Instituting a conservative management protocol for pediatric blunt renal trauma: evaluation of a prospectively maintained patient registry.

PURPOSE: Retrospective studies show that even high grade pediatric renal trauma can be safely managed conservatively. We evaluated a prospective patient registry at our level 1 pediatric trauma center, where patients with renal trauma were treated with an institutional review board approved conservative blunt renal trauma protocol. Standardized treatment included a trial of expectant management for all stable cases.
MATERIALS AND METHODS: We identified 39 children with blunt renal trauma treated between 2003 and 2008. A strict conservative approach was used, ie nonoperative management in cases that were hemodynamically stable or had a favorable response with up to 2 units of blood transfused and no operative renal lesion on imaging. Adult imaging protocols were followed and exploratory laparotomy for nonrenal causes did not alter course of expectant renal management. Outcomes evaluated were injury grade, hematuria, operative management, length of stay and associated injuries.
RESULTS: Based on the American Association for the Surgery of Trauma organ injury severity scale, 13 patients were considered to have grade I disease, 8 grade II, 11 grade III, 6 grade IV and 1 grade V. Conservative management resulted in a 97% nonoperative rate and a single renorrhaphy.
CONCLUSIONS: Using a prospective patient registry, this study demonstrates that conservative treatment of blunt pediatric renal trauma is safe and effective. Also, serious renal injuries are not missed by applying adult diagnostic imaging protocols in children.
