Types of urinary catheters – NHS

There are several different types of urinary catheter, which are inserted and used in different ways.

Intermittent urinary catheters

In most cases, intermittent urinary catheters are recommended. These catheters are inserted several times a day, for just long enough to drain your bladder, and then removed.

You should be taught how to insert the catheter yourself. It’s usually inserted into your bladder through the urethra (the tube that carries urine out of your body).

The sterile catheter is usually pre-lubricated, to reduce the risk of any discomfort when you insert it.

One end of the catheter is either left open-ended, to allow drainage into a toilet, or attached to a bag to collect the urine. The other end is guided through your urethra until it enters your bladder and urine starts to flow.

When the flow of urine stops, the catheter can be removed. A new catheter is used each time.

Indwelling urinary catheters

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.

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.

Indwelling catheters are sometimes fitted with a valve. The valve can be opened to allow urine to be drained into a toilet, and closed to allow the bladder to fill with urine until drainage is convenient.

Most indwelling catheters need to be changed at least every 3 months.

Suprapubic catheters

A suprapubic catheter is a type of catheter that is left in place. 

Rather than being inserted through your urethra, the catheter is inserted through a hole in your tummy (abdomen) and then directly into your bladder. This procedure can be done under general anaesthetic, epidural anaesthetic or local anaesthetic.

A suprapubic catheter is used when the urethra is damaged or blocked, or when someone is unable to use an intermittent catheter.

The catheter may be secured to the side of your body and attached to a collection bag strapped to your leg. Alternatively, a valve can be attached that opens to allow urine to be drained into a toilet, and closes to allow the bladder to fill with urine until drainage is convenient.

This type of catheter is usually changed every 4 to 12 weeks.

Urinary catheters: MedlinePlus Medical Encyclopedia

A urinary catheter is a tube placed in the body to drain and collect urine from the bladder.

Urinary catheters are used to drain the bladder. Your health care provider may recommend that you use a catheter if you have:

• Urinary incontinence (leaking urine or being unable to control when you urinate)
• Urinary retention (being unable to empty your bladder when you need to)
• Surgery on the prostate or genitals
• Other medical conditions such as multiple sclerosis, spinal cord injury, dementia, or other operations

Catheters come in many sizes, materials (latex, silicone, Teflon), and types (straight or coude tip). A Foley catheter is a common type of indwelling catheter. It has soft, plastic or rubber tube that is inserted into the bladder to drain the urine.

In most cases, your provider will use the smallest catheter that is appropriate.

There are 3 main types of catheters:

• Indwelling catheter
• Condom catheter
• Intermittent self-catheter

INDWELLING URETHRAL CATHETERS

An indwelling urinary catheter is one that is left in the bladder. You may use an indwelling catheter for a short time or a long time.

An indwelling catheter collects urine by attaching to a drainage bag. The bag has a valve that can be opened to allow urine to flow out. Some of these bags can be secured to your leg. This allows you to wear the bag under your clothes. An indwelling catheter may be inserted into the bladder in 2 ways:

• Most often, the catheter is inserted through the urethra. This is the tube that carries urine from the bladder to the outside of the body.
• Sometimes, the provider will insert a catheter into your bladder through a small hole in your lower belly. This is done at a hospital or provider’s office.

An indwelling catheter has a small balloon inflated on the end of it. This prevents the catheter from sliding out of your body. When the catheter needs to be removed, the balloon is deflated.

CONDOM CATHETERS

Condom catheters can be used by men with incontinence. There is no tube placed inside the penis. Instead, a condom-like device is placed over the penis. A tube leads from this device to a drainage bag. The condom catheter must be changed every day.

INTERMITTENT CATHETERS

You would use an intermittent catheter when you only need to use a catheter sometimes or you do not want to wear a bag. You or your caregiver will insert the catheter to drain the bladder and then remove it. This can be done only once or several times a day. The frequency will depend on the reason you need to use this method or how much urine needs to be drained from the bladder.

DRAINAGE BAGS

A catheter is most often attached to a drainage bag.

Keep the drainage bag lower than your bladder so that urine does not flow back up into your bladder. Empty the drainage device when it is about one half full and at bedtime. Always wash your hands with soap and water before emptying the bag.

