1 The ASTRAL (Angioplasty and Stent for Renal Artery Lesions) trial4 is a multicentre study in the United Kingdom involving 1000 patients with atherosclerotic RArtS, including many with diabetes. This is the largest interventional trial in atherosclerotic

RArtS and is designed to address the issue of whether renal artery revascularization with balloon angioplasty and/or endovascular stenting can safely prevent progressive renal failure among patients with RArtS. Results of the trial should be available in 2006 and will hopefully dictate appropriate treatment options for patients with significant RArtS.
