What Is a 2-Piece Urostomy Kit?
A 2-piece urostomy kit provides the essential components of a urostomy pouching system — a skin barrier and a compatible urostomy pouch — designed to work together as a complete appliance. The skin barrier adheres to the skin around the stoma and couples to the pouch via a flange or adhesive ring. Because the barrier and pouch are separate components, you can change the pouch daily without removing the barrier from your skin, reducing irritation and extending wear time on the barrier itself. This collection includes urostomy skin barriers and pouches from Hollister and Coloplast.
Hollister New Image Urostomy Flextend Barriers
The Hollister New Image line features the Flextend skin barrier, which is designed to resist breakdown from urinary output — an important characteristic for urostomy users, as constant urine contact can erode standard barriers more quickly than stool output does with colostomy or ileostomy barriers. The Flextend barrier is available in sterile and non-sterile versions across three flange sizes (1-3/4", 2-1/4", and 2-3/4") to accommodate different stoma sizes and coupling requirements. Sterile barriers are indicated for specific clinical settings or post-surgical use; non-sterile barriers are appropriate for standard home use. The New Image system uses a floating flange design that allows the coupling ring to flex away from the body, making it easier to attach the pouch without pressing directly against the abdomen — a feature valued by users with tender peristomal skin.
Coloplast Assura Urostomy Pouch
The Coloplast Assura Transparent Urostomy Pouch is a 2-piece urostomy pouch designed to pair with Assura 2-piece skin barriers. It features a drain tap at the bottom for controlled emptying throughout the day and connects to a larger overnight drainage bag at night. The transparent film allows for stoma and output monitoring without removing the pouch. The Assura system uses a coupling ring that clicks securely into place on compatible Assura barriers.
Sterile vs. Non-Sterile Barriers
Sterile urostomy barriers are packaged and processed to eliminate microbial contamination and are commonly used in hospital or clinical settings, or as directed by a healthcare provider following surgery. Non-sterile barriers are the standard option for home use and routine ostomy management. For most people managing a urostomy at home, non-sterile barriers are appropriate and more cost-effective. If you have been specifically directed to use sterile supplies, follow your healthcare provider's instructions.
Finding Your Product
This is a small, focused collection. Flange size is the critical variable for the Hollister New Image barriers — confirm your existing flange size before ordering. The available sizes are 1-3/4", 2-1/4", and 2-3/4". The Coloplast Assura pouch is compatible with Assura 2-piece barriers only — confirm your barrier's coupling size before purchasing the pouch separately. If you need help identifying compatible components, contact us or speak with your ostomy nurse.
2-Piece Urostomy Kit FAQ
What is the difference between a sterile and non-sterile urostomy barrier?
Sterile urostomy barriers are individually packaged and processed to eliminate microbial contamination, making them suitable for clinical settings, post-surgical use, or situations where a healthcare provider has specifically required sterile supplies. Non-sterile barriers are the standard option for routine home use and are appropriate for the vast majority of people managing a urostomy day-to-day. Non-sterile barriers are functionally equivalent for home use and are generally more cost-effective. If you are unsure which option is appropriate for your situation, consult your ostomy nurse or healthcare provider.
What does the Flextend barrier material do differently for urostomy users?
The Hollister Flextend barrier is designed to resist erosion from continuous contact with urine, which can break down standard barrier materials more rapidly than stool output. Because a urostomy produces urine continuously throughout the day, barrier durability is a particularly important consideration for urostomy users. The Flextend material is intended to maintain its integrity and adhesion for longer under these conditions, helping to extend wear time and reduce the frequency of full barrier changes. Always follow the wear time guidance included with your specific product.
How do I know which flange size to order for the New Image barrier?
The flange size on your skin barrier must match the flange size on your urostomy pouch exactly. If you are already using a New Image 2-piece system, check the packaging of your current barrier or pouch for the flange size — it will be listed in inches (1-3/4", 2-1/4", or 2-3/4"). If you are setting up a new system, your ostomy nurse will measure your stoma and recommend the appropriate flange size based on your stoma diameter and the surrounding skin area. Do not mix flange sizes between barrier and pouch as this will prevent a secure seal.
Can I use the Coloplast Assura pouch with a Hollister barrier?
No — the Assura urostomy pouch is designed to couple with Assura 2-piece skin barriers from Coloplast only. Hollister and Coloplast use different coupling systems that are not cross-compatible. Mixing components from different manufacturers will result in an insecure connection and risk of leakage. Always pair pouches and barriers from the same product line and manufacturer. If you are considering switching brands, consult your ostomy nurse before purchasing to ensure you select a complete compatible system.
How often should a 2-piece urostomy barrier be changed?
Most 2-piece urostomy skin barriers are designed to be worn for 3 to 5 days before being replaced, though this varies by individual, skin condition, and the specific product used. The urostomy pouch is typically changed daily or every other day without removing the barrier. Always replace the barrier sooner if you notice lifting at the edges, leakage under the barrier, or skin irritation. Follow the wear time instructions included with your specific barrier, and consult your ostomy nurse if you are consistently experiencing shorter than expected wear times.
