title: Conservative Management of Major Blunt Renal Trauma with Extravasation: A Viable Option?
abstract: OBJECTIVE
  To evaluate our experience in the management of patients with major blunt renal trauma treated at a major urban trauma center during the last ten years.
  
  
  METHODS
  The medical records of 72 patients with major blunt renal lacerations treated from 1998 to 2008 were reviewed retrospectively. Patients were broken down into two groups based on whether they were managed conservatively (group 1) or surgically (group 2). Each group was compared with respect to the initial evaluation, computerized tomography findings, associated injuries, hospital stay, transfusion requirements, nephrectomy rate, complications and follow-up imaging.
  
  
  RESULTS
  There were 57 patients with grade IV and 15 patients with grade V renal injuries. Of these, 51 (70.8%) patients were managed conservatively (48 with grade IV and 3 with grade V) and 21 (29.2%) patients were managed surgically (9 with grade IV and 12 with grade V). Patients in group 1 had significantly lower transfusion requirements (3.1 vs. 7.5 units, p < 0.0001), shorter hospital stays (11.8 vs. 15.9 days p < 0.003) and fewer complications (21.6 vs. 76.1%, p < 0.001). No death was observed in group 1, while three in group 2 died of major associated injuries. All surviving patients had significant resolution of the extravasation before hospital discharge.
  
  
  CONCLUSIONS
  Our data supports the conservative management of grade IV blunt renal parenchymal injuries in the absence of hemodynamic instability of renal origin. Even select patients with grade V parenchymal injuries can undergo a trial of conservative management.
