Advice after your nerve block for surgery
On this page…
Introduction
We have been advised by your hospital consultant that you need to have a Prostate Artery Embolisation. These are done in the radiology department by Interventional Radiologist (doctor specialising in medical imaging) by guiding a needle into the body under ultrasound and fluoroscopic control to accessing a vessel to be able to guide wires and small plastic tubes (catheters) into the correct location. The procedures will be performed by a radiologist who will be assisted by radiographers and radiology nurses.
This information tells you about having the procedure, what is involved, and what the possible risks are. This is not intended to replace the discussion between you and your consultant, but may act as a starting point for discussion. If after reading this information you still have concerns or require further explanation, please contact us using the telephone number on your appointment letter, or ask the ward staff.
What is a Prostate Artery Embolisation?
The prostate gland is located below the urinary bladder and surrounds the thin muscular tube (urethra) through which urine passes when you urinate. Enlargement of the prostate gland can lead to a blockage of the flow of urine and produce various symptoms, including reduced urine stream and frequent need to urinate during the night. This can be improved with medication or an operation via the urethra (transurethral resection of prostate (TURP)).
PAE is a minimally invasive, non-surgical way of treating an enlarged prostate gland by blocking off the blood flow to the small arteries supplying the prostate gland making it shrink and allowing a better flow of urine. This is achieved with an injection of small particles into the arteries that supply the gland PAE can also be used for controlling bleeding from the prostate gland. The decision was made by your urologist and an interventional radiologist who is going to perform the procedure.
In addition to the standard tests for prostate enlargement, you will need to have a special CT scan (CT angiogram) to help us visualise the arteries in your pelvis. This will help the radiologist to decide if the anatomy of your arteries is suitable for the treatment.
What is Fluoroscopy?
Fluoroscopy is a process that uses X-rays to produce a real time moving image on a
television monitor.
What is Ultrasound?
An ultrasound scan is an examination that uses sound waves to take pictures of the part of the body being examined. It does not involve X-rays.
What is a CT scan?
A CT scan is an examination using X-rays by lying on a flat table inside a scanner that
produces detailed cross sectional images of your body. These images are cross-sectional (like slices) and are used to produce 2D and 3D images of the body’s organs
Before your appointment
Please let us know if:
- you are taking any medication which impair the bloods ability to clot (anticoagulation or blood thinning drugs) e.g. Warfarin or clopidigrel, or, if you are aware that you may have bleeding problems. The radiologist who will be performing your examination can be notified and may need to discuss this with you and your hospital consultant before your appointment can be confirmed as the medication may need to be stopped or changed before the procedure. The Interventional nursing team can be informed on 0300 613 2161 (Frimley) or 0300 615 3544 (Wexham).
Please also let us know if:
- you have limited mobility and will require assistance to get on and off the scanner.
- you will need an interpreter. We are not able to use family members or friends to interpret.
- there is any possibility that you may be pregnant.
- you are diabetic - please note that you are required to starve before the examination. You may be given an early morning appointment or alternative medication will be given on the ward.
In order to make your appointment run more smoothly, please let us know if any of these apply, in advance, by calling our bookings team (contact details are displayed on the main Radiology page).
Please review the contrast safety questionnaire enclosed in this letter and fill this in before your appointment. This can be completed on paper and where indicated this can also be completed online.
Food and Drink
You may have a light very early breakfast on the day of your appointment. Please do not eat or drink anything, except a little water if necessary, for four hours before your appointment.
What to bring with you
You will usually be admitted for the procedure as a day case. Occasionally it is necessary for patients to stay overnight in hospital after the biopsy. For this reason we advise that you prepare an overnight bag and bring this with you. You may wish to bring your own dressing gown, slippers and reading material.
Please bring with you to your appointment any sprays or inhalers that you are taking. Please bring a list of any regular medications you are taking
During the procedure
Referral and consent
You will be asked to sign a consent form confirming that you understand the procedure and are aware of the risks and benefits involved. Where practical this is usually done on the ward, before you come to the Radiology Department or in an outpatient clinic environment before your admission to hospital for the procedure.
The procedures are normally done as a planned procedure and you should have plenty of time to discuss the situation with your doctor or the nurse specialist looking after you before you sign the consent form. When you arrive for the procedure you will also discuss the procedure with the radiologist who will be performing the procedure who will again sign the consent form with you.
If after discussion with your hospital doctor or radiologist, you do not want the procedure carried out, then you can decide against it. If the radiologist feels that your condition has changed or that your symptoms do not indicate such a procedure is necessary then they will explain this to you and they will communicate with the referring doctor who will review your situation as soon as possible. At all times the radiologist and referring doctor will be acting in your best interests.
Procedure
You may need a cannula (small tube) inserted into a vein in your arm to allow access for fluids and for administering medication.
You will need to wear a hospital gown. The Porters will collect you from the ward and bring you to the X-ray Department, on your bed, for the procedure.
The procedure will be explained to you by the radiologist. You will be able to ask any further questions that you may have.
You will be asked to lie on the examination table. It is important that you stay very still until the procedure is over. If you are uncomfortable please let the doctor know.
After the procedure
Once you have returned to your ward, nurses will carry out close and regular observations, such as taking your pulse, blood pressure and temperature, to make sure that there are no problems. You may be required to stay in bed for at least four hours. You should tell the nurses if you feel worsening pain or a rise in your body temperature.
You should drink plenty of fluids and eat normally
If you have any problems after the procedure please speak to the staff on the ward or contact your GP or emergency doctor if problems occur when you have returned home.
How long does it take?
As an approximate guide, expect to be in the Radiology Department for about 45 minutes to one hour. However much of this time is taken up by preparation rather than the procedure itself. You will normally be expected to rest on the ward for at least four hours after the procedure. If you have been admitted specifically for this procedure as a day case patient, you should then be able to go home. In some cases you may be asked to stay overnight.
Risks
As with any procedure or operation, complications are possible. The possibility of these occurring will vary for each patient and the possibility of these happening to you will be discussed with you, before you sign the consent form.
Bleeding: Any interventional procedure carries a small risk of bleeding.
Infection: Occasionally there may be infection in the area surrounding the biopsy site.
X-rays are a type of radiation. We are all exposed to natural background radiation every day from the sun, food we eat, and the ground. Exposure to medical X-rays carries a small additional risk, but your doctor feels that this risk is outweighed by the benefits of having the test and the amount of radiation you will receive is kept to as low as reasonably possible.
