代动脉造影，成为实性肾肿块患者的主要诊断和分期检查方法。
