Predictive value of duplex ultrasound for restenosis after renal artery stenting.

Purpose: Factors predicting renal function and recurrent stenosis following percutaneous renal revascularization are poorly identified. The predictive value of hemodynamic duplex ultrasound (DUS) parameters was evaluated.

Methods: In a prospective observational study patients undergoing stenting of renal artery stenosis (RAS) were included.
