Changing a urostomy bag is a routine task that becomes easier with practice. The basic steps are: gently remove the old pouch, clean and dry the skin around the stoma, apply a new skin barrier and pouch, and ensure the seal is secure. Most people complete a full change in five to ten minutes once they are comfortable with the process. This guide walks through each step in detail so you can manage your urostomy with confidence.
What You Need Before You Start
Gather all your supplies before you begin. Running out of something mid-change is frustrating and can leave your skin exposed longer than necessary.
Your basic supplies include:
- New urostomy pouch and skin barrier (wafer)
- Gentle cleanser or plain warm water
- Soft washcloth or gauze pads
- Disposal bag for the old pouch
- Scissors (if your barrier needs cutting to fit)
- Stoma measuring guide
- Skin barrier wipes or paste (if your clinician recommends them)
Some people also keep a mirror nearby to see the stoma clearly. A handheld mirror helps you check the underside of the barrier as you apply it.
How To Change Your Urostomy Bag Step By Step
Start by washing your hands thoroughly with soap and water. Clean hands reduce the risk of introducing bacteria to the stoma or the skin around it.
Remove the old pouch gently. Push the skin away from the adhesive rather than pulling the pouch away from the skin. This is easier on your skin and less likely to cause irritation. Some pouches have an adhesive remover wipe that makes this step much more comfortable. If you have one, use it by peeling the edge of the barrier and wiping the remover along the seal as you go.
Dispose of the old pouch in a trash bag or a disposable pouch designed for ostomy waste. Do not flush urostomy pouches or their contents down the toilet unless the product label specifically says it is flushable. Most are not.
Clean the skin around the stoma with warm water. Use a soft washcloth or gauze. Pat the area dry gently. Do not rub. The skin should be completely dry before you apply a new barrier because moisture prevents the adhesive from sticking well.
Check the stoma itself. A healthy stoma is pink or red, like the inside of your mouth. It may bleed slightly when touched — this is normal because the stoma has many tiny blood vessels close to the surface. If you see significant bleeding, dark discoloration, or unusual changes, contact your healthcare provider.
Measure the stoma with your measuring guide. The opening in your skin barrier should be about 1/8 inch larger than the stoma itself. This allows room for the stoma to swell slightly without the barrier rubbing against it. If your barrier needs cutting, trace the correct size and cut it with scissors. Some barriers come pre-cut in standard sizes.
Apply the new skin barrier. Center the opening over the stoma and press the barrier firmly against your skin. Hold it in place for 30 to 60 seconds. The warmth from your hand helps the adhesive bond to your skin.
Attach the pouch to the barrier if it is a two-piece system. If you use a one-piece system, the pouch and barrier are already connected. Press the pouch onto the barrier until you hear or feel it click into place. Give the connection a gentle tug to confirm it is secure.
Close the bottom of the pouch. Most urostomy pouches have a drain spout at the bottom that you fold and secure with a closure. Make sure it is fully sealed before you finish.
How Often Should You Change the Pouch?
Most people change their urostomy pouch every two to three days. Some change it daily. Others can go four days. The right frequency depends on your skin, the type of pouch you use, and how well the seal holds.
You should empty the pouch more often than you change it. Most people empty the pouch when it is one-third to one-half full. Urine is heavy, and a full pouch can pull on the adhesive and cause leaks. Emptying it regularly also prevents the weight of the pouch from straining your skin.
Change the pouch sooner if you notice any of these signs:
- The seal is lifting or peeling
- Urine leaks underneath the barrier
- The skin around the stoma feels itchy or burns
- The pouch has an odor that does not go away with cleaning
Do not wait for a leak to change the pouch. A leak exposes your skin to urine, which can cause irritation and breakdown. Skin that stays damaged makes it harder for the next barrier to stick.
Caring for the Skin Around Your Stoma
The skin around your stoma should look healthy and intact. If it becomes red, sore, or weepy, something in your routine needs adjustment.
Urine is acidic and contains waste products. When it sits against the skin, it can cause chemical irritation. This is why a proper seal matters so much. The barrier should fit snugly around the stoma with no gaps where urine can reach the skin.
