What is catheter size measured in?
That “Fr” is the unit of measurement for the French Scale measurement system, and it's responsible for how catheters are sized. Commonly referred to as simply “French size,” the French Scale system is how all modern catheters are measured.
What is a standard Foley catheter?
The catheter is held in the bladder by a water-filled balloon, which prevents it falling out. These types of catheters are often known as Foley catheters. Urine is drained through a tube connected to a collection bag, which can either be strapped to the inside of your leg or attached to a stand on the floor.
What size foley catheter is commonly used for adults?
Size 12 Fr is large enough to relieve urinary obstruction in most adults, although practitioners typically choose size 14 to 16 Fr for initial catheterization. Larger diameter catheters may be required for adequate drainage of hematuria or clots.

They are used by people who are unable to drain out the urinary bladder on their own either because of a surgery, urinary incontinence and enlarged prostrate or other medical reasons.
Why is the catheter smaller than the urethra?
If the catheter is smaller than the urethra then there will be leakage of urine. However, one must keep in mind that if there is the chance of blood clots passing through the catheter or large volumes of fluid flow, following an infection or postoperative bleeding, then the catheter should be slightly larger.
Why is it important to get the right size catheter?
It is important to get the catheter sizing right. The reason is three-fold. If the FR is smaller than what is needed, then the emptying out of the bladder will take time. If the FR is too big for the urethra, then there will be difficulty and pain when inserting the catheter. A catheter size larger than required is more likely to cause trauma ...
What size is a FR 14?

How does Foley catheter work?
A Foley catheter can also be used to ripen the cervix during induction of labor. When used for this purpose, the procedure is called extra-amniotic saline infusion. In this procedure, the balloon is inserted behind the cervical wall and inflated, for example with 30-80 mL of saline. The remaining length of the catheter is pulled slightly taut and taped to the inside of the woman's leg. The inflated balloon applies pressure to the cervix as the baby's head would prior to labor, causing it to dilate. As the cervix dilates over time, the catheter is readjusted to again be slightly taut and retaped to maintain pressure. When the cervix has dilated sufficiently, the catheter drops out.
Why are Foley catheters silver coated?
The industry is moving to silver-coated catheters in an attempt to reduce the incidence of urinary tract infections , although there is limited evidence of efficacy. An additional problem is that Foley catheters tend to become coated over time with a biofilm that can obstruct the drainage.

The urethra begins to bleed. The healthcare provider monitors the bleeding. Catheterization introduces an infection into the bladder. The risk of bladder or urinary tract infection increases with the number of days the catheter is in place.
What is the size of a Foley catheter?
The standard French sizing system for Foley catheters ranges from the smallest size – 5 Fr – to the largest – 24 Fr . You can easily convert a millimeter measurement to French sizing by multiplying the diameter in millimeters by 3. For example, an 8 mm-diameter Foley catheter is a French size 24.

How does Foley catheter work?
How Do Foley Catheters Work? The Foley catheter uses gravity to drain the bladder of urine. First, a medical technician threads the balloon end of the sterile, flexible tube through the urethra, which channels urine under normal circumstances. The urethra provides a direct path to the bladder.
When was the Foley catheter invented?
Frederic Foley invented the Foley catheter in 1928, and this medical instrument is still the most common urinary catheter in use today. For patients who are having trouble urinating after surgery, are comatose or have loss of bladder control, Foley catheters provide drainage and relief.

What is the best catheter material for urethral drainage?
Choose the catheter material that best suits your body and minimizes the chances of developing urethral irritation. Plastic or PVC catheter usually has a large diameter and helps in providing good postoperative drainage. Hydrogel coated latex catheter is known to be compatible with body tissues.
Why is it important to choose the right size balloon for a catheter?
Choice of the balloon size should be made wisely because if the balloon is too large or too small, it can result into bladder complications. Larger balloons can drag the catheter due to the weight of water contained in them. They also sit higher in the bladder, resulting in urethral damage.
How does a Foley catheter work?
A Foley catheter is passed through the urethra and into the bladder. The tube has two separated channels, or lumens, running down its length. One lumen is open at both ends, and allows urine to drain out 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 ...

What size balloon is used for Foley catheter?
Balloon: Foley catheter comes with 3 balloon sizes: 5cc, 10cc and 30cc.

Overview
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…

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.
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…
