Renal parenchymal injuries secondary to blunt abdominal trauma in childhood: a 10-year review.

Sixty-six cases of renal parenchymal injuries secondary to blunt abdominal trauma in childhood are reviewed. Based on radiological findings, the injuries were classified into renal contusions, lacerations and transections. The clinical features were more acute in patients with renal laceration and transection. Complications were more common in patients with renal transection and led to partial or total renal loss in a significant number of cases. Renal contusions and most lacerations should be managed non-operatively but renal transections should in general be managed operatively.
