There are three main types of intermittent urologic catheters available to choose from including closed system catheters, hydrophilic catheters, and intermittent uncoated catheters. Each type of catheter has different options like the type of material the catheter is made of, the length of the catheter, French size, catheter tip, and more. Some of the different options are detailed below.
Closed System Catheters
Closed system catheters are pre-lubricated catheters that are self-contained, allowing for a sterile environment. It includes an introducer tip that allows the catheter to bypass the highest concentrations of bacteria located in the first few millimeters of the urethra, significantly reducing the risk of infection. Closed system catheters have an attached collection bag which allows for discreet cathing where facilities are not available and also has the ability to measure output.
Hydrophilic (Self-Lubricated) Catheters
Hydrophilic catheters are coated with a hydrophilic polymer that becomes very slippery when wet to promote excellent gliding properties and provides up to 95 percent lower friction when compared to other catheters. The result is a much more comfortable insertion.
Straight catheters are a straight tube of flexible plastic or rubber. One end has a rounded tip, and the other end typically has a funnel end. Intermittent catheters can also come in coudé tip, latex, silicone, red rubber, and antibacterial.
