BACKGROUND: Delayed diagnosis of concurrent bladder damage in a patient with blunt urethral trauma can lead to a high rate of morbidity. In patients with a high index of suspicion, genitourinary workup is recommended. In complicated patients with multi-trauma, this workup has a risk of being delayed. A proven prognostic indicator to evaluate the likelihood of bladder injury in this population has not been established. The aim of this study was to determine if there was a clinical association between the Injury Severity Score (ISS) and bladder injury involvement among these patients.
METHODS: Retrospective analysis was performed on a cohort of 98 patients who presented with blunt urethral trauma to R. Adams Cowley Shock Trauma Center between 2002 and 2014. Univariate analysis was performed to determine if there was an association between concurrent bladder injuries and ISS among other factors. A receiver operating characteristic curve plot was performed to analyze the association between ISS and bladder involvement.
RESULTS: Of the 98 patients with blunt urethral trauma, 28 had concurrent bladder injury. ISS was shown to have a significant correlation with concurrent bladder injury (OR = 2.2 per 10 unit change in ISS, p = 0.0001). ROC curve analysis showed an area under the curve for the prediction of bladder injury. Patients with ISS ≥ 34 had a 54% chance of bladder injury, while patients with ISS < 34 had a 13% chance.
CONCLUSION: ISS ≥ 34, a score in the range of severe multi-trauma, may be a clinical indicator of bladder injury in patients presenting with blunt urethral trauma.
