Diagnosis Method for Renal Failure

Renal failure, or kidney failure, can be acute or chronic. Acute renal failure is a sudden inability of kidneys to remove waste and concentrate urine. Chronic renal failure is a slow loss of kidney function. A variety of tests are used to diagnose renal failure.

  1. Ultrasound

    • Ultrasound tests are commonly used to diagnose renal failure. The test uses sound waves and computers to generate images of your kidneys. These images can reveal any obstructions causing problems.

    Imaging Tests

    • CT scans and MRI are also used to diagnose renal failure. These tests give doctors a more detailed image of your kidneys and other internal organs.

    Kidney Biopsy

    • A small piece of your kidney tissue may be removed and examined under a microscope to better diagnose renal failure.

    X-ray

    • For chronic renal failure a chest x-ray can be helpful in diagnosis. The x-ray is to check pulmonary edema, or fluid retention, in your lungs.

    Blood/Urine Tests

    • Diagnosis may include blood and urine tests to check for elevated levels of blood potassium and waste products such as urea and creatinine.
