In medicine, a catheter /ˈkæθɪtər/ is a thin tube made from medical grade materials serving a broad range of functions. Catheters are medical devices that can be inserted in the body to treat diseases or perform a surgical procedure. By modifying the material or adjusting the way catheters are manufactured, it is possible to tailor catheters for cardiovascular, urological, gastrointestinal, neurovascular, and ophthalmic applications.
Catheters can be inserted into a body cavity, duct, or vessel. Functionally, they allow drainage, administration of fluids or gases, access by surgical instruments, and also perform a wide variety of other tasks depending on the type of catheter. The process of inserting a catheter is catheterization. In most uses, catheter is a thin, flexible tube ("soft" catheter) though catheters are available in varying levels of stiffness depending on the application. A catheter left inside the body, either temporarily or permanently, may be referred to as an indwelling catheter (for example, a peripherally inserted central catheter). A permanently inserted catheter may be referred to as a permcath (originally a trademark).
A Foley catheter is a flexible tube passed through the urethra and into the bladder to drain urine. It is the most common type of indwelling urinary catheter.
The tube of a Foley catheter has two separated channels, or lumens, running down its length. One lumen is open at both ends, and drains urine into a collection bag. The other lumen has a valve on the outside end and connects to a balloon at the tip. The balloon is inflated with sterile water when it lies inside the bladder to stop it from slipping out. Foley catheters are commonly made from silicone rubber or natural rubber.
Foley catheters should be used only when indicated, as use increases the risk of catheter-associated urinary tract infection and other adverse effects.
In an emergency department, indwelling urinary catheters are most commonly used to assist persons who cannot urinate. Indications for using a catheter include providing relief when there is urinary retention, monitoring urine output for critically ill persons, managing urination during surgery, and providing end-of-life care.

There are many different types of urinary catheters. This brief introduction gives a brief overview of the basic kinds of urinary catheters along with some images of each, then finishes off by explaining how catheter sizes are measured in French Units along with a conversion table. I hope this video is useful and informative. If you want more information, news, tips, and resources about urinary catheters, visit http://www.catheterguide.com.
