How to properly clean and care for a Foley catheter. What are the steps for changing drainage bags. How to comfortably wear a Foley catheter and leg bag. What precautions should be taken when showering with a catheter.

Understanding Your Foley Catheter

A Foley catheter is a crucial medical device for many individuals requiring urinary assistance. But what exactly is it? A Foley catheter is a thin, flexible tube inserted through the urethra into the bladder to drain urine. It’s held in place by a small balloon filled with water, ensuring it stays securely positioned.

How Does a Foley Catheter Function?

The primary function of a Foley catheter is to facilitate urine drainage. As urine accumulates in the bladder, it flows through the catheter and into a drainage bag. This system allows for continuous urine elimination without the need for frequent bathroom visits.

• Urine flows from the bladder through the catheter
• A drainage tube connects the catheter to a collection bag
• The drainage bag is secured to the leg with special tape (Cath-Secure®)

There are two types of drainage bags you’ll become familiar with:

1. Leg bag: A smaller bag (0.5 liter capacity) worn during the day
2. Night bag: A larger bag (2 liter capacity) used while sleeping

Essential Care for Your Foley Catheter

Proper care of your Foley catheter is paramount to prevent complications and ensure your comfort. What are the key aspects of catheter care?

• Daily cleaning of the catheter
• Changing drainage bags twice daily
• Replacing drainage bags weekly or when clogged
• Daily washing of drainage bags
• Maintaining proper hydration

It’s normal to occasionally see small amounts of blood or urine around the catheter insertion site, especially during movement or bowel movements. However, if you notice this without urine draining into the bag, it’s crucial to contact your healthcare provider immediately.

Comfortable Wear and Positioning of Your Catheter

How can you ensure your Foley catheter and leg bag are worn comfortably? Here are some essential tips:

• Position the leg bag below your knee to facilitate drainage
• Secure the leg bag to your calf using provided Velcro® straps
• Use a leg strap to secure tubing to your thigh
• Ensure straps aren’t too tight to prevent circulation issues
• Apply water-based lubricant to prevent soreness
• Maintain cleanliness with daily showers

Showering with a Foley Catheter: Do’s and Don’ts

Can you shower with a Foley catheter? Absolutely! However, there are some important guidelines to follow:

• Always use the night bag when showering, as it’s waterproof
• Avoid bathing until the catheter is removed to prevent infections
• Consider showering in the morning before switching to the leg bag

Step-by-Step Guide to Cleaning Your Foley Catheter

Proper cleaning of your Foley catheter is crucial for preventing infections and ensuring its optimal function. What supplies do you need and what steps should you follow?

Supplies Needed:

• Mild soap (e.g., Dove®)
• Cath-Secure®
• Clean hands (washed with soap and water or sanitized)

Cleaning Steps:

1. Clean your hands thoroughly
2. Clean your genital area with mild soap and water
3. Clean the catheter insertion site (urethra)
4. Clean the catheter from the insertion point downward
5. Rinse and dry the area gently
6. Attach a new Cath-Secure® if needed

Drainage Bag Management: When and How to Change

Proper management of your drainage bags is essential for maintaining hygiene and preventing complications. How often should you change your drainage bags and what’s the correct procedure?

Changing Schedule:

• Morning: Switch from night bag to leg bag
• Evening: Switch from leg bag to night bag
• Weekly: Replace both bags with new ones

Changing Procedure:

1. Wash your hands thoroughly
2. Empty the current drainage bag
3. Disconnect the old bag from the catheter
4. Clean the catheter tip with an alcohol wipe
5. Connect the new bag to the catheter
6. Secure the new bag in place

Remember to change your drainage bag immediately if it becomes clogged or blocked, regardless of the regular changing schedule.

Hydration and Nutrition: Supporting Your Catheter Care

Proper hydration plays a crucial role in maintaining urinary health and ensuring your catheter functions optimally. How much should you drink and what foods can support your urinary health?

