title: The association between operative repair of bladder injury and improved survival: results from the National Trauma Data Bank.
abstract: OBJECTIVE
  The bladder is the most commonly injured genitourinary organ from blunt pelvic trauma. In this study we describe traumatic bladder injuries in the United States, their management and association with mortality.
  
  
  METHODS
  We queried the 2002 to 2006 National Trauma Data Bank for all subjects with bladder injury. Demographics, mechanism of injury, coexisting injuries, type of bladder injury, and operative interventions for bladder and other abdominal trauma are described. Multivariate logistic regression analysis was used to examine the relationship between bladder injury and in-hospital mortality.
  
  
  RESULTS
  Of 8,565 subjects with bladder trauma 46% had pelvic fracture and 15% had 2 or more intra-abdominal injuries. Of these subjects 54% underwent bladder surgery, including 76% with intraperitoneal injury and 51% with surgical repair of other abdominal organs. On multivariate analysis operative bladder repair reduced the likelihood of in-hospital mortality by 59%. Greater likelihood of death was seen in African-American and Native American patients, and those with pelvic injuries, triage to higher acuity care, penetrating trauma and multiple abdominal injuries.
  
  
  CONCLUSIONS
  We demonstrated that surgical repair provides a significant survival advantage for subjects with bladder trauma. With 76% of intraperitoneal bladder injuries being repaired, there appears to be underuse of a lifesaving procedure. Additional studies to refine indications for bladder repair are warranted.
