BackgroundBackground If injury to GU system identified, multi-If injury to GU system identified, multi-
organ injury is the rule.organ injury is the rule. Examples:Examples:
– If renal injury found following penetrating If renal injury found following penetrating trauma, 80-95% chance of other significant trauma, 80-95% chance of other significant injuryinjury
– If renal injury found following blunt trauma, 75% If renal injury found following blunt trauma, 75% chance of other significant injury foundchance of other significant injury found
Other injuries may be more immediately life Other injuries may be more immediately life threatening and thereforethreatening and therefore
GU injury diagnosis may be overlooked or GU injury diagnosis may be overlooked or delayeddelayed
