This ostomy system is a comprehensive product line with our latest skin barrier technologies. The plastic coupling ring allows the pouch and skin barrier to snap together for audible security. People living with a urostomy have unique needs, which is why ConvaTec offers a pouch product line especially for them. Non-sterile unit dose kits contain one barrier and one pouch. Available with standard wear skin barrier and drainable pouch or with extended wear skin barrier and a urostomy pouch.
