Abstract:
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 ?g) 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.