Hydration Guidelines:

• Aim to drink 1-2 glasses of fluid every 2 hours while awake
• Water is the best choice, but other clear fluids are also beneficial
• Monitor your urine color – pale yellow indicates good hydration

Nutrition for Urinary Health:

• Consume cranberry products to help prevent urinary tract infections
• Eat foods rich in vitamin C to support immune function
• Include probiotic-rich foods to maintain a healthy bacterial balance

While maintaining proper hydration is crucial, it’s important to consult with your healthcare provider about any specific fluid restrictions you may have due to other health conditions.

Recognizing and Preventing Complications

While Foley catheters are generally safe when properly maintained, it’s crucial to be aware of potential complications. What signs should you watch for and how can you prevent issues?

Signs of Potential Complications:

• Fever or chills
• Cloudy or strong-smelling urine

Remember, with proper care and management, a Foley catheter doesn’t have to significantly impact your quality of life. Many individuals lead active, fulfilling lives while using catheters.

When to Seek Medical Attention

While proper care can prevent many issues, it’s crucial to know when to seek medical help. What situations warrant immediate medical attention?

• No urine output for several hours
• Catheter becomes dislodged or falls out
• Persistent bleeding or large blood clots in urine
• Signs of infection (fever, chills, cloudy urine)
• Severe pain or discomfort
• Allergic reactions to catheter materials

Don’t hesitate to contact your healthcare provider if you’re unsure about any symptoms or have concerns about your catheter. It’s always better to err on the side of caution when it comes to your health.

Emotional Well-being and Catheter Use

Adapting to life with a Foley catheter can be challenging emotionally. How can you maintain a positive outlook and manage any anxiety or stress related to catheter use?

Coping Strategies:

• Educate yourself about your condition and catheter care
• Join support groups or online forums for individuals with catheters
• Practice relaxation techniques like deep breathing or meditation
• Maintain open communication with your healthcare team
• Focus on activities and hobbies you enjoy

Building Confidence:

1. Master your catheter care routine
2. Plan ahead for social situations
3. Remind yourself that many people successfully manage catheters
4. Celebrate small victories in your catheter management

Remember, it’s normal to have emotional ups and downs when adjusting to life with a catheter. Don’t hesitate to seek professional help if you’re struggling to cope.

Future Developments in Catheter Technology

The field of catheter technology is continually evolving. What innovations are on the horizon that could improve the experience of catheter users?

About Your Urinary (Foley) Catheter: How To Clean and Care for It

This information will help you care for your urinary (Foley) catheter.

Back to top

About your urinary (Foley) catheter

Your Foley catheter is a thin, flexible tube placed through your urethra (the small tube that carries urine from your bladder to outside your body) and into your bladder. Your Foley catheter drains your urine (pee). It’s held inside your bladder by a balloon filled with water.

How your Foley catheter works

Your urine goes from your bladder and through a drainage tube into a drainage collection bag. The drainage bag stays on your leg with a special tape called Cath-Secure^®.

You will have 2 types of drainage bags:

• A leg bag. This is the bag that you wear during the day. It holds half a liter of urine.
• A night bag. This is the bag you will put on at night before you go to bed. It holds 2 liters of urine.

The parts of the catheter that are outside your body are shown in Figure 1.

How to take care of your Foley catheter

To take care of your Foley catheter, you will need to:

• Clean your catheter every day.
• Change your drainage bags. You will change your drainage bag 2 times a day:
  • In the morning, change the night bag to the leg bag.
  • At night before you go to bed, change the leg bag to the night bag.
• Replace your drainage bags with new bags once a week. You should also change your drainage bag if it gets clogged or blocked.
• Wash your drainage bags every day.
• Drink 1 to 2 glasses of liquids every 2 hours while you’re awake to keep you hydrated.

You may see some blood or urine around where the catheter enters your body. This may happen when you’re walking or having a bowel movement (pooping). This is normal if there’s urine draining into the drainage bag. If you do not have urine draining into the drainage bag, call your healthcare provider.

How to comfortably wear your Foley catheter and leg bag

• The tubing from your leg bag should fit down to your calf with your leg slightly bent. If you have extra tubing, you may need to cut it. Your healthcare provider will show you how to do this.
• Always wear the leg bag below your knee. This will help it drain.
• Place the leg bag on your calf using the Velcro® straps your healthcare provider gave you. Use a leg strap to secure the tubing to your thigh.
• If the straps leave a mark on your leg, they are too tight. Loosen them. Leaving the straps too tight can lower your blood flow and cause blood clots.
• Use a water-based lubricant (such as Astroglide® or K-Y®) to keep your penis or vagina opening from getting sore.
• Keep your penis or vagina opening clean by taking a shower every day. This will help prevent infections when your Foley catheter is in place.

