title: Renal trauma in adolescent skateboarders.
abstract: OBJECTIVE
  Kidney is the most commonly injured organ of the genitourinary tract after trauma. Half of blunt renal injuries are caused by traffic accidents, but sport activities are also included as frequent causes. Skatebording is popular among young people but it deserves being considered a potential cause of severe injuries. A number of published medical reports mainly refer to bone, joint and head injuries but no cases have been reported on urologic or kidney trauma.
  
  
  METHODS
  We present two cases of renal trauma in adolescent males occurred while doing skateboarding.
  
  
  RESULTS
  The first patient had a grade 3 renal trauma with urinary extravasation, managed conservatively with ureteral stenting. The second patient had a grade 4 to 5 renal trauma with cardiovascular instability requiring an urgent nephrectomy.
  
  
  CONCLUSIONS
  We would emphasize these cases as an emergent urological warning. Scientific information and medical education should be addressed from physicians to a targeted population, in order to reduce among teens the incidence of injuries of such at-risk activity.
