Uses, types, and what to expect

A urinary catheter is a flexible tube for draining urine from the bladder. It may be necessary for a person to use a urinary catheter if they have difficulty passing urine naturally.

This article outlines the different types of urinary catheter and provides advice on how to avoid side effects.

Share on PinterestA person may need a urinary catheter if they have an injury to the urethra, an enlarged prostate, or kidney stones.

A doctor may recommend a urinary catheter for a person who has difficulties when urinating. Reasons for needing a catheter can include:

• a blockage in the urethra, which is the tube that carries urine out of the bladder
• injury to the urethra
• an enlarged prostate in males
• birth defects affecting the urinary tract
• kidney, ureter, or bladder stones
• bladder weakness or nerve damage
• tumors within the urinary tract or reproductive organs

A healthcare provider may also insert a urinary catheter:

• to accurately measure urine output in critically ill people
• to drain the bladder before, during, or after a person has surgery
• during childbirth, to drain the women’s bladder after an epidural anesthetic
• to deliver medication directly into a person’s bladder
• for treating a person with urinary incontinence if other treatments have not been successful

The intermittent catheter, or a standard catheter, is a thin, flexible tube that a person temporarily inserts into their bladder through the urethra.

The external end of the tube may be left open, allowing the urine to drain into a receptacle. Another option is to attach the tube to an external drainage bag, which collects the urine.

What to expect

Once a person has emptied their bladder, they need to remove the catheter. It is necessary to remove the old catheter and insert a new one several times per day to empty the bladder.

A healthcare provider will teach the person how to do this correctly.

Side effects

Intermittent catheters are usually prelubricated to reduce discomfort during insertion.

Urinary tract infections (UTIs) are a common potential side effect of using an intermittent catheter. The risk of developing a UTI increases with longer-term use of the catheter.

According to Dr. Tomas L. Griebling, a professor of urology at the University of Kansas, intermittent catheters are less likely to cause infections than indwelling catheters.

Other possible side effects of using intermittent catheters include:

• Hematuria. This is the presence of red blood cells in the urine, which can cause the urine to appear red or brown. Hematuria is common when a person first starts using an intermittent catheter, but persistent hematuria may indicate a UTI.
• Bladder stones. These are common in people who use an intermittent catheter on a long-term basis.
• Urethral strictures. This is a narrowing of the urethra that can result from repeated trauma. People who insert their own intermittent catheters repeatedly over many months have a higher risk of urethral strictures.

Share on PinterestAn indwelling catheter will remain in place for days or weeks.

An indwelling catheter is similar to an intermittent catheter but remains in place for a period of days or weeks.

One end of the indwelling catheter has a deflated balloon attached. A healthcare provider will insert this end into the bladder and then inflate the balloon with sterile water to hold the catheter in place.

There are two main types of indwelling catheter, which have different insertion techniques:

• Urethral catheter. Also called a Foley catheter, the healthcare provider inserts this type through a person’s urethra.
• Suprapubic catheter. A doctor will surgically insert the suprapubic catheter through a small hole a few inches below the belly button. This operation will take place in the hospital while the person is under a local or a light general anesthetic.

What to expect

Indwelling catheters typically drain into a collection bag. A person can strap the bag to the inner thigh or attach it to a stand in a position lower than the bladder.

It is important to empty a drainage bag before it becomes full. For most people, this will mean emptying the bag every 2–4 hours. A person should also attach a clean, unused drainage bag twice per day and attach a larger bag at night.

Some indwelling catheters use a valve instead of a bag. Keeping the valve closed allows the bladder to fill up.

A person can then open the valve to empty their bladder and drain the urine out into a receptacle. Some people find this more convenient than using a drainage bag.

Side effects

Many people find suprapubic catheters more comfortable than urethral catheters. They are also less likely to cause an infection than a urethral catheter.

However, both types of indwelling catheter can cause the following side effects:

Bladder spasms

It is quite common for people with indwelling catheters to experience bladder spasms. This occurs when the bladder attempts to pass out the balloon section of the catheter. A doctor may prescribe medications to reduce the frequency and intensity of these spasms.

Blockages

People with an indwelling catheter may notice debris in the catheter tube. Though normal, these mineral deposits can sometimes block the catheter and prevent drainage.

It is essential for a person to notify a healthcare provider immediately if their catheter becomes blocked, or if they are passing blood clots or large pieces of debris.

Pain and discomfort

Long-term use of the indwelling catheter can cause pain and discomfort. It is important to discuss this with a doctor, who will be able to provide or advise on appropriate pain relief.

Some males have the option of using an external catheter. This is a condom-like device that fits over the penis. A tube attached to the catheter collects urine into a drainage bag.

