Digital subtraction angiography was compared to computerized tomography and histopathological findings for staging renal cell carcinoma in 24 patients. Injection of contrast material through a 16 gauge angiocatheter into the femoral vein provided digital subtraction cavography, digital subtraction arteriography and excretory urography during 1 investigation. Computerized tomography established the diagnosis in all patients, while digital subtraction angiography showed all angiographic signs of renal cell carcinoma in 14 (58 per cent). T staging was correct on computerized tomography in 18 patients and on digital subtraction angiography in 16. Absence or presence of venous involvement was indicated correctly by computerized tomography in 20 patients and by digital subtraction angiography in 21. In small tumors the combination of ultrasonography, digital subtraction angiography and excretory urography is sufficient for an operation. In all other tumors digital subtraction angiography cannot replace computerized tomography but adds useful information about arterial distribution, possible venous tumor thrombus and the anatomical relationship of vessels.
对24例肾细胞癌患者，将数字减影血管造影与计算机断层扫描及组织病理学检查结果进行比较，以对肾细胞癌进行分期。在一次检查中，通过16号血管造影导管经股静脉注入造影剂，可进行数字减影腔静脉造影、数字减影动脉造影和排泄性尿路造影。计算机断层扫描确诊了所有患者，而数字减影血管造影显示14例（58%）患者出现肾细胞癌的所有血管造影征象。18例患者的计算机断层扫描T分期正确，16例患者的数字减影血管造影T分期正确。20例患者的计算机断层扫描和21例患者的数字减影血管造影正确显示了有无静脉受累情况。对于小肿瘤，超声检查、数字减影血管造影和排泄性尿路造影相结合足以进行手术。对于所有其他肿瘤，数字减影血管造影不能替代计算机断层扫描，但可提供有关动脉分布、可能的静脉肿瘤血栓及血管解剖关系的有用信息。
