Hydrophilic Catheters: An Evidence-Based Analysis

The objective of this analysis was to review the evidence on the effectiveness of hydrophilic catheters for patients requiring intermittent catheterization. Hydrophilic catheters have a polymer coating that binds o the surface of the catheter. When the polymer coating is submersed in water, it absorbs and binds the water to the catheter. The catheter surface becomes smooth and very slippery. This slippery surface remains intact upon insertion into the urethra and maintains lubrication through the length of the urethra. The hydrophilic coating is designed to reduce the friction, as the catheter is inserted with the intention of reducing the risk of urethral damage. It has been suggested that because the hydrophilic catheters do not require manual lubrication they are more sterile and thus less likely to cause infection. Most hydrophilic catheters are prepackaged in sterile water, or there is a pouch of sterile water that is broken and released into the catheter package when the catheter is ready to use.
