Causes
- Lack of oxygen to kidney tissues from problems such as surgical complications or hemorrhage (heavy bleeding)
- Exposure to toxic materials such as antibiotics, x-ray dyes, or anesthetics
Risk Factors
- Injury
- Trauma
- Surgery
- Blood transfusion
- Septic shock
- Shock
- Low blood pressure
- Liver disease or damage
- Drugs (aminoglycosides, amphotericin B, cyclosporine, tacrolimus)
- X-ray dye
-
Toxic chemicals:
- Crystals (uric acid, calcium phosphate)
- Myoglobin
- Hemaglobin
Symptoms
- Change in urine output
- Dehydration
Diagnosis
-
Blood tests
- BUN
- creatinine
- electrolytes
- calcium
- magnesium
- phosphorus
- complete blood counts
- Urine tests (urinalysis, urine sodium, urea, osmolarity)
- Kidney biopsy
- Your doctor may need detailed pictures of your kidney. These can be made with:
Treatment
Dialysis
Medications
Prevention
- 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.
- Take certain drugs when using medications such as aminoglycosides or cisplatin, which are associated with kidney damage.
- Use calcium channel blockers after having a kidney transplant .
