Hydrophilic catheters have a smooth, slippery surface which is designed to make intermittent self-catheterization, known as “cathing”, easier and help reduce the risk of infection. This is created by a hydrophilic substance on the catheter surface, which binds with water to the surface, resulting in a smooth and slippery catheter, helping to make insertion and removal easier. This type of catheter will include a sterile water or saline solution, which may be present in the package itself or in a separate packet. If the catheter has a packet, you must first release, or burst, the packet to activate the hydrophilic properties of the catheter.
