A bruised kidney forms after sustaining a direct impact on the lower back region. This injury typically occurs from vehicular accidents, but also from a fall or assault such as being kicked in the back.
The kidneys are a pair of structures positioned in the back part of the abdomen with the size of a closed hand. The main function of the kidneys is to filter out the blood. The blood in the body moves via the kidneys several times in a day. The kidneys eliminate wastes, control the balance of fluid and produce urine that drains down into the bladder. An external injury in the area where the kidneys are located can result to a bruised kidney.
Indications of a bruised kidney
- Immediate pain or discomfort
- Nausea and/or vomiting
- Pain in the lower region of the back, usually on one side
- Muscle spasms in the back muscles
- Blood-streaked urine
Once an individual is suspected with a bruised kidney, it is important to seek immediate medical care.
When a doctor is consulted, the individual is assessed by the doctor and an X-ray is requested to check for any associated injuries such as a rib fracture. The other tests that might be requested include CT scan and MRI to check for internal bleeding.
When it comes to a simple case of a bruised kidney, the individual is monitored closely for a few days. Remember that this injury eventually heals without resulting to further complications within 1-2 weeks.
