Kidney Laceration

A kidney laceration (or rupture) occurs following a blunt impact to the lower back region. The extent of the injury can vary considerably.

Symptoms of Kidney Laceration

  • Symptoms can vary and mild damage may initially show no symptoms.
  • Usually the abdomen will be painful on palpation.
  • Blood in the urine.
  • Nausea or vomiting.
  • Changes in blood pressure and pulse.
  • Shock which may lead to unconsciousness.


  • Impacts to the abdomen, especially the lower back area.
  • Falls, car accidents and physical attacks are the most common causes.


To confirm the diagnosis of a kidney laceration and the extent of the damage a patient may under go:

  • A CT scan to view the kidneys.
  • An Aortogram. This is where a special dye is injected into the main artiery (the aorta). X-rays are then taken of the area as the blood containing the dye travels through the kidneys. A leak can be seen clearly here.


  • Treatment depends on the extent of the damage.
  • Minor lacerations may only require observation to check that the kidney is still functioning efficiently.
  • In more serious cases, surgery may be required.
  • The aim of surgery is to stop bleeding and to preserve the kidney tissues and function.