Doctors usually recommend external catheters for males with incontinence who do not experience urinary blockages or retention and can use the catheter themselves.

What to expect

Because external catheters do not enter the urethra, they tend to cause very little discomfort. Compared with indwelling catheters, they are also less likely to cause a UTI.

Although external catheters for females do exist, they are rare in clinical settings due to concerns over their safety and effectiveness.

These catheters are generally poor at collecting urine and can cause damage to the surrounding skin and vaginal mucosa.

Side effects

External catheters are for short-term use only. Longer-term use increases the risk of:

• UTIs
• damage to the penis due to friction with the condom-like device
• a blockage in the urethra

Some people may find living with a catheter challenging and uncomfortable at first. However, as people become more accustomed to the catheter, they generally find that it has less impact on their daily lives.

This section provides tips on how to prevent and overcome some of the possible complications of catheter use.

Preventing infections

Share on PinterestSymptoms of a CAUTI can include a high temperature.

The main disadvantage of using a catheter is that it can allow certain bacteria to enter the body and cause infection.

According to the Centers for Disease Control and Prevention (CDC), urinary catheters are responsible for around 75 percent of UTIs that people acquire in the hospital. The risk of infection is highest when using an indwelling catheter.

Doctors refer to a UTI that results from catheter use as a catheter-associated UTI (CAUTI). Symptoms of a CAUTI can include:

• pain in the lower abdomen or groin area
• a high temperature
• a burning sensation during urination
• more frequent urination

A person can reduce their risk of developing a CAUTI by:

• washing their hands thoroughly with soap and warm water before and after touching catheter equipment
• keeping the skin around the catheter entrance clean by washing it with mild soap and water twice per day
• ensuring that urine collection bags are kept below the level of the bladder, as this will help prevent blockages
• not lying on the catheter, as this can prevent the flow of urine through the tube
• ensuring that there are no twists or kinks in the tubing, as blockages can raise the risk of infection
• keeping hydrated by drinking one or two glasses of liquid every 2 hours

Other activities

It is possible for a person using a urinary catheter to carry out most of their regular activities. A doctor will advise when it is safe for a person to resume working, exercising, or having sex.

Many people who use a catheter are concerned about the effect that it may have on their sex life. Generally, however, people with an intermittent or suprapubic catheter can have sex as normal. Those with a urethral catheter may find sex more difficult, but it is still possible.

Males who use an external catheter can usually remove the sheath during sex or place a standard condom over the top of it. In some cases, it is possible to temporarily remove the tube and drainage bag.

People who use a drainage bag with their catheter may wish to talk to their healthcare provider about the possibility of switching to a valve system. This can make sex easier and more comfortable.

A urinary catheter is an important aid for people who have difficulty passing urine. There are several different types available, and a person should talk to their doctor about the type that is best suited to their needs.

A common complication of using any type of catheter is an increased risk of UTIs. However, a person can reduce this risk by practicing good personal hygiene and catheter care, as well as learning how to use the equipment correctly.

People should consider talking to a medical professional if they experience any persistent pain or discomfort associated with the catheter. They can offer advice on how to make living with a catheter more comfortable.

design, types, indications for use and precautions

Foley catheter is an indispensable device used in medical urological practice. Consider the main indications for use, varieties, materials and other features of the product.

What is a Foley catheter

Urological Foley catheter is a special medical device designed to drain urine from the bladder in patients who cannot empty themselves. The device allows you to effectively organize the removal of urine without injuring the patient, without violating his comfort.

The device is a flexible tube with an inflatable cuff at the distal end to prevent involuntary release of the device from the bladder. Due to this design, the Foley catheter is also used to stimulate the cervix during labor (when indicated).

Indications and contraindications for use

The list of indications for the use of the urinary Foley catheter is very wide:

• pathologies accompanied by narrowing of the ureter;
• the appearance of neoplasms around the ureter, leading to its compression;
• inflammatory or other pathological processes within or on the walls of the lumen;
• malignant neoplasms involving or adjacent to the genitourinary system;
• prostate adenoma;
• cicatricial formations after traumatic injuries;
• swelling of the walls of the ureter with subsequent narrowing;
• involuntary urination, lack of conscious control over the process in the patient;
• state of coma;
• narcotic sleep during surgery;
• preparation of the cervix for childbirth;
• other conditions and pathologies in which the patient cannot empty the bladder on his own.

There are also contraindications. Each case is considered individually, the doctor weighs the potential risks and possible complications of using the product. Foley catheter is not used for:

• acute urethritis, including gonorrheal type;
• injuries of the bladder, urethral canal;
• contracted sphincter;
• Urinary sphincter spasms.

