ABSTRACT：ObjectiveTo explore the independent risk factors for long-term adverse prognosis after percutaneous renal artery angioplasty in patients with transplant renal artery stenosis（TRAs）.MethodsWe retrospectively collcted medical records and surgery details of TRAS patients who underwent renal artery angioplasty at the Department of Peripheral Vascular Diseases，The First Affiliated Hospital of Xi'an Jiaotong University，from January 2O17 to June 2021.All patients were followed up for 3years post-operation.Multivariate Cox regresson analyses were performed to find the independent predictive factors for long-term adverse prognosis after renal artery angioplasty in the TRAS patients. ResultsA total of 45 TRAS patients who underwent percutaneous renal arteryangioplasty were included in this study.During the five-year follow-up period，1O patients （22.2% ） experienced long-term adverse events. These consisted of 3 patients （6.7% ） who died from any cause， 1 patient （2.2% ）who developed transplant renal artery dissection，6 patients （13.3%） ）who had restenosis of the transplant renal artery，andlpatient （2.2% ）who lost the transplantkidney and received dialysisagain.Multivariate Cox regression analysis showed that male gender（ HR=4.915 ， 95% （20 CI 1.036-23.328 ， P=0.045 ）and balloon angioplasty alone （ HR=8.594 95% （204 CI ：2.191—33.710， P=0.002 ）were independent risk factors for long-term adverse prognosis after renal artery angioplasty in TRAS patients.ConclusionMale gender and baloon angioplasty alone are independent risk factors for long-termadverse prognosis afterrenal artery angioplastyin TRAS patients
