title: [A case of superselective transcatheter embolization for injured renal segmental artery associated with percutaneous nephroureterolithotomy (PNL)].
abstract: A case in which the renal segmental artery was injured due to percutaneous nephroureterolithotomy (PNL) and treated by superselective transcatheter embolization is reported. The patient was a 30-year-old man with left ureteral and bilateral renal calculi. The left renal and ureteral calculi were successfully removed by PNL and a 24Fr. nephrostomy catheter was placed for 8 days after PNL. A few minutes after removal of the nephrostomy catheter, arterial bleeding, which seemed to occur due to injury of renal segmental artery associated with PNL, began. The bleeding was stopped by replacement of a 24Fr. nephrostomy catheter and the patient received 5 units of packed red blood cells. Six days after hemorrhage, superselective transcatheter embolization was performed. No further bleeding occurred and the nephrostomy catheter was removed 2 days later without any incident. This interventional technique is safe and useful to control bleeding from renal segmental artery injured by PNL.
