Comparative Study
Use of ultrasonography in the patient with acute renal trauma.
The purpose of this study was to assess the use of emergent ultrasonographic examination in acute traumatic renal injuries. Over a 3 year period, prospective data of all patients who had an emergency ultrasonogram were recorded. Thirty-two patients with 37 renal injuries were studied retrospectively to identify in how many patients the sonogram detected free fluid or a renal parenchymal abnormality. ⋯ Furthermore, the ultrasonogram of the kidney often is normal with acute renal injuries, but it is more likely to be abnormal with severe (grade II or greater) renal injuries. Sonography may be used in the triage of patients with blunt abdominal trauma and possible renal injury. However, a negative ultrasonogram does not exclude renal injury, and, depending on clinical and laboratory findings, other imaging procedures such as computed tomography should be performed.