Back to top

How to shower with your Foley catheter

• You can shower while you have your catheter in place.
• Do not take a bath until your catheter is removed. Taking a bath while you have your catheter in place puts you at risk for infections.
• Make sure you always shower with your night bag. Your night bag is waterproof. Do not shower with your leg bag. Your leg bag has cloth on the side and will not dry as fast.
  • You may find it easier to shower in the morning before you change your night bag to your leg bag.

How to clean your Foley catheter

You can clean your catheter while you’re in the shower. Follow these instructions.

1. Gather your supplies. You will need:
   • Mild soap, such as Dove®.
   • 1 Cath-Secure®.
2. Clean your hands with soap and water or an alcohol-based hand sanitizer.
   • If you’re washing your hands with soap and water, wet your hands and apply soap. Rub your hands together well for at least 20 seconds, then rinse. Dry your hands with a paper towel. Use that same towel to turn off the faucet.
   • If you’re using an alcohol-based hand sanitizer, cover your hands with it. Rub them together until they’re dry.
3. Using mild soap and water, clean your penis or vagina.
   • If you have a penis, pull back your foreskin (the skin around the tip of your penis), if needed. Clean the area, including your penis.
   • If you have a vagina, separate your labia (the smaller folds of skin around your vaginal opening). Clean the area from front to back.
4. Clean the area where the catheter enters your body. This is called your urethra.
5. Clean the catheter from where it enters your body and then down, away from your body. Hold the catheter at the point it enters your body so that you do not put tension on it.
6. Rinse the area well and dry it gently.
7. If you removed your old Cath-Secure, attach the catheter to your leg with a new Cath-Secure. This will keep the catheter from moving.

How to take care of your drainage bags

Caring for your leg drainage bag

• Empty the leg bag into the toilet every 2 to 4 hours, as needed. You can do this through the spout at the bottom of the bag. Do not let the bag get completely full.
• Do not lie down for longer than 2 hours while you’re wearing the leg bag. This can keep your urine from draining the way it should.

Caring for your night drainage bag

• Always keep the night bag below the level of your bladder.
• When you go to sleep, hang your night bag off the bed. You can do this by using a small trash can. Place a clean plastic bag inside the trash can. Hang your night bag inside of the trash can.

Cleaning your drainage bags

Clean your leg bag and night bag every day. Follow these instructions.

1. Gather your supplies. You will need:
   • White vinegar.
   • Cool water.
2. Clean your hands with soap and water or an alcohol-based hand sanitizer.
   • If you’re washing your hands with soap and water, wet your hands and apply soap. Rub your hands together well for at least 20 seconds, then rinse. Dry your hands with a paper towel. Use that same towel to turn off the faucet.
   • If you’re using an alcohol-based hand sanitizer, cover your hands with it. Rub them together until they’re dry.
3. Rinse the bag with cool water. Do not use hot water because it can damage the plastic.
4. To help get rid of the smell, fill the bag halfway with a mixture of 1part white vinegar and 3 parts water. Shake the bag and let it sit for 15 minutes.
   • If you cannot get the mixture into the bag, try putting the vinegar and water into a measuring cup with a pour spout. Then use the spout to help pour the mixture into the bag.

What’s a Foley catheter? | Roswell Park Comprehensive Cancer Center

A Foley catheter is a semi-flexible plastic tube. One end is inserted into the bladder and the other end is attached to a bag that collects urine. It is used when you cannot urinate normally. This may be due to:

