Endovascular management of severe renal trauma: a therapeutic challenge

Severe renal trauma is a rare and potentially life-threatening condition that requires rapid and individualized management. Selective embolization has proven to be an effective and minimally invasive option for hemorrhage control and renal function preservation. We present two cases of severe renal trauma, one blunt and one penetrating, successfully treated with superselective embolization. In the first case, microcoils were used for segmental branch occlusion; in the second, cyanoacrylate glue (Hystoacryl + Lipiodol, 33%) was applied. Both patients achieved hemodynamic stabilization, laboratory recovery, and preserved renal function without complications. Endovascular management proved to be a safe and decisive treatment, avoiding nephrectomy and reinforcing the essential role of interventional radiology in the management of high-complexity renal trauma.
