Other tests to diagnose renal failure can include, an ultrasound to reveal any obstruction to the kidneys, an imaging test which include CT scans or MRI to reveal a more detailed image of the kidneys and other organs, a kidney biopsy where a small piece of tissue can be removed and examined, or an x-ray to examine for pulmonary edema, fluid retention in the lungs.
