[Urologic traumatology in childhood (closed injuries)].

Critical injuries of the kidney have to be treated surgically immediately. Here also have to consider the same rules of the surgery that go with an acute abdomen. By slight and severe injuries to the kidneys there is adaequate time for a thorrow diagnostic work up, prior to eventual operative intervention. The extreme rare ureter lesions with the symptomatic of a peritonism due to an urinoma and a retroperitoneal haematoma have to be treated operatively at the earliest possible time. Injuries to the urine bladder have always to be treated operatively with a special urgency since letality increases rapidly after six hours after the injury. Lesions of the urethra have to be treated operatively early by eliminating haematoma and urine and exact anastomosis of urethra's stumps to avoid later complications through scar-building.
