What to Expect Before the Procedure

You’ll likely be asked to fast for a few hours before the test, depending on your doctor’s instructions. Bring any medications you take daily, even if it’s just your morning dose, and inform your doctor about all medications or supplements you’re taking to avoid interactions. You may receive a sedative to help you relax during the procedure.

During the Procedure

A doctor will insert a thin, flexible tube (catheter) into a vein in your arm or groin, guided through your blood vessels to the kidney area. A contrast dye will be injected to make blood vessels visible on X-ray images. You may feel a brief pinch or pressure, but the procedure is generally quick and painless.

Aftercare and Recovery

After the procedure, you’ll be monitored for a short time to ensure you don’t have any complications. You may need to lie flat for a while to prevent bleeding at the insertion site. Follow your doctor’s instructions carefully regarding activity levels, diet, and any medications to avoid.

Why This Test Is Done

Doctors perform this test to diagnose or monitor conditions like kidney artery blockages, kidney disease, or vascular issues that may affect blood flow to the kidneys. It can also help evaluate kidney transplant patients for vascular complications.

Frequently asked questions

How long will I need to rest after this procedure?
You’ll typically need to rest for a few hours, often until you’re fully awake and alert. Your doctor will give specific instructions based on your case, but lying flat for 1–2 hours is common to prevent bleeding at the insertion site.
Will I feel any pain or discomfort during or after the procedure?
You may feel a brief pinch or pressure during the insertion of the catheter, but the procedure itself is usually painless. Some mild discomfort or bruising at the insertion site may occur afterward, but this is normal and should resolve within a few days.
Can I drive or operate heavy machinery after this test?
No, you should avoid driving or operating heavy machinery until your doctor says it’s safe. This is because you may have been sedated, and your alertness could be affected. Follow your doctor’s specific recovery instructions.
