Acute tubular necrosis is damage to the tubule cells (tiny tube-shaped cells) in the kidney that results in acute kidney failure. This is a potentially serious condition that requires care from your doctor.

Acute tubular necrosis can be caused by:
Lack of oxygen to kidney tissues from problems such as
, severe dehydration
or hemorrhage (heavy bleeding)
- Exposure to toxic materials such as antibiotics, x-ray dyes, or anesthetics
A risk factor is something that increases your chance for getting a disease or condition. Risk factors that increase your chance of developing acute tubular necrosis include:
(Injury or trauma that damages the muscles)
- Blood transfusion
- Septic shock
- Low blood pressure
- Liver disease or damage
- Drugs (aminoglycosides, amphotericin B, cyclosporine, tacrolimus)
- X-ray dye
Blood transfusion reaction
This list is things produced by the body, maybe we also need to discuss toxic chemicals from elsewhere
- Crystals (uric acid, calcium phosphate)
If you experience any of these symptoms, do not assume it is due to acute tubular necrosis. These symptoms may be caused by other, less serious health conditions. If you experience any one of them, see your physician.
- Change in urine output
General swelling, fluid retention
Your doctor will ask about your symptoms and medical history. A physical exam will be done. Tests may include the following:
- complete blood counts
- Urine tests (urinalysis, urine sodium, urea, osmolarity)
Your doctor may need detailed pictures of your kidney. These can be made with:
Talk with your doctor about the best treatment plan for you. In addition to good nutritional support
treating underlying condition, dietary changes,
treatment options include the following:
Dialysis, in which a machine does the work of your kidneys by purging waste from your body.
Certain medications (eg, furosemide, bumetanide, mannitol, fenoldopam, auriculin anaritide, and synthetic atrial natriuretic peptide) may reduce the need for
in certain people with acute tubular necrosis.
The following measures may help reduce your chances of developing acute tubular necrosis:
Promptly treating conditions that can lead to decreased blood flow as well as decreased oxygen to the kidneys
- Take measures recommended by your doctor to prevent kidney damage caused by the dyes used in x-ray studies such as with the use of oral N-acetylcysteine or theophylline.
Mostly this is accomplished by increasing fluids
Take certain drugs when using medications such as aminoglycosides or cisplatin, which are associated with kidney damage.
Not sure what this means. What I know or was able
to read indicates that using them less often and monitoring levels is how to do this. I don't know that there are drugs that can prevent this. I checked GRU's 1 and 2
Use calcium channel blockers after having a
