What is a French Foley catheter?
Foley catheters are sized according to their outside diameter using the French scale. One French (Fr) equals 0.33mm. They vary in size between 12 Fr (4 mm) and 30 Fr (10 mm).
Is a 16 or 18 French Foley bigger?
Size 14 french: green. Size 16 french: orange. Size 18 french: red.
Is a French catheter the same as a Foley?
Foley Catheter Sizes The relative size of a Foley catheter is described using French units (Fr). In general, urinary catheters range in size from 8Fr to 36Fr in diameter. 1 Fr is equivalent to 0.33 mm = . 013" = 1/77" in diameter.
Why is it called a French catheter?
Charriere's French scale was used to describe the external diameter of a catheter. Thus the term “French (Fr)” size was coined. Joseph-Frederic-Benoit Charriere was a 19th century Parisian maker of surgical instruments. A 12 French catheter is approximately 4 mm in external diameter (0.33 mm = 1 French [Fr]).
How do I choose the right size catheter?
To determine the size of a urinary catheter, simply multiply the diameter length in millimeters by 3. For example, if the catheter has a diameter of 4.7 mm, it will have an FR size of 14. Most catheters with funnels utilize a universal-coding system to determine the sizing.
What is the average catheter size for females?

What is the difference between a straight catheter and a Foley catheter?
Once the bladder is empty, the catheter is carefully removed and thrown away. Unlike Foley catheters, straight catheters do not attach to collection bags, which means that they need to be used in a bathroom or other place where urine may be properly disposed.
What is the difference between gauge and French?
By convention, needles or single lumen catheters are sized by gauge and multi-lumen catheters are measured by French size. Whereas French size and diameter are related directly, gauge and size are related inversely; a lower gauge indicates a greater diameter.

What is a Foley catheter?
Straight Catheters. A Foley is a urinary catheter that is meant to be in place for a period of time. The Foley catheter should not be confused with a straight catheter, which is inserted once and discarded after the bladder has been emptied. 1 .
Where is the Foley catheter inserted?
Overview. The Foley catheter is inserted into the urethra, the tube that carries urine out of the body. It is gently pushed up the urethra until it reaches the bladder. A hole in the bladder end of the tube allows urine to flow out of the bladder, through the urethra and out of the body into the collection bag.
How long does a urinary catheter stay in?
An indwelling urinary catheter is intended to stay in place for an extended period of time, ranging from hours to weeks. In some patients, the catheter stays in even longer, but this is rare. Most hospitals have programs and policies that require catheters to be removed as soon as possible to reduce the risk of infection occurring. 2

Why is a catheter coated with a sterile lubricant?
The catheter is coated with a sterile lubricant to make insertion easier and to avoid irritating the inside of the urethra. Sterile technique is used to help prevent urinary tract infections (UTIs), the most common complication associated with urinary catheter use.
What is the French size of a catheter?
The French size is a measure of the outer diameter of a catheter (not internal drainage channel, or inner diameter ). So, for example, if a two-way catheter of 20 Fr is compared to a 20 Fr three-way catheter, they both have the same external diameter but the two-way catheter will have a larger drainage channel than the three-way.
How to find the diameter of a round catheter?
A round catheter of 1 French has an external diameter of 1⁄3 mm, and therefore the diameter of a round catheter in millimetres can be determined by dividing the French size by 3: For example, if the French size is 9, the diameter is 9/3 = 3.0; mm. It is seen that the French unit is fully redundant with the metric system ...
What is the French scale used for?
Unsourced material may be challenged and removed. The French scale or French gauge system is commonly used to measure the size of a catheter.

