  • INTRODUCTION Evidence suggests overutilization of procedural intervention for renal traumas. The objective of this study was to assess clinical factors associated with procedural intervention for patients presenting to the emergency department (ED) with isolated renal trauma.


    A United States statewide trauma registry was queried for trauma patients presenting to level I or II trauma centers with isolated renal injuries (Grades I–V) from 2000-2013. Patient demographics, mechanism, American Association for the Surgery of Trauma (AAST) grade, trauma center level designation, presenting ED vital signs, Glasgow Coma Scale (GCS), intubation status, and blood product transfusion were assessed.


    Of 449,422 patients, 1383 patients (78% male, median age 29 years [range 2-92]) with isolated renal injuries had data available for analysis. Controlling for demographics, presenting vitals, GCS, trauma center level, mechanism and intubation status, level I status (OR 2.1 [1.3-3.4], p = 0.0021), white race (OR 2.5 [1.3-4.7], p < 0.005), AAST IV/V injury (OR 4.79 [3.1-6.5], p < 0.0001) and blood product administration (OR 2.7 [1.5-4.9], p = 0.0009) were independently associated with an immediate interventional radiology procedure. Independent predictors of immediate surgical intervention include level I status (OR 2.2 [1.2-4.0], p = 0.0075), penetrating mechanism of injury (OR 15.6 [8.4-28.9], p < 0.0001, AAST IV/V injury (OR 13.6 [8.7-21.1], p < 0.0001), and clinical hypotension (SBP < 95 mmHg, OR 2.1 [1.1 4.2], p = 0.03).


    Level 1 trauma center designation, white race, penetrating mechanism of injury, high-grade injury, transfusion of blood products, and hypotension were all independent predictors of immediate procedural intervention following ED presentation with isolated renal trauma
