A rare consequence of blunt abdominal trauma: bilateral renal infarction.

A 28-year-old man was admitted to the emergency department with lumbar pain owing to a motorbike accident. On clinical examination, abdominal tenderness, pelvic and left cruris pains were present. Erythrocytes, leucocytes and protein was found to be positive in urine analysis. Abdominal computed tomography with intravenous contrast solution showed contrast enhancement in 80% of right kidney, and 30% of left kidney; some intra-abdominal free fluid was also seen. Conservative management was planned for bilateral renal infarction. Urine output was 1.1 L per day. He was discharged on the seventh day of the hospital stay. The patient had not got any problems on the sixth month follow-up. Urine output is a very important parameter for multiple trauma patients. Any decrease in urine output may not be seen inspite of the presence of bilateral renal damage as in the case of the patient, and this situation does not allow ruling out renal injury completely. Hence, emergency physician should still be careful about the risk of renal injury.
