Abstract

The impact of renal artery stenosis (RAS) and resulting ischemic nephropathy on kidney function has been well described. Based on several recent randomized, multicenter trials that revealed limitations to the utility of nonselective renal artery intervention, the general nephrology community has recently taken a conservative stance on this disease state. The purpose of this report is to summarize some recent contributions to our understanding of renal artery stenosis, which may cast RAS intervention in a new light.
