How do I choose a catheter size?
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 a Foley vs catheter?
An indwelling urinary catheter is inserted in the same way as an intermittent catheter, but the catheter is left in place. 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.
What is a 3 way catheter?

What size is Foley catheter?
They vary in size between 12 Fr (4 mm) and 30 Fr (10 mm). 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.
Which catheter is the most comfortable?
Determining Which Catheter is Best for You For some, a straight tip catheter will be more comfortable while others will prefer a coudé tip catheter.
What is the length of a female catheter?
There are three lengths: female (20–26cm), standard (40–45cm) and paediatric (30–31cm). Men should always receive standard catheters. If they receive a female-length catheter, the 'balloon' in the urethra can cause potentially serious complications, including haematuria, penile swelling or urinary retention.
What does FR mean in catheter?

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 ...

In addition to increased risk of UTIs, urinary catheters may produce allergic reactions.
What is a straight tip catheter?
A straight tip catheter is a catheter that is 100% straight, from one end to the next. Since they’re made with flexible materials, straight tip catheters can still move and bend, but without added pressure it stays straight. This is one of the most common types of catheters and come in a variety of lengths to accommodate differing lengths of the male and female urethra. People with an unobstructed pathway to the bladder will use a straight tip catheter. Straight tip catheters do not come pre-lubricated, so you will need to add an extra step to the insertion process.

An External Catheter Sizing Guide from Hollister is available to help with measurements.
Why do you put a drain bag lower than a catheter?
Drainage bags and lefs bags should be placed lower than the catheter to allow gravity to draw the urine away from the body and to prevent urine from draining back into the bladder. Make sure the bag is just the right size for your needs and that it works with your catheter.

Silicone coating: The silicone coating makes the catheter more secure and causes less allergies in the patient. The downside to silicone coating is that it makes the catheter less stretchable. Catheter eyes: Catheter eyes are the holes in which the urine drains through. The most commmon reason for a catheter to be replaced is the blockage ...
What is the cross sectional diameter of a urinary catheter?
The crosssectional diameter of a urinary catheter is equal to three times the diameter . Since urethral mucosa contains elastic tissue which will close around the catheter once inserted, the catheter chosen should be the smallest catheter that will adequately drain urine.
What is an IUC catheter?
Indwelling urinary catheters (IUCs) are semi-rigid, flexible tubes. They drain the bladder but block the urethra. IUCshave double lumens, or separate channels, running down it lengthwise. One of the lumen is open at both ends and allows for urine drainage by connection to a drainage bag.
Why do you need a bladder catheter?
This catheter is primarily used following urological surgery or in case of bleeding from a bladder or prostate tumor and the bladder may need continuous or intermittent irrigation to clear blood clots or debris. The catheter should have a smooth surface with two drainage eyes at the tip that allow for urine drainage.
What is the challenge of a catheter?

Where did the Foley catheter come from?
The name of the Foley catheter comes from the designer, Frederic Foley, a surgeon working in Boston, Massachusetts, in the 1930s. His original design was adopted by C. R. Bard, Inc. who manufactured the first prototypes and named them in honor of the surgeon.
Can a large diameter catheter cause stricture?
The routine use of large-size catheters diameters can cause more erosion of the bladder neck and urethral mucosa, can cause stricture formation, and do not allow adequate drainage of peri-urethral gland secretions, causing a buildup of secretions that may lead to irritation and infection.

Depending on the manufacturer and make, a catheter may have anywhere between one to four drainage eye lets, although most have one or two. The insertion tip goes into your urethra or stoma to drain the bladder.
What is hydrophilic catheter?
What sets this type of catheter apart is its special hydrophilic coating that acts as lubrication once activated by water. The coating is bonded to the surface of the catheter and becomes slippery when wet.
Why do hydrophilic catheters have a sterile water packet?
Most variations of hydrophilic catheters include a sterile water packet inside the catheter package that will burst easily with applied pressure. This soaks the catheter and activates its lubrication.
Why are closed system catheters touch free?
Closed system catheters are “touch-free,” because you never touch the catheter tube directly. 2. A soft, pre-lubricated cover known as an introducer tip helps the catheter get past the highest concentrations of bacteria as you insert it.
Why do we need a closed system catheter?
Because the system is completely integrated as one piece, you can self-cath anywhere you have privacy. Closed systems are a great option for reducing the risk of UTIs and bladder infections for a few reasons: 1. Closed system catheters are “touch-free,” because you never touch the catheter tube directly. 2.

Why is urinary catheterization important?
The human body needs to keep the bladder empty of fluids in order to avoid infection, keep your organs healthy, and prevent urine leakage. When the bladder isn’t able to empty itself, unnecessary stress is put on the kidneys, which can ultimately lead to kidney failure and sometimes irreversible damage.
