Angiography > Exams & Procedures > Kidney/Renal Angiogram

This is an arterial study to look at the blood vessels that supply your kidneys. Local anaesthetic is given into the skin to numb the area. A small, thin tube commonly called a catheter is inserted in an artery, usually in the groin region. The catheter is placed in a position to view the kidney's blood vessels. The vessels are viewed with the injection of contrast through the catheter.

Once the radiologist has viewed the pictures taken during the study, he/she will then press at the puncture site for 10 minutes.

The procedure takes about one hour. You will be on bed rest for three hours after the procedure.

Preparation

  • If you are diabetic, do everything you would normally do. Do not take your metformin. A blood test will be done once you arrive in hospital.
  • If you are not diabetic, do not have anything to eat or drink after midnight.
  • If you are taking aspirin, Coumadin, Tyclid, Plavix or Aggrenox please stop taking this medication one week before, but only with your doctor's approval.
  • Please take all of your medications with a small amount of water, especially heart and blood pressure medications.
  • If you have had a previous allergic reaction to contrast media (X-ray dye), please inform us and your doctor in advance. Your doctor may order a medication for you to take prior to your procedure.