• Incontinence: You can’t control when you urinate.
• Urinary retention: Your bladder becomes full of urine and you (may) feel a desperate, urgent need to urinate, but you can’t. This is a concern because if urine remains in your bladder, you can develop a urinary tract infection. And although the bladder walls are muscular and can stretch, if they remain expanded for too long, the muscles will no longer be able to relax and you will not be able to urinate at all. Without relief, urinary retention can even lead to a bladder rupture.
• Urological or gynecological surgery that affects the bladder — for example, surgery involving the prostate, bladder, kidney or uterus.
• Anesthesia and opioid (narcotic) medications: These drugs can affect the nerves and muscles that control the bladder and urination, causing urinary retention and the need for catheterization. This happens more often in elderly patients. If you have had this problem in the past and you are being scheduled for surgery, be sure to let your doctors know.
• Medical conditions — for example, an enlarged prostate in men, a narrowing of the urethra (the tube that carries urine from the bladder to the outside of the body) and coma.
• Injuries — for example, spinal cord injuries.
• Input and output (I & O): Sometimes your clinical team needs to measure how much fluid you are taking in and how much fluid is going out. If you cannot use a commode with a collection/measuring device, collecting urine in a drainage bag provides an easy way to measure what is going out.

What to expect

People have mixed reactions to getting a urinary catheter. On one hand, while putting the catheter in place — or replacing it — may not be painful, it can be uncomfortable or embarrassing for some. On the other hand, urinary retention can be very painful, and inserting a catheter can provide great relief. If incontinence is the issue, a Foley can avoid problems that arise from having no control over your urination.

A Foley is considered a long-term or “indwelling” catheter because it can be left in place for a while. How long it will stay in place depends on your individual circumstances. Your physician will decide when to remove it or how often to change it. For example, if you are prone to catheter infections or blockages, it’s likely you’ll have the catheter replaced more frequently.

Catheters are among the most-used medical devices in hospitals. The most common complication with catheters is an infection called CAUTI (Catheter-Associated Urinary Tract Infection). The risk of developing CAUTI increases the longer a catheter is in place. To lower this risk, most catheters in hospitalized patients remain in place for only two to four days. After surgery, the catheter is removed as soon as you can urinate on your own.

What you can do

If you’re in the hospital, your nurses will care for your Foley catheter. If it’s left in place when you go home, follow the discharge and catheter care instructions you were given.

To help prevent infections and irritation or damage to the urethra and bladder:

• Wash your hands before and after handling any part of the Foley equipment.
• Drink six to eight glasses of water a day, unless you are on a fluid-restriction diet. Your urine should be clear or pale yellow.
• Clean the area where the catheter exits the body, and the catheter itself, with soap and water every day.
• Do not pull on, clamp, puncture or cut the catheter.
• While the catheter is in place, you may have bladder spasms, which can cause pain. Spasms are often set off by having a bowel movement. To help prevent spasms, use stool softeners to avoid constipation. Tell your doctor if you are having painful spasms. To lower risk of infection, clean the area well after having a bowel movement.
• Tell your doctor if you have any signs of infection, such as a fever of 100.4° F (38° C) or if urine is not draining into your bag. Your discharge instructions will specify when you should call the clinic.
• There are two types of collection bags — a large one that can be hung on a lower bedrail and a smaller one that can be strapped to your leg and hidden under clothing if you need to move around or go out. Both types of bags must be kept below the level of your bladder. This prevents urine from flowing back into the bladder and reduces the risk of infection. Empty the drainage bag when the bag is half full. DO NOT allow the urine to sit in the bag for more than three to four hours.

How is a Foley catheter put in place?

1) After explaining the procedure to you, a nurse will use a catheter kit to place your Foley.

2) The area around the urinary opening is cleansed. (The nurse may use an anesthetic gel to reduce any discomfort.)

3) The tip of the catheter is lubricated and inserted. Take deep breaths and try to relax.

4) The tip of the catheter, which is inside the bladder, has a small balloon at the end so the catheter won’t fall out. Once the catheter is in place, the nurse will inflate the balloon through a special port. (The balloon will be deflated just before the catheter is removed.)

5) The catheter is then connected to the drainage bag.

Keeping the catheter working properly and preventing infection are the most important things you can do. Follow the instructions provided by your nurses to stay safe and recover as quickly as possible.

How to choose a Foley catheter? Foley catheter and prostatic catheter are the main differences.

In today’s article we will tell you how to choose a Foley catheter, what you need to consider when buying, what types and structural features of urethral catheters, and how prostatic catheters differ from Foley catheters.

