Acute kidney injury (AKI)

What is it?   

 

The kidneys are located under the ribcage, on either side of the spine. They are the urinary tract organs that get injured most often.

The kidneys are protected by the spine, the back muscles, and the lower ribcage, as well as a cushion of fat.

A kidney injury may affect part of the kidney and severity may vary. There can be many causes for a kidney injury - some are listed below.

 

 

Prognosis

 

Prognosis will depend on the cause and the seriousness of the injury. The injury may be mild and reversible, but it some cases it could be lethal. They can also go on to cause long-term problems, which could end up causing a variety of complications.   

There are some cases where the kidney starts to function properly again, and others where there is kidney failure.   

If injuries are detected early, patients tend to make a full recovery.    

 

What are the symptoms?

 

Kidney injury symptoms may include pain or bruising above the abdomen or between the hip and ribs. Other common symptoms include:

  • Blood in the urine or an inability to urinate
  • Abdominal, back, or side swelling or pain
  • Drowsiness
  • Increased heart rate
  • Vomiting or nausea
  • Pale or cold skin
  • Sweating

It should be noted that if one kidney is injured and the other is healthy, symptoms may not be present.
