Renal pseudoaneurysm following laser lithotripsy: endovascular treatment of a rare complication

Abstract

Hemorrhagic complications of renal transplantation can be life threatening and require prompt and timely intervention. This brief report describes the exceedingly rare formation of an extrarenal pseudoaneurysm of a transplant renal artery following laser lithotripsy for nephrolithiasis in a teenage male. The pseudoaneurysm ruptured into the renal collecting system. Transarterial coil embolization of the wide-neck saccular pseudoaneurysm of the extraparenchymal renal artery with the assistance of a 'safety microguidewire' was successfully performed and the allograft was preserved.
