Abstract

Background: The aim of this study was to assess the effects of percutaneous bilateral renal
artery stenting in patients with atherosclerotic renal artery stenosis and in-hospital and
4 month outcome of the procedure, focusing on the changes in renal function and blood pressure.

Methods: Five consecutive patients (mean age: 64.8 ± 9.7 years, 1 women) with bilateral
renal artery stenoses underwent percutaneous interventions. We compared blood pressure,
number of oral antihypertensive medications, and renal function changes preprocedure and
postprocedure at 4 months follow-up.

Results: A total of 5 bilateral atherosclerotic renal artery stenosis patients underwent
percutaneous transluminal renal angioplasty and 10 stents were placed. Although systolic and
diastolic blood pressures were significantly decreased in follow-up period, glomerular filtration
rates were not significantly changed as compared with baseline data (p = 0.009, p = 0.008,
p = 1.00, respectively). Also, the number of oral antihypertensive medications were significantly
decreased at follow-up period (p = 0.03).

Conclusions: Bilateral renal artery stenting provides a beneficial outcome such as
stabilization of renal functions, significant improvement in blood pressure control and
reduction in the number of oral antihypertensive medications at follow-up.
