What Is a Foley Catheter?

The Foley catheter is an indwelling catheter for urinary retention.

The Foley catheter is a thin, flexible tubes used to pass urine from the bladder. Like other indwelling catheters, Foley catheters are designed to remain in the bladder for a longer period of time. Created by Frederic Foley in 1929, the Foley catheter is currently the most popular type of indwelling catheter used. 

How a Foley Catheter Works

Foley catheters are inserted through the urethra and up into the bladder. Small openings in the tip, called eyelets, allow urine to flow through the catheter into the collection bag.

To keep the Foley catheter in place, sterile water is injected through a second channel in the catheter. This water inflates the balloon, preventing the catheter from falling out.

In most cases, Foley catheters remain in the urethra for a month at a time. This makes them easier to manage, but  also comes with a slightly higher risk of infections such as a urinary tract infection (UTI).

Parts of a Foley Catheter

There are four  basic parts that make up most straight catheters: 


Foley catheter tubing

Flexible, hollow tubing usually made of latex that allows the flow of urine.


Foley catheter balloon.

A small inflatable balloon at the tip of the catheter that can be inflated or deflated with sterile water.


Foley catheter port

Small latches that connect the catheter to a collection bag and inflate the balloon at the tip.

Drainage Bag

Foley catheter drainage bag

A leak-proof pouch that attaches to the catheter and collects urine as it exits the body. Collection bags come in a variety of different styles and sizes.

Styles of Foley Catheters

Foley catheters come in various styles and deisgns. Here are a few of the most common ones:

two-way Foley catheter

The standard type of Foley catheter. They have two ports: one for the flow of urine and one for inflating the balloon.

three way Foley catheter

Three-Way Foley catheter

Who Uses a Foley Catheter?

Foley catheters are prescribed for men and women who cannot use a catheter themselves, or who have mobility issues that would prevent them from being able to use an intermittent catheter. Common situations requiring a Foley could include quadriplegia, being bedridden, or mental impairments.


Insurance Coverage of Foley Catheters

Foley Catheters are covered by most insurance plans, including Medicaid, Medicare, and private insurance. Each insurance plan has its own rules and requirements for coverage, but every plan will require a prescription from a doctor.

The number of Foley catheters you can receive depends on your insurance and the doctor’s instructions.