A Foley catheter or urethral catheter is a special medical device designed to drain urine from the bladder. To do this, it is introduced into the cavity of the bladder through natural ways – the urethra – and fixed with a balloon. Such a catheter is installed for a period of 1 to 90 days. Foley catheter is not uncommon in the Russian market. It can be ordered at a specialized company dealing with medical equipment and consumables, medical equipment stores, pharmacies, and some orthopedic salons. When buying a Foley catheter, do not forget to purchase a urinal – a special product that is attached to the Foley catheter, where urine enters after excretion from the body.

How to choose a Foley catheter?

To buy a Foley catheter, you need to clarify with your doctor the following parameters, knowledge of which will greatly facilitate your ordering a catheter:

Catheter size (diameter). The unit of measurement for the diameter of catheters is Sharière (Ch, Shr) or French (Fr). 1 Ch/Fr = 0.33 mm. The size of the catheter is chosen by the attending physician based on the patient’s condition, the time of installation, and the material of the catheter. As a rule, 6-10 Ch are children’s sizes, 14-16 Ch are more often for women, and 20-24 for men. Each case is unique, so never buy a Foley catheter without a doctor’s prescription. There are also various recommendations of professional urological associations – the Russian Society of Urology, the European Society of Urology – which detail the criteria for choosing a catheter diameter.

If the catheter is often clogged, you can choose a larger size. It must be remembered that the larger the diameter of the catheter, the higher the risk of injury to the urethra.

Another characteristic of the product associated with the size of the Foley catheter is the color coding. This helps doctors and nurses in the operating room or treatment room quickly find the right catheter based on its color, and not on the labels on the packaging or on the catheter itself. The color coding may vary from manufacturer to manufacturer, but it is usually universal and helps doctors navigate the range of consumables more easily. In the picture above you will see a red connector – this is the part in the Foley catheters that is color-coded. We see the red connector and understand that this catheter is 18 Ch.

Foley catheter length. Foley catheters can be male or female. This is due to anatomical features – the urethral canal in men is longer than in women. The length of the female Foley catheter is about 25 cm, the male catheter is 40-42 cm. The female Foley catheter is not available in all medical equipment stores and pharmacies, and besides, it cannot be used in men, so women and men are prescribed universal catheters 40 cm long.

Size balloon. To fix the catheter in the bladder cavity, a balloon is used, located at the distal end of the catheter. Upon insertion, the balloon is deflated and does not protrude above the catheter surface. With the successful introduction of the catheter into the bladder, the balloon is “inflated” with saline to the desired volume. Thanks to a special valve in the connector, saline does not flow back. Foley catheters most often have a balloon volume of 30 ml, but there are models with a balloon of 15 or 50 ml. In children’s Foley catheters, the volume of the balloon is 1.5-5 ml. The balloon prevents the urethral catheter from “falling out” of the bladder.

Foley catheter tip straight or curved or Nelaton vs Tiemann. The tip of the Foley catheter (the part above the balloon) can be straight or curved. The straight form (classic version) is the most common model. Such a tip is also called the Nelaton catheter, after the urologist who first used a urethral catheter to divert urine. For complicated cases of insertion, for example, with prostatic hyperplasia, there is a coracoid curved tip – the Tiemann catheter. The tip itself in Tiemann or Nelaton catheters is closed with two side holes.

Foley catheter material. The material of the catheter directly affects the comfort of the patient, the frequency of replacement of the catheter and its operational characteristics. Today, Foley catheters are made from:

• Silicone-coated latex (siliconized latex) is a cheap material, quite soft, porous. Unfortunately, many patients are allergic to latex, making long-term use impossible. To reduce the risk of allergies, as well as to improve performance, the latex catheter is coated with a micron layer of silicone. A latex Foley catheter is placed for up to 7 days.
• Silicone is a fully biocompatible material that does not cause inflammation or allergic reactions. Silicone catheters are soft, with a thin wall. Silicone Foley catheters have a large internal lumen, which provides better urine diversion. They clog less and can be installed for up to 30 days. Children’s catheters are made of silicone. The special treatment of the silicone and the surface of the catheter allowed them to be installed for up to 90 days – for example, the X-Tra and Folisyl LT series from Coloplast.
• “Silver” is an outdated type of catheter. Material: silicone with a layer of silver, so these catheters are often called “silver plated”. It was believed that silver catheters have antibacterial activity, however, studies have shown that the presence of a layer of silver does not significantly affect either the development of infection or the time of installation. Due to low profitability and lack of clear clinical efficacy, silver catheters are practically withdrawn from circulation. Instead, patients are advised to buy long-lasting silicone Foley catheters (with an insertion period of up to 90 days).

