Living with prostate cancer

Bladder problems after treatment for prostate cancer

You might have problems passing urine after prostate cancer treatment. 

Possible problems depend on what treatment you have. Your doctor will tell you about the treatment side effects. These can include:

  • leaking urine

  • bladder inflammation

  • difficulty passing urine

Your healthcare team will tell you what you can do to help with these problems. This includes muscle exercises, bladder training, surgery or medicines.

Help and support with leaking urine

Leaking urine is one of the most common problems after prostate cancer surgery. You might find it difficult to cope with this side effect. But there are things you can do and people who can help you and your family to cope.

Who can help you

Your doctor or specialist nurse can refer you to a continence clinic if this becomes a problem. They can help you with pelvic muscle exercises and bladder training.

Pelvic floor exercises

Pelvic floor exercises target and strengthen the muscles that control your bladder. Your doctor or specialist nurse will talk you through what to do. Research has shown that pelvic floor exercises can help you stop or reduce urine leakage.

If you have not had information about pelvic floor exercises, ask your specialist nurse. Or ask to see a physiotherapist that can talk you through them.

You can find out more about how to do pelvic floor exercises on the NHS website.

Drink plenty of fluids

Don’t cut down on your fluids, drink at least 2 litres a day. You can drink plenty during the day, but it might help to limit fluids 2 hours before bedtime. Drinking plenty helps your bladder regain its tone.

Incontinence pads and sheets

You might need to wear pads when you first start going out. There are different types of pads. You might be able to get some pads for free on the NHS, although this may depend on the service in your area. Some GP practices have a continence nurse you can see.

It can also help to visit places where you know there are toilets. Or you can telephone beforehand to find out about toilets and how easy they are to get to.

You might find it useful to get some incontinence sheets for your bed. This might not be necessary but could be reassuring. You could try a urinary sheath. The sheath looks a bit like a condom with a hole at the end. It fits on your penis and is connected to a tube and bag. Any leaked urine can drain into the bag. This might be particularly useful at night to help you sleep better.

'Just can’t wait' card

You can get a card to show to staff in shops or pubs etc. It allows you to use their toilets, without them asking awkward questions. You can get the cards from Disability Rights UK or the Bladder and Bowel Community. They also have a map of all the public toilets in the UK.

You could get a key to disabled toilets if you need to access them quickly. You buy the RADAR key from Disability Rights UK. But this should only be used by people who need quick access to a disabled toilet due to a disability or medical condition.

Tips

  • Plan your trips out.

  • Find out where the toilets are.

  • Take extra pads and spare underwear.

  • Organise a ‘Just can’t wait card’ or key for disabled toilets if you need it.

  • Do your pelvic floor exercises regularly.

Bladder training

Bladder training encourages your bladder to hold larger amounts of urine for longer periods of time. You keep a diary of when you go to the toilet and gradually increase the time between each visit.

Artificial urinary sphincter

Your doctor might suggest that you have surgery to fit an artificial urinary sphincter (AUS). This might be an option if:

  • your urinary leakage is severe

  • other methods, such as pelvic floor exercises and bladder training, do not help

During the operation your doctor puts an inflatable ring around the urethra. The ring attaches to a small pump in your scrotum. You use this to deflate the ring when you want to pass urine.

This device could reduce the amount of urine leakage or stop it altogether. But the operation can be difficult. You can discuss this with your urologist.

Help and support with bladder inflammation (cystitis)

Radiotherapy inflames the lining of your bladder and the urethra. This is called radiation cystitis. It can mean you need to wee more often or burn when you wee.

Let your doctor know if you have these symptoms. Particularly if your urine is cloudy or smelly. This could be a sign of infection. 

Radiation cystitis usually gets worse during radiotherapy and for a few weeks afterwards. You should start to feel better within a few weeks or months of finishing. Some men might have more delayed side effects. Urinary problems can develop months or years later. You have a higher risk of side effects if you have internal radiotherapy as well as external radiotherapy.

Who can help you

Talk to your doctor if you have bladder problems. They can refer you to a continence clinic. They can help you with muscle exercises, bladder training and medicines. Other treatments may also be available, depending on your situation.

Drink plenty of fluids

Drink at least 6 to 8 glasses each day. Don’t cut down on your fluids. You can drink plenty during the day, but it might help to limit fluids 2 hours before bedtime.

Some people think that cranberry juice can help but others feel it makes the soreness worse. Research studies haven’t found that it helps. Don’t drink cranberry juice if you are taking warfarin.

You might find that some drinks increase the soreness, such as tea and coffee. You can experiment for yourself and see what works for you. Don’t take potassium citrate, which is an old fashioned remedy for cystitis. You might hear it called mist pot cit for short. This drug can be very harmful if taken in large amounts.

'Just can’t wait' card

You can get a ‘Just can’t wait’ card to show to staff in shops or pubs etc. It allows you to use their toilets, without them asking awkward questions. You could get a key to disabled toilets if you need to access them quick.

You can get the cards and key from Prostate Cancer UK, Disability Rights UK or the Bladder and Bowel Community. They also have a map of all the public toilets in the UK.

Bladder training

Bladder training encourages your bladder to hold larger amounts of urine for longer periods of time. You keep a diary of when you go to the toilet and gradually increase the time between each visit.

Medicines

Your doctor might prescribe medicines if they are likely to help your symptoms. For example, you might have a medicine from a group of drugs called anticholinergics or alpha blockers. They help to relax the bladder muscle. They help the bladder to hold more urine before you feel the need to go, and making it easier to pass urine.

Implanted sacral nerve stimulation

Your doctor puts thin wires (electrodes) on your lower back. This sends gentle pulses of electrical signals to the nerves that control passing urine. If this helps you, a permanent nerve stimulator is then put into your buttock area.

Surgery to remove the prostate gland

Surgery to remove your prostate gland is called radical prostatectomy. Most people in the UK have robotic assisted keyhole surgery.

Radiotherapy for prostate cancer

Radiotherapy uses high energy waves similar to x-rays to kill prostate cancer cells. You might have external beam radiotherapy or internal radiotherapy (brachytherapy).

Living with prostate cancer

Get practical and emotional support to help you cope with a diagnosis of prostate cancer, and life during and after treatment.

Sex and relationships after prostate cancer treatment

Prostate cancer treatments can affect your sex life in different ways. Some treatments can damage the nerves or affect hormone levels that you need to get an erection.

Prostate cancer support organisations

There are organisations, support groups, videos and other resources to help you cope with prostate cancer and its treatment.

Prostate cancer main page

Prostate cancer is cancer that starts in the prostate gland. The prostate gland is found at the base of the bladder and is about the size of a walnut.