HOW TO CARE FOR A CATHETER

To care for an indwelling catheter, clean the area where the catheter exits your body and the catheter itself with soap and water every day. Also clean the area after every bowel movement to prevent infection.

If you have a suprapubic catheter, clean the opening in your belly and the tube with soap and water every day. Then cover it with dry gauze.

Drink plenty of fluids to help prevent infections. Ask your provider how much you should drink.

Wash your hands before and after handling the drainage device. DO NOT allow the outlet valve to touch anything. If the outlet gets dirty, clean it with soap and water.

Sometimes urine can leak around the catheter. This may be caused by:

• A catheter that is blocked or that has a kink in it
• A catheter that is too small in diameter
• Bladder spasms
• Constipation
• The wrong balloon size
• Urinary tract infections

POSSIBLE COMPLICATIONS

Complications of catheter use include:

• Allergy or sensitivity to latex
• Bladder stones
• Blood infections (septicemia)
• Blood in the urine (hematuria)
• Kidney damage (usually only with long-term, indwelling catheter use)
• Urethral injury
• Urinary tract or kidney infections
• Bladder cancer (only after long-term indwelling catheter)

Contact your provider if you have:

• Bladder spasms that do not go away
• Bleeding into or around the catheter
• Fever or chills
• Large amounts of urine leaking around the catheter
• Skin sores around a suprapubic catheter
• Stones or sediment in the urinary catheter or drainage bag
• Swelling of the urethra around the catheter
• Urine with a strong smell, or that is thick or cloudy
• Very little or no urine draining from the catheter and you are drinking enough fluids

If the catheter becomes clogged, painful, or infected, it will need to be replaced right away.

How to insert a Foley catheter?

Foley catheter is a type of urinal that differs in the form of a retaining inflatable balloon. The equipment was named in memory of the American urologist Frederick Foley and is actively used:

• for the removal of urinary fluid;
• drug withdrawal;
• in X-ray studies;
• in obstetrics;
• in traumatology.

Widespread in medicine due to increased sterility, and large lateral holes provide strong drainage. The device is considered safe for insertion into the bladder due to the high patency through the urethra – suitable for a short or long period.

Indications for catheter insertion

Bladder drainage is a common procedure in urological clinics. The process is presented in the form of introducing a special tube – a catheter – into the bladder. It is used for diagnostic or prophylactic purposes. The use of a Foley catheter to drain the urethra is recommended by doctors if the following symptoms appear:

• urinary retention;
• kidney problems;
• inflammation inside the bladder;
• diagnosis of the amount of residual urine;
• administration of drugs into the urethra;
• operations using anesthesia or standard anesthesia.

If you have at least one of the above symptoms, you should contact your doctor for advice to provide timely assistance to the body!

Types of Foley catheters

When buying a Foley catheter, you should pay attention to the material from which it is made. Depending on the components of the urinal, short-term or long-term drainage will be carried out in the absence of the ability to empty the bladder on their own. Foley catheters are divided into two main types, divided by size into men’s, women’s and children’s.

1. Latex catheters

When using a latex Foley catheter for more than 30 days, inflammatory or allergic processes are formed. Latex devices with a hydrophilic coating are less traumatic and, upon contact with the water surface, become smooth and slippery – this makes it possible to drain the urethra painlessly.

Main parameters of latex catheters:

• high strength;
• high level of elasticity;
• anti-deformation.

2. Silicone catheters

Despite the large number of advantages, the main disadvantage is the high cost due to the difficulties in production. Silicone catheters have the following characteristics:

• human biocompatible component – silicone;
• high temperature resistance;
• is intended for long-term catheterization, up to 12 weeks;
• does not cause allergies due to the biological compatibility of silicone with humans;
• absence of saline encrustations (formation of blockages) in the catheter;
• slow growth of bacteria due to silicone material.

The forerunner of silicone catheters is considered to be silver-plated, made of silicone with a layer of silver.

