Diagnostic Accuracy of Ultrasonography for Prediction of Outcome of Renal Artery Stenosis Therapy taking Angiography as Gold Standard

Background: Renal artery stenosis (RAS) is caused by a vast variety of pathophysiologic factors. Amongst various causes fibromuscular dysplasia and atherosclerotic RAS are the most common. A reduction in the diameter of the renal arteries results in development of hypertension, renal dysfunction and/or pulmonary edema. Majority of the cases of RAS remain asymptomatic. Aim: To assess the diagnostic accuracy of ultrasonography for prediction of outcome of renal artery stenosis therapy taking creatinine clearance as gold standard Methods: This cross sectional study was conducted in the Department of Radiology, Shaikh Zayed Hospital, Lahore during a period of six months from 22-03-2017 to 19-09-2017 Results: The mean age of patients was 51.47 +/- 17.69years. The sensitivity, specificity and diagnostic accuracy of USG RI was 93.81%, 91.15% & 92.38% respectively taking renal angiography as gold standard. Conclusion: Ultrasonography for prediction of outcome of RAS therapy is useful and reliable diagnostic tool.
