Bedside Ultrasound Diagnosis of a Traumatic Bladder Rupture

Abstract

Background Urinary bladder rupture is a complication of both blunt and penetrating trauma. Significant morbidity and mortality can result from a missed rupture and its ensuing complications. Patients who are at risk for traumatic bladder rupture should undergo appropriate testing to expedite the diagnosis. Current diagnostic modalities include computed tomography (CT) cystography, and retrograde cystography. Although these modalities carry a sensitivity and specificity of 95–99% and 95–100%, their utility is limited by the resources and staff available. Furthermore, both techniques require that a potentially hemodynamically unstable trauma patient be transported out of the Emergency Department for the entire duration of the procedure. Objective The following case report reviews the incidence and management of traumatic bladder rupture and describes how emergency physicians (EP) can use ultrasound to make this diagnosis quickly and safely at the bedside. Case Report The case report describes a patient involved in a motor vehicle collision with a history concerning for urinary bladder injury. A bedside ultrasound study performed by the EP was used to establish the diagnosis of urinary bladder rupture. The ultrasound demonstrated a small contracted urinary bladder with copious free fluid anterior to the bladder wall. The diagnosis was confirmed by CT and the patient was taken expeditiously to the operating room. Conclusion This case provides an example of how bedside ultrasound can be used to make an accurate and timely diagnosis of urinary bladder rupture and help expedite patient care.
