Early Migration and Ureteric Obstruction of an Embolisation Coil Used to Treat Massive Haemorrhage Following Percutaneous Nephrolithotomy

摘要

Renal artery embolization is the treatment of choice for massive hemorrhage after percutaneous nephrolithotomy. Late coil migration is a known complication after embolization. We report an unusual case of early coil migration causing ureteric obstruction and postulate on risk factors for this phenomenon.
