title: Early migration and ureteric obstruction of an embolisation coil used to treat massive haemorrhage following percutaneous nephrolithotomy.
abstract: 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.
