PTRA, percutaneous transluminal renal angioplasty; PTRAS, percutaneous transluminal renal angioplasty with stenting; BP, blood pressure
Clinical success in renal outcome was defined as increase in estimated glomerular filtration rate (eGFR) > 15%. Clinical success in BP reduction was defined as reduction in mean arterial pressure (MAP) > 15% or decrease in antihypertensive medication. Composite outcome was defined as kidney transplant graft failure or transplant renal artery restenosis
A p-value < 0.05 indicates statistical significance
