Looking after your urostomy

If you have a urostomy Open a glossary item formed, you pass urine through an opening (stoma) in your tummy (abdomen). You wear a bag at all times to catch the urine as it leaves your body. You might have a urostomy after surgery to remove your bladder (cystectomy). 

You will need to learn how to look after it before you leave the hospital. The nurses and your stoma nurse can show you how to do it. 

Learning about your stoma

A stoma is an opening on your abdomen Open a glossary item. There are different types of stomas. A urostomy is a new way for you to pass urine. Your urine passes through the stoma and collects in a bag on the outside of your body.

Meeting the stoma nurse

Stoma nurses have experience in looking after different types of stomas. They help, support and teach you how to look after yours.

You might see your stoma nurse before your operation. They will show you the different types of urostomy bags Open a glossary item you can use. They might give you a stoma kit to practice on first.  

First few days

After your operation, your nurse will change your urostomy bags. This is until you can change them yourself. Your nurse will show you how to:

  • clean your stoma
  • change the bag
  • empty the bag

Going home with supplies

Before you leave the hospital, you'll get some urostomy bags to take home. They will also set up an ordering system for you to get the bags from a specialist delivery service. Or they may give you a prescription card to take it to your GP with the details of all the equipment you need.

Support at home

After you leave the hospital, your stoma nurse might visit you at home to make sure that you are coping. Or you may have a community nurse visit instead. Do ask for their help with any questions or difficulties you have. You’ll have the contact details of your nurse to contact if you have any issues or questions whilst you’re at home.

Most stoma care services have support in place for long term follow up Open a glossary item. And patients are easily able to contact them if they get new problems. This is because the aftercare is different after you have surgery compared to a year later.

Types of urostomy bag

There are 2 main types of urostomy bags:

  • 1 piece system
  • 2 piece system

Your stoma nurse will help you to find out which system is best for you. The bags are very flat and do not smell or rustle as you move around.

Under ordinary clothes no one can tell you are wearing one. The bag can stay in place for a few days at a time. It has a tap at the bottom so you can empty it into the toilet.

The 1 piece system

The 1 piece system has the bag, seal and adhesive patch. It can last for up to 3 days. However it is advised to change the patch daily.

The 2 piece system

The 2 piece system has a separate bag and adhesive wafer (flange).

The wafer is a soft, flat, plastic adhesive disc that sticks to the body. The bag clips or sticks onto the wafer. You can leave the wafer in place for up to 5 days and just change the bag every 2 to 3 days. However it is advised to change the wafer every 2 to 3 days, and the bag everyday or every other day.

How to change your urostomy bag

What you need

To fit a new bag, at first you need to cut a hole in the wafer or adhesive patch to fit your stoma. This can feel daunting, so before you go home your nurse will give you a supply of pouches which have already been cut to size. When your stoma has settled in size, you can get bags that are pre cut to fit.

The more accurate the fit, the less likely the bag is to leak. You get very good at this with practice. 

What you need:

  • your new bag and wafer (if you use one)

  • a measuring guide or the backing film of a pouch as a template

  • tissues or absorbent cloth

  • warm water and wipes

  • a disposal bag or newspaper

  • scissors

  • a small mirror for looking at your stoma

  • a jug to empty the contents of the bag you are wearing or a toilet

You may also need adhesive paste if you're changing your wafer or one piece bag. Or a barrier cream if you have any skin damage. 

It’s helpful to keep everything that you need in a bag or in one place. That way, you won't be halfway through and realise something important is missing.

Changing the bag

Your stoma nurse will show you how to change your bag. They make sure you know how to do it before you leave the hospital.

Changing your bag can be difficult at first. With practice you start to learn what you need and what works best for you. It helps if your partner or someone close to you understands how to manage a urostomy too. 

When changing your bag you don't have to worry about keeping everything sterile. This means keeping it completely free of all germs. But you should be as hygienic as possible. You should:

  • wash your hands
  • cut a hole in the wafer to fit your stoma if it hasn't already been pre cut
  • make sure the tap is closed on the new bag
  • drain your old bag
  • peel the old bag off carefully - you can use an adhesive remover to help with this
  • throw the bag away in your disposal bag or wrap it in newspaper
  • clean round your stoma with warm water and wipes
  • dry the skin thoroughly with tissues or absorbent cloth
  • if you use barrier cream, massage it in well or it might stop your bag sticking to your skin properly
  • check the size of your stoma with the measuring guide to make sure it hasn't changed - your stoma nurse will show you how to do this
  • peel off the paper from the flange
  • stick your new bag or wafer in place
  • press down on the flange with warm fingers for 5 to 10 minutes to make sure its sealed to your skin and there are no creases
  • place your rubbish in the bin
  • wash your hands

Get support

Some organisations can give you advice and support. For example, the Urostomy Association.

The Urostomy Association can arrange for you to meet with other people with urostomies. Members can visit you before and after your operation to support you and give advice on how to cope.

Meeting someone who has been through a similar experience might help you to cope. They know what is important to tell you. And they can answer your questions from first hand experience.

For support and information, you can call the Cancer Research UK information nurses. They can give advice about who can help you and what kind of support is available. Freephone: 0808 800 4040 - Monday to Friday, 9am to 5pm.
