Massive perirenal and intra-abdominal bleeding after shock-wave lithotripsy: case report.

Complications of extracorporeal shock-wave lithotripsy are rare, with an incidence of symptomatic perinephric hematoma ranging from 0.2% to 0.66%. A 59-year-old man had massive symptomatic retroperitoneal and intra-abdominal bleeding 24 hours after lithotripsy. The hemorrhage was managed successfully by conservative measures, which consisted of packed red blood cells and fresh frozen plasma. The literature on the bleeding complications of lithotripsy is reviewed and the risk factors are identified.
