What Causes Kidney (Renal) Trauma?

Kidney trauma can occur as kidney injury alone or with other damaged organs. The kidney is the urinary tract organ most often injured by severe trauma.

Blunt trauma can be caused by

  • Car accident (children are especially vulnerable to injury in car accidents)
  • Fall
  • Being hit hard by a heavy object, especially in the flanks (between the rib and the hip)
  • An action where the body comes to a sudden stop after moving quickly

Penetrating trauma can be caused by

  • Bullet
  • Knife
  • Any object piercing the body

Kidney injury is rated on a five-grade scale based on how bad it is. Grade one refers to minor injury, such as bruising. Grade five is the most severe, where the kidney is shattered and cut off from its blood supply.
