Blunt injury accounts for 80–95% of renal injury trauma in the United States. The majority of blunt renal injuries are low grade and 80–85% of these injuries can be managed conservatively. However, there is a debate on the management of patients with high-grade renal injury. We reviewed our experience of renal trauma at our trauma center to assess management strategy for high-grade blunt renal injury.


We reviewed blunt renal injury cases admitted at a single trauma center between August 2007 and December 2015. Computed tomography (CT) scan was used to diagnose renal injuries and high–grade (according to the American Association for the Surgery of Trauma [AAST] organ injury scale III-V) renal injury patients were included in the analysis.


During the eight–year study period, there were 62 AAST grade III-V patients. 5 cases underwent nephrectomy and 57 underwent non-operative management (NOM). There was no difference in outcome between the operative group and the NOM group. In the NOM group, 24 cases underwent angioembolization with a 91% success rate. The Incidence of urological complications correlated with increasing grade.


Conservative management of high-grade blunt renal injury was considered preferable to operative management, with an increased renal salvage rate. However, high-grade injuries have higher complication rates, and therefore, close observation is recommended after conservative management.
