摘　　要：目的　评价注射肾上腺素后行肾动脉造影 (药物造影 )对肾脏肿瘤的诊断价值。方法　对 47例有肾脏占位病变的患者肾动脉内注射 6μg肾上腺素后造影的结果与病理结果进行对比分析 ,并计算评价真实性的各项指标。 结果　药物造影判断恶性肾肿瘤的灵敏度 93 % ;特异度 94% ;准确率 94% ;阳性预告值 97% ;阴性预告值 89% ;阳性似然比 15 .8;阴性似然比 0 .0 7;约登指数0 .87。结论　肾上腺素药物造影对肾肿瘤定性诊断有重要价值 。Objective To evaluate diagnostic significance of renal arteriography by injecting adrenalin in patients with renal tumour.Methods The renal angiography after administration of adrenalin (6 μg) in 47 patients with renal malign ant tumour were performed.The angiographic results were analysed in comparison with that of pathology.The diagnostic accuracy parameters including sensitivity,specificity,accuracy,positive prediction rate,negative prediction rate,positive and negative index were caluclated.Results The sensitivity, specificity and accuracy in the detection of renal malign ant tumour were 93% ,94% and 94% respectively. Positive prediction rate were 97%,negative prediction rate was 89%, positive likelihood rate was 15.8, negative likelihood rate was 0.07 and Youden index was 0.87.Conclusion Medicaments angiography by injecting adrenalin is of important diagnostic value for renal tumour,especially for those which are vascularized and could not diagnosed by other technology qualitatively.
