title: Advances in noninvasive methods for functional evaluation of renovascular disease.
abstract: As the number of patients with newly diagnosed renal artery stenosis increases, so has the number of percutaneous transluminal renal-artery angioplasties in the last few years. Deciding the preferred treatment in the clinical setting is fraught with difficulties related to many factors, and there is limited evidence to support angioplasty/stent for any indication. These considerations emphasize the urgent need for improved noninvasive assessment of kidney function in patients with vascular disease. This review will attempt to summarize the available techniques that may potentially be used for measurement of renal function in this context.