If you notice skin irritation, check the size of the opening in your barrier. An opening that is too large exposes skin to urine. An opening that is too small can rub against the stoma and cause bleeding or discomfort.
Some people develop a rash or itching from the adhesive itself. If this happens, talk to your wound care nurse or ostomy nurse. They can recommend different barrier products or skin protectants. Do not use creams or lotions around the stoma unless your clinician says it is safe. Many moisturizers contain oils that prevent adhesive from sticking.
Managing Leaks and Odor
Leaks are the most common frustration for people with a urostomy. They happen to nearly everyone at some point, especially in the first few weeks after surgery.
Most leaks happen because the barrier does not fit well or the skin underneath is not completely dry. Take time with each step. Rushing the drying process is one of the most common causes of failed seals.
Another common cause is weight changes. If you gain or lose weight, the shape of your abdomen changes. A barrier that fit perfectly last month may not fit now. Re-measure your stoma and check the fit of your barrier regularly.
Odor is less of a problem with modern urostomy pouches than it was in the past. Most pouches have filters that release gas without releasing odor. When you empty the pouch, empty it into the toilet and flush. Some people add a few drops of ostomy deodorant to the pouch, but this is a personal preference rather than a medical necessity.
If you notice a strong, persistent odor even when the pouch is clean and sealed, tell your healthcare provider. This can sometimes signal a urinary tract infection, which is more common in people with a urostomy.
When to Contact Your Healthcare Provider
Most urostomy care is routine, but some signs should prompt a call to your doctor or ostomy nurse.
Contact your provider if you notice:
- The stoma changes color, especially if it turns dark purple, blue, or black
- The stoma becomes unusually swollen or shrinks dramatically
- Bleeding that does not stop with gentle pressure
- Signs of infection in the skin around the stoma, such as increasing redness, warmth, or pus
- Fever, back pain, or cloudy and foul-smelling urine
- Difficulty inserting a catheter if you use one
These symptoms can indicate problems that need medical attention. Do not try to manage them on your own with home remedies.
It is also worth asking your healthcare team for a referral to a wound, ostomy, and continence nurse (WOCN) if you have not already seen one. These specialists have advanced training in ostomy care and can help troubleshoot leaks, skin problems, and product selection.
Tips for Changing Your Pouch Away From Home
You can change your urostomy pouch outside your home. It just takes a little planning.
Carry a small kit with you that contains one or two complete pouch changes, a small bottle of water, gauze, and disposal bags. Many ostomy supply companies sell travel kits. You can also use a small toiletry bag.
When you need to change the pouch in a public restroom, use a handicap-accessible stall if one is available. These stalls are larger and usually have a shelf where you can lay out your supplies. Clean the skin with bottled water if the sink is not within reach. Pat dry with gauze and apply the new barrier just as you would at home.
Dispose of the old pouch in a disposable bag and place it in the trash. Do not flush it.
Some people worry about changing a pouch in a public restroom because of privacy or cleanliness concerns. It is a normal and manageable task. With practice, it becomes as routine as changing a bandage.
Frequently Asked Questions
How long does it take to change a urostomy bag?
Most people complete a full pouch change in five to ten minutes once they are practiced. The first few changes may take longer as you learn the routine.
Can I shower with my urostomy pouch on?
Yes, you can shower with your pouch on. Water will not harm the pouch or the stoma, and most pouch adhesives hold fine in water.
What should the skin around my stoma look like?
The skin around your stoma should look like the rest of your abdominal skin — clean, dry, and free of redness or irritation. The stoma itself should be pink or red and slightly moist.
Why does my urostomy bag keep leaking?
Leaks usually happen because the barrier opening is the wrong size, the skin was not completely dry before applying, or the barrier no longer fits due to weight changes. Re-measure your stoma and check your application technique.
Changing a urostomy bag is a skill like any other. The first few times feel awkward. Within a few weeks, most people do it without thinking. If you struggle with leaks, skin irritation, or fitting issues, reach out to your healthcare team. There are many products available, and finding the right combination for your body is a process of trial and adjustment.
