One-piece urostomy pouches in Canada — shop pouches designed for urinary diversions where the barrier and pouch are built as a single unit. One-piece systems are quick to apply, sit low-profile against the body, and are a popular choice for people who prefer a simple, streamlined pouch change.
Who are 1-piece urostomy pouches for? If you have a urostomy (ileal conduit or similar urinary diversion) and want a system with fewer components, one-piece pouches combine the skin barrier and collection pouch into one unit. They tend to be more flexible and less bulky than 2-piece systems. If you prefer to change the pouch without removing the barrier each time, a 2-piece urostomy system may be a better fit.
What to look for: Urostomy pouches have a tap or valve at the bottom for draining urine without removing the pouch. Check the barrier type (flat vs. convex), the stoma opening (pre-cut vs. cut-to-fit), and whether the pouch is transparent or opaque. Match the stoma size to your measurement and confirm compatibility with your current system if reordering.

1-Piece Urostomy Pouches FAQ
What is a 1-piece urostomy pouch?
A 1-piece urostomy pouch combines the skin barrier (wafer) and the collection pouch into a single unit. When you change the pouch, you remove and replace the entire system. This makes pouch changes straightforward — there's only one component to position and apply.
1-piece vs. 2-piece urostomy — which should I choose?
One-piece systems are thinner, more flexible, and quicker to change. Two-piece systems let you swap the pouch without removing the barrier from your skin, which can reduce skin irritation from frequent changes. Many people choose based on their lifestyle, skin sensitivity, and how often they prefer to change.
What is the difference between flat and convex barriers?
Flat barriers sit flush against the skin and work well for stomas that protrude above the skin surface. Convex barriers have a gentle outward curve that presses the surrounding skin down, which helps create a better seal for stomas that are flush, retracted, or sit in a skin fold or crease.
How do I drain a urostomy pouch?
Urostomy pouches have a tap or valve at the bottom that you open to drain urine into the toilet or a container. Most people drain their pouch when it's about one-third full to prevent the weight from pulling on the barrier. At night, the pouch can be connected to a night drainage bag for continuous drainage while you sleep.
How often should I change my 1-piece urostomy pouch?
Most manufacturers recommend changing a 1-piece urostomy pouch every 1 to 3 days, though this varies by product and individual factors like skin condition, activity level, and output. Signs it's time to change include reduced adhesion, lifting edges, or skin irritation. Always follow the manufacturer's instructions and your clinician's guidance.
