Abstract: 【Abstract】Objective The renal benefit of renal arterial interventional therapy in hemodialysis patients with renal artery stenosis remains unclear. The purpose of this study was to investigate the effect of renal artery interventional therapy on renal prognosis in hemodialysis patients with renal artery stenosis. Methods The clinical data of 19 hemodialysis patients with renal artery stenosis admitted to the Renal Division, Peking University First Hospital from February 1993 to January 2021 were retrospectively analyzed. The primary endpoints were postoperative dialysis discontinuation, death, or kidney transplantation. The secondary endpoints
were blood pressure control before and after intervention, renal artery restenosis, or rEentry to dialysis. Results Ten of the 19 patients (53%) discontinued dialysis after interventional therapy. Serum creatinine (P＜0.001), estimated glomerular filtration rate (P=0.095), length of renal diameter (P=0.012) and maintenance time of dialysis before interventional therapy (P=0.065) were the factors for the efficacy of interventional therapy. No serious complications occurred in any of the patients. Conclusion For hemodialysis patients with renal artery stenosis, renal artery interventional therapy may help patients free from dialysis. This is especially true for patients with low serum creatinine value preoperatively, incomplete renal atrophy, and shorter maintenance time of dialysis before intervention.
