Understanding Urinary Catheters: Purpose and Types

A urinary catheter is a crucial medical device used in various healthcare settings. It’s a hollow, flexible tube inserted through the urethra into the bladder to drain urine into an external collection bag. These catheters are often referred to as ‘indwelling’ or ‘long-term’ catheters due to their nature of placement.

Why are urinary catheters used? They serve several important purposes:

• Assist with urinary incontinence
• Help manage urinary retention
• Aid patients who are unable to use the toilet independently

Once inserted, a small balloon on the internal end is inflated with sterile water to keep the catheter in place. This ensures continuous drainage and prevents the catheter from slipping out.

Preparation for Male Urinary Catheter Insertion: Essential Steps

Proper preparation is crucial for a successful and safe catheter insertion. Here are the key steps to follow:

1. Gather all necessary equipment
2. Discuss the procedure with the patient
3. Obtain informed consent
4. Check current medications and known allergies
5. Ensure adequate lighting and privacy
6. Position the patient correctly

How should the patient be positioned for catheter insertion? The patient should lie on their back with slightly flexed knees and feet slightly apart. This position provides optimal access for the healthcare provider and comfort for the patient.

Equipment Checklist for Catheterization

• Catheterization pack
• Sterile catheter (100% silicone for latex-allergic patients)
• Cleansing solution
• Sterile water for balloon inflation
• Anaesthetic gel
• Sterile gloves
• Fenestrated drape
• Waterproof sheet
• Specimen container (if needed)

The Male Catheterization Procedure: Step-by-Step Guide

The catheterization procedure requires precision and adherence to strict hygiene protocols. Here’s a detailed breakdown of the steps:

1. Perform hand hygiene and prepare a sterile field
2. Cleanse the genital area
3. Apply anaesthetic gel
4. Insert the catheter
5. Inflate the balloon
6. Connect to drainage system
7. Secure the catheter

How is the catheter correctly inserted? Hold the penis behind the glans and raise it to a 90-degree angle to the body. Insert the catheter until resistance is felt at the external urethral sphincter muscle. Then gently continue until the ‘Y’ of the catheter tube is at the urethral opening, ensuring the balloon has passed the prostate.

Overcoming Insertion Challenges

Sometimes, resistance may be encountered during insertion. In such cases:

• Apply gentle, steady pressure
• Ask the patient to take a deep breath, cough, or bear down
• Gently rotate the catheter
• Consider using additional lubricant

Is it normal to feel resistance during catheter insertion? Some resistance at the urethral sphincter is normal, but persistent resistance may require additional techniques or reassessment of the procedure.

Ensuring Patient Comfort and Safety During Catheterization

Patient comfort and safety are paramount during the catheterization process. Here are some key considerations:

• Maintain patient privacy throughout the procedure
• Use adequate anaesthetic gel to minimize discomfort
• Communicate clearly with the patient at each step
• Monitor for signs of pain or discomfort
• Ensure proper catheter placement before inflating the balloon

How can you tell if the catheter is correctly placed? Urine should flow freely into the drainage bag. If there’s no urine flow or the patient experiences pain, do not inflate the balloon as this could indicate incorrect placement.

Post-Insertion Care and Maintenance

After successful catheter insertion, proper care is essential to prevent complications:

1. Secure the catheter to prevent movement and potential injury
2. Keep the genital area clean and dry
3. Monitor urine output and catheter function regularly
4. Educate the patient on catheter care and potential signs of complications

How often should a catheter be changed? The frequency of catheter changes depends on the type of catheter and individual patient factors. Generally, silicone catheters can remain in place for up to 12 weeks, while latex catheters typically need changing every 2-4 weeks.

Potential Complications and How to Avoid Them

While urinary catheterization is a common procedure, it’s not without risks. Potential complications include:

• Urinary tract infections
• Bladder spasms
• Catheter blockage
• Urethral trauma
• Balloon inflation in the prostatic urethra

How can these complications be prevented? Strict adherence to aseptic technique, proper insertion procedure, regular monitoring, and timely catheter changes are key to minimizing risks.

Recognizing and Managing Complications

Early recognition of complications is crucial. Signs to watch for include:

• Pain or discomfort
• Fever or chills
• Cloudy or bloody urine
• Decreased or no urine output

If any of these signs occur, prompt medical evaluation is necessary.

