Abstract Purpose—To identify the risk factors for progression to renal replacement therapy (RRT) and all-cause mortality in patients who underwent renal artery (RA) stent placement for atherosclerotic renal artery stenosis (RAS).

Materials and Methods—A retrospective study was performed from June 1996 to June 2009 that identified 1052 patients that underwent RA stent placement. The glomerular filtration rate at the time of RA stent placement was estimated from the serum creatinine level and divided into renal disease stages 1–5. Univariate and multivariable Cox proportional hazards models were used to determine which factors were associated with each endpoint. Results—The times to progression to all-cause mortality and RRT were similar for chronic kidney (CKD) stages 1/2/3A and served as the reference group. In multivariable analysis, highgrade proteinuria (P
