Renovascular disease in older patients beginning renal
(Jul) 48:171-176 1995
Renal duplex sonography was used to identify renal artery
stenosis (RAS) in 90 consecutive patients beginning dialysis (only half
were completely evaluated for RAS). Ten of 45 patients had critical RAS
(40% of white patients had critical RAS). Importantly, 11% of patients
had bilateral disease, treatment of which could potentially improve
renal function and obviate the need for dialysis. In centers with
expertise in renal duplex ultrasonography, this is a useful noninvasive
test to evaluate at-risk patients for the presence of ischemic
nephropathy. Interestingly, the United States Renal Data System does
not even have a category for renovascular disease as a cause of ESRD.