Foley catheter materials

Urological Foley catheter is available in various materials. Let’s consider each option in more detail.

Silicone coated latex

Quite soft, porous and the cheapest material. Patients are often allergic to latex, so these Foley catheters are not suitable for long-term use. Modern products are coated with a micron layer of silicone to improve performance.

Silicone

Biocompatible material that does not cause inflammation or allergic reactions. Suitable for long term use. Silicone Foley catheters have thin walls and a large internal lumen, which provides high patency and good urine diversion. Baby tubes are also made from silicone.

“Silver”

Obsolete look, almost out of service. Previously, it was thought that coating silicone tubes with a thin layer of silver gives an additional antibacterial effect. But studies have shown that the presence of silver does not significantly affect the properties of the catheter.

Types of Foley catheters

Structurally, the product is divided into two types: two-way and three-way. Let’s take a look at the features of each.

2-way

Classic 2-way Foley catheter. One is needed to divert urine, the second – to inflate the balloon.

Three-way

Three-way device: for diverting urine, inflating the balloon and injecting drugs into the bladder cavity.

Foley catheters 9 highlights0005

The range of urological Foley catheters is very large. Products differ in many parameters and indicators.

Bottle size

Standard bottle size is 30ml, but 15ml, 50ml models are available. In children’s products, the indicator varies from 1.5 to 5 ml.

Tip construction

The tip of the catheter can be:

• Straight. The most common option, which is also called the Nelaton catheter. It is used for uncomplicated cases of problems with the urethral canal.
• Curved. Tiemann catheter, which is used in complicated cases of insertion.

Diameter

The patency of the catheter directly depends on this indicator. The unit of measurement is Charrière (Ch). The appropriate size of the device can only be determined by the doctor, taking into account the current state of health of the patient.

There are generally accepted recommendations regarding the choice of catheter diameter:

• 6-8 Ch – Pediatric;
• 10 Ch – urine is clear, without foreign inclusions;
• 12-14 Ch – urine is clear, without hematuria;
• Foley catheter 16 Ch – cloudy urine, the presence of small clots, mucus, tissue debris;
• Foley catheter 18 Ch – clots and mucus in the urine, severe hematuria;
• Foley catheter 20-24 Ch – severe hematuria, flushing required.

Number of channels

Two and three channel devices are available. The first are classic, designed to divert urine. The latter, in addition to the function of emptying the bladder, are suitable for supplying drugs and solutions to the organ.

How to choose a Foley catheter

To buy a suitable Foley catheter in Moscow or another city in Russia, you need to carefully choose the product. Pay attention to such aspects:

• Length. Male Foley catheters are standardly longer than female catheters – 40 versus 25 cm. But not all pharmacies have a female version of the product, so the size of 40 cm is considered universal.
• Balloon size. The standard volume is 30 ml, but depending on the age, gender of the patient, existing diseases, as well as the purpose of using the device, the indicator may differ.
• Tip. Straight – for standard cases, curved – for complicated ones.
• Material. The best option is hypoallergenic silicone, which is well accepted by the body and does not cause inflammation.
• Diam. Only a doctor can correctly determine the appropriate diameter of the catheter.
• Number of channels. Standard catheters are two-way. Three-way are used when adjuvant therapy is required, or as prostatic catheters.

Silver Coated Foley Catheter Helps Prevent Urinary Tract Infections – critical-care

SilverCoat Foley Catheter (photo courtesy of COVALON).

The innovative Foley catheter continuously releases lubricant during use and helps reduce the chance of catheter-related urinary tract infection (CAUTI).

SilverCoat Foley Catheter is made of 100% silicone and has a permanent lubrication coating impregnated with silver ions. The silver is held in the hydrophilic coating by ionic bonding, which in turn is covalently bonded to the silicone surface of the catheter through a patented surface modification technology. Thus, the coating provides a protective zone of bacterial inhibition that surrounds the surface of the catheter and counteracts the penetration of colonies of microorganisms, reducing the likelihood of CAUTI.

A Foley catheter is a thin, sterile tube inserted into the bladder to drain urine; because it sometimes needs to be in place for a long period of time, it is also called an indwelling catheter. Retention of the catheter is achieved with a distal balloon filled with sterile water to prevent accidental withdrawal. Urine is drained through the catheter tube into a bag, which empties when filled. The SilverCoat Silicone Foley Catheter is a product of Covalon (Mississauga, Canada) and has been approved in the US by the US Food and Drug Administration (FDA).

“We believe our patented technology, which is incorporated into the SilverCoat Foley catheter, provides superior protection for patients at risk of developing CAUTI,” says Brian Pedlar, CEO of Covalon. 25% of patients annually, and over 500,000 patients with indwelling catheters develop an infection.
