Background: Atherosclerotic renal artery stenosis (RAS) is a significant cause of renal failure, especially in patients with a solitary functioning kidney. Timely revascularization can potentially reverse ischemic nephropathy and prevent further complications like pulmonary edema and uncontrolled hypertension.
Case Presentation: A 71-year-old male with a solitary functioning kidney presented with worsening renal function, chronic hyponatremia, and recurrent flash pulmonary edema. The patient presented with a 95% ostial stenosis of the right renal artery. Percutaneous renal artery stenting was performed successfully, resulting in improved clinical status and renal function. Serum creatinine decreased from 3.07 mg/dL to 2.1 mg/dL post-procedure. The patient remained stable at a two-month follow-up.
Conclusion: Renal artery stenting in patients with ischemic nephropathy secondary to RAS can significantly improve renal function and overall clinical outcomes. Early intervention should be considered in similar cases to prevent irreversible renal damage.
