Answer

Use of renal artery revascularization has been declining in recent years, mainly because trials to date have failed to demonstrate major advantages from the procedure. However, in a 2013 review, Textor et al note that trials of revascularization “have been small, conducted over short intervals, and have been ferociously criticized on methodologic grounds”. [53] These authors observe that endovascular repair is most likely to succeed when it is performed in patients with a recent deterioration in kidney function, which argues for careful identification and selection of patients for revascularization before loss of GFR becomes far advanced.
