title: [Outcome of severe closed kidney injuries in children].
abstract: OBJECTIVE
  To analyze the results of treatment of major renal injuries according imaging data in order to determine their function after follow-up.
  
  
  METHODS
  This is a retrospective study of 22 cases of fracture of the kidney (grade V) in two pediatric surgical services that were reviewed over a period of 16 years. After initial conservative treatment in 19 patients (86.5%), a scan and/or Uro-MRI were realized in all patients in monitoring evolving. Three children with vascular injury were treated by interventional radiology. The morphology and functional evolution of the injured kidney were determined.
  
  
  RESULTS
  A DMSA scan investigation was performed in 21 patients (95.5%) associated with Uro-MRI in two cases; one patient was only explored with Uro-MRI. A complete restitution of the renal parenchyma was confirmed in 10 children (45.5%), we noted an atrophy of the upper pole in 30%, a lower pole atrophy in 4.5%, two complete renal atrophy in 9%. An urinoma was present in six patients (27%) that required drainage in five cases and declined during the surveillance in one case. Normal function of the injured kidney was noticed in half of grade V (11 of 22 patients) with a mean follow-up of 19 months. None of our patients did present hypertension.
  
  
  CONCLUSIONS
  Non-operative conservative treatment in severe renal trauma was efficient, morphological and functional sequelae were present in 50% on scintigraphy and/or Uro-MRI.
