title: [Functional damages after blunt renal trauma in children].
abstract: OBJECTIVE
  The purpose of this study was to determine the long-term functional outcome of renal injuries.
  
  
  METHODS
  We retrospectively reviewed the charts of patients under 16 sustaining renal trauma and admitted to our department between 1990 et 2010. There were 66 renal lesions categorized as follows: grade I to III, 33, grade IV, 28 and grade V, 5. Whatever their initial status, all children were followed using ultrasonography or computed tomography. After complete healing, data of technetium-99m-dimercaptosuccinic acid nuclear were collected.
  
  
  RESULTS
  There was no bilateral injury. Thirteen patients proceeded to laparotomy leading to nephrectomy in three cases, partial nephrectomy in two others cases. Four renovascular injuries required interventional radiologic management. Nine urinomas were managed with eight stentings and one percutaneous drainage. Percentage of renal function by technetium-99m-dimercaptosuccinic acid nuclear scanning concerning 26 patients was analysed. Split percentage of renal function was 43.4% (±6.2%), 35.7% (±5.3%) et 30.3% (±12.2%) (mean±SD); P=no significant, for grade I-III, IV and V, respectively.
  
  
  CONCLUSIONS
  Functional outcome after blunt renal trauma appeared influenced by injury grade. Functional sequelae existed even with low-grade traumas. In keeping with literature, these results justified a close follow-up in which radionuclide study was the essential element.
