Changing a urostomy bag is a straightforward process once you get the routine down. Most people change their pouching system every three to five days, with the national average sitting right around five days of wear time per pouch. The key is having your supplies ready, working efficiently (since urine flows continuously from the stoma), and getting a good seal each time.
Gather Your Supplies First
Before you remove anything, lay out everything you’ll need within arm’s reach. Running to grab a forgotten item while urine drips from an exposed stoma is frustrating and messy. Here’s what to have ready:
- New pouching system (pre-cut or ready to cut)
- Stoma measuring guide
- Scissors (if using a cut-to-fit barrier)
- Rolled gauze or paper towels to wick urine during the change
- Warm water and a soft cloth or gauze for cleaning
- Sealable plastic bag for the used pouch
You can change your pouch sitting, standing, or lying down. Many people prefer standing over a toilet so any dripping urine goes right into the bowl. Others sit on the toilet lid or stand at a counter with a mirror. Try different positions early on to find what works for your body.
Remove the Old Pouch
Start by emptying the pouch through its drain valve if there’s still urine inside. Then gently peel the skin barrier away from your body. The important technique here: push your skin down and away from the adhesive rather than pulling the pouch off your skin. Pulling upward can irritate the skin over time and even cause small tears, especially if you’re changing frequently.
If the adhesive feels stubborn, you can use an adhesive remover wipe to loosen it. Work slowly around the edges. Once the pouch is off, place it in a sealable plastic bag and toss it in the regular trash.
Clean the Stoma and Surrounding Skin
Tuck a piece of rolled gauze or a folded paper towel against the base of the stoma to absorb urine while you work. Urine will keep flowing since a stoma has no sphincter muscle to hold it back, and the gauze gives you a dry workspace.
Clean the skin around your stoma with warm water and a soft cloth. Avoid moisturizing soaps, lotions, oils, or alcohol-based products, as these leave residue that interferes with adhesion. If you want something beyond plain water, use a soap-free, residue-free cleanser designed for ostomy care. Pat the skin completely dry with a soft cloth afterward. Some people use a hairdryer on a cool setting for 10 to 15 seconds to make sure no moisture remains.
While the skin is exposed, take a moment to look at both the stoma and the surrounding skin. The stoma should be pink or red and moist. The skin around it should look similar to skin elsewhere on your abdomen. If you notice redness, wetness, itching, or any breaks in the skin that don’t heal within a week, contact a wound, ostomy, and continence nurse.
Measure and Prepare the New Pouch
Your stoma can change size, especially in the first several months after surgery. Use your measuring guide each time you change the pouch, at least until your stoma has stabilized. Find the smallest opening on the guide that fits around the stoma without touching it. You want roughly 1/8 inch of clearance between the edge of the stoma and the edge of the barrier opening. Too much exposed skin inside that opening leaves it vulnerable to contact with urine, which causes irritation. Too tight and the barrier presses against the stoma itself.
If you use a cut-to-fit system, trace the correct size onto the back of your skin barrier and cut it out with scissors. Pre-cut systems skip this step since the opening is already sized, but they require that your stoma dimensions stay consistent.
Apply the New Pouching System
Remove the backing from the adhesive skin barrier. Center the opening directly over your stoma, working from the bottom up so you can see what you’re doing. Press the barrier firmly against your skin, starting closest to the stoma and smoothing outward. Hold your hand flat against the barrier for 30 to 60 seconds. Your body heat helps activate the adhesive and creates a better seal.
If you use a two-piece system, attach the pouch to the flange on the barrier once the barrier is secured to your skin. You should hear or feel a click when the coupling snaps into place. Give the pouch a gentle tug to confirm the connection is secure.
Make sure the drain valve at the bottom of the pouch is closed. This is easy to forget, and an open valve means urine dripping down your leg within minutes.
One-Piece vs. Two-Piece Systems
A one-piece system combines the skin barrier and pouch into a single unit. It sits flatter against the body and tends to be less visible under clothing. The tradeoff is that every pouch change means removing and reapplying the adhesive barrier, which can matter if your skin is sensitive.
A two-piece system uses a separate barrier (called a flange or wafer) that stays on your skin while you snap pouches on and off. This means you can swap out the pouch without disturbing the barrier every time, which reduces skin irritation. You can also switch between different pouch sizes or styles while keeping the same barrier in place. Some people find the flange connection a bit bulkier under clothing. Both systems work well for urostomies, and many people try a few options using free samples before settling on a preference.
Improving Your Seal
A leaky seal is the most common frustration with any ostomy pouching system, and urostomies are especially unforgiving because urine is constantly flowing. If your pouch keeps lifting at the edges or you notice moisture creeping under the barrier, a few adjustments can help.
First, make sure your skin is truly dry before application. Even a thin film of moisture can prevent the adhesive from bonding properly. Second, reconsider barrier wipes. They create a thin protective layer on the skin that can actually build up with repeated use, making the surface less tacky. If your skin is intact and healthy, try going without barrier wipes for a few changes and see if adhesion improves.
For more persistent leaking, accessories like barrier rings (moldable rings that fill in uneven skin contours around the stoma) or ostomy paste can help create a tighter seal. A wound, ostomy, and continence nurse can assess your specific stoma shape and skin condition to recommend the right combination of products.
Connecting a Night Drainage System
Because urine collects continuously, a standard urostomy pouch can fill overnight and either leak or cause backflow toward the stoma. A night drainage system solves this by connecting tubing from your pouch to a larger bedside container that holds urine while you sleep.
Set up the drainage container and tubing before connecting anything to your pouch. Your pouch should be about one-quarter full when you attach the system, so the urine flows downward through the tubing by gravity. Some systems come with the tubing and container as one piece, while others require you to insert the tubing into the container lid separately. A leg strap can keep the tubing from twisting or kinking during the night, which would block drainage.
In the morning, disconnect the tubing from your pouch, empty and rinse the container, and close your pouch’s drain valve. Many people also use a leg bag during the day for longer outings, using the same type of connection.
When to Change Your Pouch
Most people get three to five days from each pouching system, though some go longer depending on their skin, activity level, and the products they use. Change your pouch on a schedule rather than waiting for a leak. If you notice the edges starting to lift, itching under the barrier, or any odor, change it sooner rather than pushing for another day. Morning is often the best time, since you’ve been lying down and urine output tends to be lower right after waking (before you start drinking fluids).
