With SenSura 1-piece urostomy, the SenSura double-layer barrier is permanently attached to the pouch. To change the pouch, the whole appliance is removed and replaced at once. SenSura 1-piece urostomy is available with flat or convex barriers. The full line includes transparent and opaque pouches with barriers that are pre-cut (already cut to size) or "cut-to-fit" (meaning they can be cut to achieve a custom fit). Features: Protection layer - protects the skin from stoma output. Skin care layer - keeps skin healthy by absorbing excess moisture. Anti-reflux valve - prevents the urine from washing over the stoma, reducing the risk of urinary infections. Soft tuck-away outlet - easy to use and can be tucked away when not in use. This prevents it from rubbing on your leg, offering more comfort and discretion. Multi-chambers - the pouch has been divided into chambers which spread the urine evenly within the pouch. This allows it to have a flat and discreet profile.
