title: Refractory hypertension with massive proteinuria may be reversed in renal artery stenosis patients with low proteinuria selectivity index after stenting.
abstract: BACKGROUND
  No available prognostic factor was identified for atherosclerotic renovascular stenosis (ARAS) patient who undergo the percutaneous revascularization therapy.
  
  
  METHODS
  This is a case of 68-year-old ARAS patient associated with hypertension and massive proteinuria, who exhibited progressive aggravation of renal dysfunction. His proteinuria selectivity index (SI) was only 0.08. Then the stenosis was treated by percutaneous transluminal angioplasty of the renal artery (PTRA) and stenting. After 2-year follow up, all symptoms including renal dysfunction and uncontrolled hypertension was well-controlled.
  
  
  CONCLUSIONS
  As no reliable predictors of clinical response have been identified yet, SI might be a simple prognositic index for ARAS patients undergone the revascularzation therapy.
