Short-Term Renal Function Outcomes after Renal Artery Stenting in Atherosclerotic Renal Artery Stenosis

Abstract

Objectives: Renal artery stenosis (RAS) poses significant challenges due to decreased renal perfusion, leading to various disease processes. We aimed to evaluate the safety and effectiveness of renal artery stenting in patients with atherosclerotic RAS, focusing on early renal function changes and identifying factors influencing treatment response. Materials and Methods: This single-center, retrospective, observational study included patients undergoing renal artery stenting for atherosclerotic RAS over a 10-year period. Clinical and procedural data were analyzed, and renal function outcomes were assessed at the 1-month follow-up. Statistical analysis was performed to identify correlations between patient characteristics, procedural factors, and treatment outcomes. Results: Forty-nine patients were included, with a mean age of 67.08±8.73 years. Successful stenting was achieved in all patients, with no major adverse clinical events reported. At the 1-month follow-up, 67.3% of patients had stable renal function, while 12.2% showed improvement and 20.4% experienced worsening. A significant correlation was found between age and treatment response (p=0.045). However, no significant associations were observed between changes in renal function and other patient characteristics or procedural factors. Conclusion: Renal artery stenting in patients with atherosclerotic RAS resulted in successful procedural outcomes with minimal complications. While age was identified as a significant predictor of treatment response, no other patient or procedural factors showed significant correlations with changes in renal function. Our findings emphasize the need for further research to refine patient selection criteria in this population.
