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.
