Stent\-assisted renal artery angioplasty is a highly effective and mostly safe method of RAS management, with technical success 99.2% and incidence of serious periprocedural complications 2.84%, including in\-hospital mortality 0.47%. This is despite the high\-risk patient profile including documented significant CAD \(69.2%\), multilevel atherosclerosis \(47.4%\) and renal dysfunction \(eGFR <60 ml \/ min \/ 1.73 m2 in 61.6%\). 2. Successful PTA is associated with a significant reduction in systolic \(12 mmHg on average\) and diastolic \(5 mmHg on average\) blood pressure and an improvement in renal function \(average eGFR increase by 4 ml \/ min \/ 1.73 m2\). 3. Renal function improvement \(defined as eGFR increase > 11 ml \/ min \/ 1.73 m2\) predictors are baseline kidney dysfunction \(creatinine concentration > 117 μmol \/ L\) but with an eGFR value exceeding 30 ml \/ min \/ 1.73 m2, low resistive index both in the renal artery and intra\-renaly \(RI <0.77 and IRI <0.68\), as well as index kidney length > 98 mm\; while history of poor blood pressure control with documented multidrug regimen of at least 4 antihypertensive drugs reduces the chances of eGFR improvement. 4. Blood pressure reduction predictors are high blood pressure values prior to revascularization \(> 145 mm Hg for s"]