Detailed Instructions for Foley Catheter Insertion

Attention! Only a physician should insert the catheter for safety and ease of insertion. Detailed instructions are given below and are suitable for inserting the catheter into the urethra for both men and women:

1. Thoroughly clean the vulva, then insert the disposable catheter into the bladder.
2. Next, attach the special funnel to the connecting tube of the equipment.
3. Make sure the catheter is secure and fill the balloon with the recommended amount of sterile water.
4. Drugs can be administered using an additional port in a 3-way Foley catheter.
5. Check the flow of urinary fluid into the balloon.
6. Do not pinch or twist the outside of the device.
7. If overfilled, remove fluid and install new bottle.

Detailed Instructions for Foley Catheter Removal

To remove a Foley catheter, patients are advised to go to the hospital to see their doctor. Removal of drainage from the bladder requires the use of local anesthesia and the insertion of a cystoscope. Inside the urinary canal, the free end of the tube is captured by a special tool – a maniple, after which the Foley catheter is removed from the human body. The operation is performed manually inside a sterile cabinet.

Complications after a catheter that require a doctor’s consultation

If the following symptoms appear after the catheter is removed, the patient should immediately contact the doctor to eliminate the problem:

• bloody discharge in the urine;
• bleeding from the vulva;
• burning in the intimate area;
• fever;
• onset of fever;
• specific smell of urine.

How often should a Foley catheter be changed?

• Silicone catheter can be used up to 30 days;
• Latex catheter used up to 7 days;
• Silver plated is an obsolete type of catheter and is used up to 3 months.

How to care for the catheter?

With proper use of the Foley catheter, cleansing is not required and occurs naturally. To enhance the cleansing properties, patients are given cranberry juice, berries and herbal decoctions in the diet. Flushing required after:

• appearance of salts on the walls;
• turbidity of the urinary fluid;
• clogging of the lumen of the urine output tube.

The fluid is drained every 3-4 hours – this is how long it takes to completely fill the balloon. Urinary fluid is drained from a reusable urinal and washed with antiseptics for subsequent use, and a disposable one is disposed of and replaced with a new sterile balloon.

How do I clean my catheter at home?

For rinsing, use a solution of “Dioxydin” in proportions of 1:40 with water or tablets “Furacillin” 0.1 milligram per 100 milliliters of water. You can rinse with a ready-made remedy from a pharmacy, which the doctor will prescribe for the patient.

Instructions for proper cleaning of the catheter:

1. Wash your hands and remove the syringe, draw up the solution.
2. Disconnect the urinal, treat the ends of the tube with antiseptic solutions.
3. Insert the syringe and slowly dispense the solution.
4. First pour 20-30 milliliters of solution, after draining repeat the previous steps three times.
5. Attach the urinal back to the balloon.

Consult a doctor to clean the catheter yourself.

How do I shower with a catheter?

• you can take a standard shower with a night bag;
• it is not recommended to take a shower with the device attached to the leg in order to avoid complications;
• It is strictly forbidden to take a bath with a urinal installed, wait until the Foley catheter is removed, otherwise you risk infection.

Conclusion

Foley catheter is an effective medical device for the treatment of diseases of the urethra and drainage of urinary fluid. Modern catheters do not cause discomfort, are easy to maintain and are sterile. An additional advantage is a wide range of models in terms of size and service life, which greatly simplifies the work for patients or medical professionals.

About the urinary catheter (Foley)

A Foley catheter is a thin, flexible tube that is placed through the urethra (the small tube that carries urine out of the bladder) into the bladder. The Foley catheter drains your urine. It is held inside the bladder with a balloon filled with water.

How the Foley catheter works

Urine exits the bladder into the bag through a drainage tube. The urinal is attached to the leg with a special patch Cath-Secure ^® .

You will have 2 types of urinals:

• Foot urinal. This is a urinal that you wear during the day. It holds half a liter of urine.
• Night urinal. You will wear this urinal in the evening before going to bed. It holds 2 liters of urine.

Parts of the catheter outside your body are shown in Figure 1.

How to care for your Foley catheter

Caring for your Foley catheter:

• flush the catheter daily;
• change urinals; you must do this 2 times a day:
  • In the morning, replace your night bag with a foot bag.
  • At night, before going to bed, replace the foot bag with a night bag.
• Change urinals to new ones once a week; you should also change the urinal if it is clogged or clogged;
• flush urinals daily;
• Drink 1-2 glasses of fluid every 2 hours while you are awake to stay hydrated.

