title: Interventional radiology in the treatment of retroperitoneal trauma.
abstract: Interventional radiology is used most often in the management of the trauma patient to control hemorrhage and drain fluid collections. Transcatheter arterial embolization is an effective, expeditious, and safe technique for the nonoperative control of renal and other retroperitoneal bleeding, arteriovenous fistulas, and pseudoaneurysms. Transcatheter drainage of renal and other retroperitoneal collections of pus, urine, and blood is successful in more than 90% of trauma patients; such drainage should be attempted prior to any surgical intervention. Other procedures, such as antegrade nephrostomy, ureteral stenting and dilatation, angioplasty of traumatic renal artery stenosis, and suprapubic cystostomy, are infrequently indicated but provide alternatives to standard surgical intervention.
