title: [Retroperitoneal hematoma in children].
abstract: BACKGROUND
  Retroperitoneal hematoma is frequently due lo blunt trauma and is a challenging problem. Incidence of this complication in adults is high, but in childhood is uncommon.
  
  
  METHODS
  Analysis of 30 cases is presented. PTS was found between 10 and 12 points, zone II, 12, zone III, 17, and zone I, only one. We observed 33 associated injuries: 17 were pelvic fractures and nine, ureteral rupture. Three patients underwent hepatic or splenic laceration. Seventy-three percent of patients had exploratory laparotomy, but did not have exploration of retroperitoneum.
  
  
  CONCLUSIONS
  Retroperitoneal hematoma in infancy should be treated conservatively.
