Background: Percutaneous renal artery embolization is a valid non-invasive technique alternative to nephrectomy for patients with symptomatic non-functioning allograft (graft intolerance syndrome—GIS). The purpose of this article is to report the experience of our centre. Methods: We analysed retrospectively 15 patients with symptomatic non-functioning renal allograft treated with percutaneous embolization from 2003 to 2017. Occlusion was obtained with the injection of calibrated microspheres of increasing size (from 100 to 900 μm) and completed with 5 to 8 mm metal coils placement in the renal artery. Results: Technical success was achieved in all cases at the end of the procedure. Clinical success was obtained in 11 patients (73%). In four cases, nephrectomy was necessary: in one case because of septic fever and in three cases because of GIS persistence. In one case, it was possible to perform another procedure to embolize a perirenal collateral from a lumbar artery. Four patients (27%) reported minor complications which spontaneously resolved during the hospital stay. Conclusions: According to the scientific literature, we believe that, in selected patients, percutaneous renal artery embolization is a valid treatment option for GIS thanks to its efficacy, repeatability, minimal invasiveness and the absence of severe complications.
