Renal Artery Stenting Crucial to the Recovery from Acute Worsening of Chronic Renal Failure

: Recent randomized studies have failed to note any benefits to adding renal artery stenting to optimal medical therapy in patients with atherosclerotic renal artery stenosis (ARAS). We herein present the case of a 75-year-old woman with acute worsening of chronic renal failure in whom renal stenting was essential to saving the patient's life and avoiding dialysis. Although the long-term usefulness of renal artery stenting for ARAS remains controversial, this procedure should be kept in mind as a viable option for treating acute critical cases such as this.