There may be traces of blood or urine around the insertion site of the catheter. This can happen while walking or having a bowel movement. It is normal if urine continues to pass into the urinal. If urine does not come into the bag, call your health care provider.

How to make your Foley catheter and leg bag comfortable to wear

• The tube on the foot urinal should reach to the lower leg with a slightly bent leg. If the tube is too long, you will need to cut it. Your healthcare provider will show you how to do this.
• The foot urinal must be secured below the knee. This will encourage the flow of urine into it.
• Attach the leg bag to your lower leg with the Velcro® straps provided by your healthcare provider. Attach the tube to your thigh using the strap.
• If the straps leave marks on your leg, then they are too tight. Relax them. Tight straps can reduce blood flow and lead to blood clots.
• Apply a water-based lubricant (such as Astroglide® or K-Y®) to the penis or vaginal opening.
• Shower daily to keep your penis or vaginal opening clean. This will help prevent infections when using a Foley catheter.

How to shower with a Foley catheter in place

• You can shower while your catheter is in place.
• Do not take a bath until the catheter is removed. Bathing with a catheter in place puts you at risk of infection.
• Always shower with a night bag. It is waterproof. Do not shower with a foot bag. The fabric on the side of such a urinal will not dry quickly.
  • You may find it easier to shower in the morning before changing from a night bag to a leg bag.

How to clean your Foley catheter

You can clean your catheter while in the shower. Follow these instructions:

1. Prepare everything you need. You will need:
   • Mild soap such as Dove®.
   • 1 Cath-Secure® patch.
2. Wash your hands with soap and water or an alcohol-based hand sanitizer.
   • If you wash your hands with soap, wet them and lather. Rub thoroughly for at least 20 seconds, then rinse. Dry your hands with a paper towel. Turn off the faucet with the same towel.
   • If using an alcohol-based hand sanitizer, apply it to your hands. Rub your hands together until it dries completely.
3. Wash your penis or vagina with mild soap and water.
   • If you have your foreskin (the skin around the glans penis) spared, move it back. Then wash the area and the penis itself.
   • Separate the labia (small folds of skin around the vaginal opening) from the vagina. Then rinse this area from front to back.
4. Clean the area where the catheter enters your body. This is the urethra.
5. When cleaning the catheter, make movements from the place of its introduction into the body and down, away from the catheter. Hold the catheter at the site of its introduction into the body so that it does not stretch.
6. Rinse your perineum well and pat it dry gently.
7. If you removed the old Cath-Secure patch, attach the catheter to your leg with a new Cath-Secure patch. This will prevent displacement of the catheter.

How to care for urinals

Caring for a portable foot bag

• Empty your foot bag into the toilet every 2 to 4 hours as needed. This can be done through the drain hole at the bottom of the urinal. Do not allow the urinal to fill completely.
• Do not lie down for more than 2 hours while you are using the foot bag. This may interfere with the flow of urine.

Night bag care

• The night urinal should always be below the level of the bladder.
• When you go to bed, hang your night bag on your bed. You can use a small trash can for this. Put a clean plastic bag in the wastebasket. Hang a night bag on the inside of the basket.

Cleaning the urinals

Clean the foot and night bags daily. Follow these instructions:

1. Prepare everything you need. You will need:
   • white vinegar;
   • cold water.
2. Wash your hands with soap and water or an alcohol-based hand sanitizer.
   • If you wash your hands with soap, wet them and lather. Rub thoroughly for at least 20 seconds, then rinse. Dry your hands with a paper towel. Turn off the faucet with the same towel.
   • If using an alcohol-based hand sanitizer, apply it to your hands. Rub your hands together until it dries completely.
3. Rinse the urinal with cold water. Do not use hot water as it may damage the plastic parts.
4. To get rid of the smell, fill the bag halfway with a mixture of 1 part white vinegar and 3 parts water. Shake the bag and soak it in this mixture for 15 minutes.
   • If you are unable to fill the bag with the mixture, pour it into a measuring cup with a spout, then pour from the glass into a urinal.
5. Rinse the urinal with cold water. Hang it up to dry.
