How Is It Diagnosed?
In order to confirm diagnosis, the physician uses a combination of physical examination, review of medical history, as well as testing. Oftentimes, there are not many symptoms if any until the disease has progressed significantly. Diagnosis is generally confirmed by the following testing in conjunction with sign and symptoms review:
- Diagnostic angiogram (arteriogram):a thin, flexible tube is inserted into the artery and dye is injected under x-ray imaging to note any areas of narrowing, blockage, or aneurysm.
- Duplex ultrasound:can check blood flow and the structure of renal veins and arteries.
- Venography:using a small amount of a radioactive substance, this test can check the structure and function of the kidneys.
- MRA or CTA imaging:either form of imaging utilizes contrast dye to visualize areas of narrowing or blockage in the kidney arteries.
