Key result
Modern angioplasty, stenting, and less-invasive diagnostics simplify renovascular hypertension management.
Why the study?
Interest in identifying renal artery stenosis has been stimulated by recognition of its role in progressive ischemic nephropathy alongside advances in less invasive diagnostics and percutaneous renal stenting.

May facilitate renovascular hypertension care; leaves open need for randomized outcome validation.
Renovascular hypertension is the most common cause of secondary hypertension. Interest in identifying patients with renal artery stenosis has been stimulated recently by advances in three areas. First, is the realization that not only can renal artery stenosis cause renovascular hypertension, but it can also lead to progressive renal failure (ischemic nephropathy) caused by progression of disease, usually atherosclerotic in nature. Second, advances in percutaneous transluminal renal angioplasty and, especially, the recent use of renal stents has led to a less invasive management of these patients as compared with traditional renal revascularization. Finally, the development of newer less invasive diagnostic techniques, both for the identification of patients with renal artery stenosis and to follow patients with known renal artery stenosis, has simplified the diagnostic aspect of the disease.

Edwin Darracott Vaughan (1998) conducted a review in Renovascular hypertension and renal artery stenosis. Percutaneous transluminal renal angioplasty and renal stents vs. Traditional renal revascularization was evaluated. Percutaneous transluminal renal angioplasty, renal stents, and newer less invasive diagnostic techniques have simplified the diagnosis and management of renovascular hypertension.
