Traumatic avulsion of the ureter: computed tomography correlation.

Avulsion of the ureter is a rare but significant traumatic injury, and there is often a delay in diagnosis and treatment. Radiologic signs have been described for intravenous urography but are not always present. To our knowledge, the computed tomographic appearance of avulsion of the ureter has not been described. Herein, we report the contrast-enhanced computed tomography findings in a case of traumatic avulsion of the ureter.
