Kidney embolisation

Kidney embolisation is normally carried out under local anaesthetic. Your surgeon's techniques may vary but they may follow this process:

Your consultant surgeon will start by making a small incision in the groin area, before inserting a catheter (long, thin tube) into the blood vessel. Using X-ray images, they will then inject a fluid (blocking agent) into the blood vessel through the catheter. This fluid blocks the blood supply to the kidney area that is to be embolised (obstructed).

This can take up to three hours. Pain relief medication may be given to you during this time. At the end of the procedure, your consultant surgeon will remove the catheter. Pressure may be applied to the incision area to stop bleeding.

Your consultant will explain the procedure and answer any questions you might have. You will have blood and urine tests beforehand to ensure you are not at risk during kidney embolisation. You may be advised to not eat anything four hours prior to treatment. You should be able to drink water up to two hours before.

Intravenous fluids are passed into your blood stream around two hours before the procedure. If you take painkillers, blood thinning medication or anticoagulants, your consultant will advise you on when to stop taking these. It is normally stopped or your dose will be adjusted at least one week prior to the procedure.

You will remain in hospital for monitoring after kidney embolisation. Your consultant and nurses may check the following:

• Swelling and/or bleeding in the groin area where the catheter was inserted.
• Blood pressure, circulation, pulse and temperature.
• If you experience any pain or discomfort.
• The amount of oxygen in your blood.

You may also be given a urinary catheter to drain urine from your bladder. This helps your consultant to ensure blood and urine levels around your kidneys are sufficient When you are ready to go home, your consultant may give you medication to assist your recovery. They will also advise you on follow-up appointments.
