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