Number of strokes: 2 or 3? The most problematic issue. Unfortunately, due to errors in terminology, doctors, patients, and pharmacy staff often confuse three-way Foley catheters with prostatic catheters (TURP catheters, hemostatic catheters). The classic Foley catheter has 2 passages, that is, 2 channels, one of which is used for urine diversion, and the second for balloon inflation. In some cases, a third channel / passage is required – for washing and introducing medicinal substances into the bladder cavity.

However, there are prostatic or three-way catheters. Prostatic catheters are used exclusively in men after prostate surgery – resection of the prostate. Do not confuse them with Foley catheters. Despite the similar structure and function, both of these catheters differ. These differences are:

• Balloon volume: for prostatic catheters, the balloon has a volume of 50-120 ml to effectively prevent bleeding after prostate surgery (for Foley catheters it is 15-30 ml).
• Tip structure: prostatic catheters are divided into types Dufo, Delinot, Kuveler and others. The curved Dufour and straight Kuveler tips also have a large drainage hole for successful drainage of urine, blood clots, pieces of tissue and mucus. Below is a typical three-way Dufour catheter.

• Diameter: prostatic catheters size 18 to 24 Ch/Fr. Foley catheters have a much wider size range – from 6 to 30 Ch.
• Number of channels: prostatic catheters are usually always three-way.

Attention! This article is not a call for self-treatment! Be sure to consult with your doctor! Never insert and remove urethral catheters yourself!

Bottom line: any patient may be faced with the need to purchase Foley catheters. When choosing a catheter, it is important to know its dimensions, which are measured in Charrière / French, balloon volume, number of strokes. When buying, check all the data, be sure to check the expiration date of the medical product, the presence of the Registration Certificate and the Declaration and compliance, the availability of instructions. If you find it difficult to choose, then we recommend you the following positions:

Foley catheter: structure, materials, price, size

Pomerantsev’s Foley catheter has a wide range of applications. Used to divert urine, treat the urinary system, prepare for surgery, diagnose diseases, stimulate labor. For urinary disorders, Foley catheters are installed if long-term catheterization is necessary. Depending on the material, they can be used up to 90 days.

Foley catheter materials:

Often there are questions about which Foley catheter is better and why they have such different prices. Pricing depends primarily on the material of the catheter. The material affects the duration of use of the catheter.

Latex catheters. Foley latex catheter has great flexibility, elasticity, strength. Modern latex contains the minimum amount of proteins that can cause allergies. The catheters are also coated with silicone. This minimizes the risk of allergies. Latex catheters are used for catheterization up to 7 days. Latex catheters are cheaper than silicone ones.

Silicone catheters. Silicone biocompatible resistant material. Silicone prevents the deposition of salts on the inner opening of the catheter. Therefore, silicone catheters are used for catheterization up to 30 days. They are more expensive than latex.

Silver Foley catheters. There are also silver coated silicone catheters that can be used for 30 to 90 days. Silver prevents the growth of bacteria, the occurrence of urinary tract infections. Due to the high cost of production, the price of such catheters is higher.

For example, Foley Urethral Catheters, Silver Plated Foley Dover™ Medtronic (Unomedical)

Foley Catheter Design:

Foley catheters are available in 2-way and 3-way.

Two way channel has two ports. One to divert urine, the other to inflate the balloon.

Three-way catheter has a third port for drug administration, sampling, etc.

Adult catheters are available in 40 cm lengths and are a universal choice. Sometimes they are divided into male and female.

Women’s Foley catheters are shorter than men’s. After all, the female urethra is shorter than the male.

Male Foley Catheters are 40 cm long.

Pediatric Foley Catheters are thinner and shorter than adults. Sometimes they have additional design features for easier insertion into the child’s urethra.
