This leaflet has been produced to give you general information. Most of your questions should be answered by this leaflet. It is not intended to replace the discussion between you and the healthcare team, but may act as a starting point for discussion.

Introduction

This leaflet has been produced to provide specific information for those patients with cancer within the pelvic area who have been referred for Computed Tomography (CT) planning prior to their radiotherapy treatment. It provides details of preparation required before you attend your CT and treatment appointments. If after reading it you have any concerns or require further explanation, please discuss this with a member of the healthcare team caring for you.

Why do I need to have an empty rectum and a full bladder?

Your course of radiotherapy will be planned on an individual basis using special CT Planning scans.

The organs within your pelvis, for example the uterus (female) or prostate (male) will naturally change position slightly, depending on how full your rectum W bladder are. Therefore, in order to give radiotherapy directly to the identified area, it is important that it is in the same position for all your treatments as it was for your CT planning scan. The most effective way to ensure this, is for you to have an empty rectum (bowels) and a comfortably full bladder for each appointment.  This will be checked with daily imaging before your radiotherapy, to ensure positioning of the treatment is accurate. You may have more than one scan if your bladder and bowel positions are not suitable.

How do I prepare for the CT planning scan and daily radiotherapy treatment?

Guidance to keep your bladder full

Ideally you should feel comfortable whilst keeping the bladder full and not straining yourself to hold urine. Hydration is a very important factor.  If you are not well hydrated before you drink your water for the treatment, hardly any water will pass to the bladder. As a guide we recommend you drink 500ml of water in the morning before your appointment.

We suggest if you are traveling a long distance to your appointment, you should empty your bladder just before leaving home. To enable your bladder to fill sufficiently, please allow extra time before your appointment time where possible.

On arrival in the department, please empty your bladder and wait for further instructions from the radiographers who will be conducting your CT planning scan.  This will need to be repeated everyday whilst attending for your treatment.

Please inform the radiographers before the CT planning scan or daily radiotherapy treatment if you have or have not been able to do this.

What if I cannot hold water for more than one hour?

If you have difficulty holding urine, we may need to amend the type of preparation for your treatment. If you feel this applies to you, please tell the radiographer at your CT planning appointment before the procedure takes place.

Guidance to keep your rectum (bowel or back passage) empty

There are various ways of keeping your rectum empty.  Your consultant will suggest one of these methods, even if your bowels are opened regularly:

Method 1: Taking any laxative (e.g. Movicol)

Start taking the Movicol 3 days before your CT planning scan appointment and then again 3 days prior to starting your daily radiotherapy treatment. Then continue to take the laxative during the course of your daily radiotherapy, or until advised by a medical professional.   It is usual to take the laxative at night, before going to bed.

Method 2: Glycerin suppositories

Use a Glycerin suppository (inserted via the back passage) at least one hour before you leave home on the day of your CT planning scan. Then continue taking every day whilst having your daily radiotherapy sessions. Again, use at least one hour before you leave home, to allow it to work before starting a journey to the Castle Hill Hospital.

Suppositories should be taken at least 1 hour before you leave your home because it will take 15-45 minutes to work.  If you have a long distance to travel, it is worth having a practice using them 1-2 days before your CT planning scan so you will know how long they take to work. We suggest that you moisten the suppository under running water before you insert it into your back passage following the instruction leaflet.

What if the suppositories do not work or are uncomfortable to use?

Laxatives or suppositories must be used before your CT planning appointment and also before each radiotherapy session. If you find that you are uncomfortable using suppositories or they are not working, please discuss this with your treatment radiographer or speak to the specialist nurse within the radiotherapy department, as alternative laxatives may be prescribed.

Method 3: Fybogel

Start taking Fybogel 5 days before your CT planning scan. On the day of your CT planning scan use the Glycerin suppository at least one hour before you leave home. Then keep taking Fybogel the night before each of your daily radiotherapy session.

Method 4: Enema

Enemas can be given for patients struggling to empty their bowels. A phosphate enema is a very fast acting enema and is given in the department. Micro enemas are a slower acting enema and are usually given 1 hour before CT and treatment and takes 20 minutes to work.

What if I start having diarrhoea?

One of the side effects of radiotherapy is diarrhoea or loose stools. Generally this symptom starts around the 2nd or 3rd week of radiotherapy treatment. If you have loose stools, please discuss it with treatment staff or radiotherapy nursing team at your next appointment, you may also stop your bowel preparation.

When do I stop using suppositories and laxatives?

If you start getting diarrhoea more than 3 times a day, uncomfortable back passage soreness, abdominal cramps or abdominal pain then stop using Glycerin suppositories and laxative and inform the radiographer or nurse.

What will happen at my CT planning scan appointment?

Full information regarding your scan can be found in the ‘Introduction to Radiotherapy CT Planning’ booklet which can be given to you by a member of staff.

What will happen at my treatment appointments?

You will be required to repeat the drinking and bowel preparations process that you are asked to do at your CT planning scan. A radiographer will run through any individual process on your first day of treatment.

Dietary advice whilst attending for CT planning and radiotherapy treatment

It is advisable to reduce a high fibre diet e.g. fruits and vegetables with the skins left on and any type of food that causes excessive gas formation for your CT planning scan and during your radiotherapy treatment. We advise reducing these types of foods 2-3 days before your CT planning appointment and again 2-3 days before commencing your daily radiotherapy treatment and during the full course of your daily radiotherapy. We would wish you to avoid excess gas as this too can change the position of your internal organs e.g. bowels.

Gas (wind) in the bowel

As part of the preparation for your radiotherapy we need you to try to limit the amount of gas in your bowel.  Air in the digestive tract is perfectly normal – everyone has it.  Gas enters the bowel either by swallowing or by the breakdown of certain foodstuffs. Some foods that cause gas in some people will not in others.

We do not want you to make drastic changes to your diet or lifestyle but the following advice may be helpful before and during your radiotherapy.  Reduce the amount of air you swallow by:

  • avoiding chewing gum
  • avoiding fizzy (carbonated) drinks
  • avoiding eating and drinking too fast

Reduce the amount of air caused by food breakdown by limiting the amount you eat of the following products although it will not harm you to eat them in moderate amounts:

  • nuts/seeds
  • beans
  • broccoli
  • onions
  • mushrooms
  • cabbage
  • cauliflower
  • raisins
  • lentils and pulses
  • prunes
  • brussel sprouts
  • fruit juices containing ‘bits’
  • ‘sugar free’ products containing sorbitol or mannitol (this is displayed on packaging)

Try to keep portions of fruit to two per day.

Should you require information on the appropriate types of food we are indicating please ask a member of staff for guidance.  We also suggest that you avoid coffee, tea and alcohol 2-3 hours before going to bed as this may help in reducing excessive night time frequency of passing urine. You may still drink water.