However, simply gauge, G or GA generally refers ...
How to tell the French size?
The French size is three times the diameter in millimeters. Thus, the French size is roughly equivalent to the circumference of a circular catheter; the true circumference being slightly larger (circumference = diameter * π where π is approximately 3.14).
What is the gauge system for Foley catheters?
All internal urinary catheters, including Foley catheters and intermittent catheters, are sized by a universal gauge system. This gauge system is known as a French size, which is based upon a measurement of the external diameter of the catheter tube.
How to find the French size of a catheter?
The French size of a catheter is determined by a simple multiplication of 3 (diameters in millimeters multiplied by 3 = the French size). For example, if a catheter has a diameter of 4.7 millimeters, then the French (Fr) size is 14.
How long is a pediatric catheter?
Pediatric length catheters are typically around 10 inches long. The smallest pediatric catheter French sizes (5 or 6 French) are typically for babies and infants. Children and adolescents typically use pediatric catheters between 8 to 12 French. Here are just a few of the many pediatric catheters for babies and children that we offer at 180 Medical.
Why is determining the French size of a catheter important?
Why is determining the French size such an important part of selecting the right catheter for your needs? Efficiency and comfort are both important elements in the self-catheterization process. If you use a urinary catheter with too large of a diameter for your urethra, insertion can feel difficult or cause friction. Catheterization may even feel painful if you’re using a catheter that’s too big. Also, if it’s far too large, you will not be able to insert it at all.
What size catheter do women use?

Can you use a catheter that is too big?
Catheterization may even feel painful if you’re using a catheter that’s too big. Also, if it’s far too large, you will not be able to insert it at all. On the other hand, if you use a French size that is too small, you may find the pace of urine drainage is very slow.
Can a French size catheter escape urine?
In addition, if you use a catheter French size that’s much smaller than your urethra, urine may escape around the catheter tube. This can be messy, and it’ll be harder to control the flow. Luckily, catheters are made in a vast range of French sizes to suit all kinds of bodies.
How to clean a catheter?
Clean your catheter area and anal opening after every bowel movement. For men: Use a soapy cloth to clean the tip of your penis. Start where the catheter enters. Wipe backward making sure to pull back the foreskin. Then use a cloth with clear water in the same direction to clean away the soap.
How to secure a catheter tube to your body?

Specialty Foley Catheters
A “specialty” Foley catheter is determined by the materials it is made of, tip configuration, number of lumens or channels, and the size of the balloon.
Overview
Types
Foley catheters come in several types:
• Coudé (French for elbowed) catheters have a 45° bend at the tip that facilitates easier passage through an enlarged prostate.
• Councill tip catheters have a small hole at the tip so they can be passed over a wire.
History
The name comes from the designer, Frederic Foley, a surgeon who worked in Boston, Massachusetts in the 1930s. His original design was adopted by C. R. Bard, Inc. of Murray Hill, New Jersey, who manufactured the first prototypes and named them in honor of the surgeon.
Sizes
The relative size of a Foley catheter is described using French units (F). . Alternatively, the size of a 10 F catheter might be expressed as 10Ch (Charriere units - named after a 19th century French scientific instrument maker, Joseph-Frédéric-Benoît Charrière).The most common sizes are 10 F to 28 F. 1 F is equivalent to 0.33 mm = .013" = 1/77" of diameter. Foley catheters are usually color coded by size with a solid color band at the external end of the balloon inflation tube, allowing fo…
Medical uses
Indwelling urinary catheters are most commonly used to assist people who cannot urinate on their own. 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.
Foley catheters are used during the following situations:
Contraindications
Indwelling urinary catheters should not be used to monitor stable people who are able to urinate or for the convenience of the patient or hospital staff. Urethral trauma is the only absolute contraindication to the placement of a urinary catheter. Examination findings such as blood at the urethral meatus, or a high riding prostate necessitate a retrograde urethrogram prior to insertion.
In the United States, catheter-associated urinary tract infection is the most common type of hosp…
Adverse effects
All catheterised bladders become colonised with bacteria within 24 hours. This is not an infection and is very poorly understood by clinicians. Whilst the presence of a catheter does increase the incidence of bloodstream infections secondary to a urinary origin, there is a huge amount of unnecessary, and likely harmful, antimicrobial prescribing on the basis of detection of asymptomatic bacteriuria. The industry is moving to silver-coated catheters in an attempt to red…