Best Practices for Healthcare Providers Performing Catheterization

To ensure optimal outcomes, healthcare providers should adhere to these best practices:

1. Stay updated on current catheterization guidelines
2. Practice proper hand hygiene
3. Use sterile technique throughout the procedure
4. Communicate effectively with patients
5. Document the procedure thoroughly
6. Monitor for complications and address them promptly

How can healthcare providers improve their catheterization skills? Regular training, staying informed about new techniques and technologies, and participating in skill assessments can help maintain and improve proficiency in catheterization procedures.

Patient Education: Empowering Males with Urinary Catheters

Educating patients is a crucial aspect of catheter care. Patients should be informed about:

• Basic catheter function and care
• Signs of potential complications
• Proper hygiene practices
• Activity restrictions and limitations
• When to seek medical help

How can patients effectively manage their catheters at home? Proper hand hygiene, regular cleaning of the genital area, maintaining good hydration, and following healthcare provider instructions are key to successful catheter management at home.

Addressing Common Patient Concerns

Patients often have concerns about living with a catheter. Common questions include:

• Can I shower with a catheter?
• How will the catheter affect my daily activities?
• What should I do if the catheter becomes dislodged?
• How can I prevent urinary tract infections?

Addressing these concerns can help alleviate anxiety and improve patient compliance with catheter care.

Urinary catheter insertion in male patients is a complex procedure that requires skill, attention to detail, and a thorough understanding of male anatomy. By following proper techniques, maintaining strict hygiene, and prioritizing patient comfort and safety, healthcare providers can ensure successful catheterization and minimize the risk of complications. Ongoing education for both healthcare providers and patients is essential for optimal catheter management and improved quality of life for those requiring long-term catheterization.

Transcript

Hi there! Let’s take a look at urinary catheters and catheter insertion for male patients.

A urinary catheter (also known as an ‘indwelling’ or ‘long-term’ catheter) is a hollow, flexible tube inserted through the urethra into the bladder to drain urine into an external collection bag.

Once the catheter has been inserted, a small balloon on the internal end is inflated with sterile water to keep it in situ.

Catheters are used often in healthcare settings to assist with a variety of conditions, such as both urinary incontinence and urinary retention, or by patients who may be unable to go to the toilet without assistance.

Procedure

The following demonstration is based on the Catheterisation Clinical Guidelines by the Australia and New Zealand Urological Nurses Society.

Remember to always refer first to your organisation’s internal policies and procedures when performing any procedure like this one.

• To start, gather all equipment required for the procedure.
• Discuss the procedure with the client. Consider using other educational resources such as brochures or interpreters if needed.
• Obtain the client’s consent.
• Check current medications and any known allergies.
• If the client has a latex allergy, a 100% silicone catheter is needed for this procedure.
• Ensure adequate lighting.
• Maintain the client’s privacy by using means such as hospital screens or bed curtains. Ensure the client is warm and not exposed.
• Have the client lie in their bed on their back.
• Ask the client to slightly flex their knees, with their feet slightly apart.
• Place a waterproof sheet under the client’s buttocks.
• Perform hand hygiene.
• Prepare and sanitise the trolley or a clean surface.
• Using an aseptic technique, open the catheterisation pack, and add sterile equipment such as the catheter.
• Pour cleansing solution onto tray.
• If a specimen is needed, open the specimen container at this time.
• Empty sterile water (which may be included in the package) into tray in preparation for balloon inflation.
• Take covering off the client.
• Perform hand hygiene, and don non-sterile gloves.
• Pull the foreskin back if needed. Cleanse the glans penis with cleansing solution using a circular motion from the penile meatus to the base of the penis.
• Remove non-sterile gloves, perform hand hygiene and don sterile gloves.
• Put the fenestrated drape on the client.
• Apply anaesthetic gel to the catheter length.
• Prepare a syringe to inflate the balloon with by drawing up sterile water into the syringe.
• Advise the client that there is a risk of stinging from the anaesthetic gel.
• With a piece of gauze, hold the penis and apply gel to the meatus, then introduce the remaining gel into the urethra.
• Discard the gel container.
• Hold the penis behind the glans and raise the penis to a 90-degree angle to the body.
• Insert the catheter until resistance is felt at the external urethral sphincter muscle.
• Then gently continue until the ‘Y’ of the catheter tube is at the urethral opening to ensure that the balloon is passed the prostate.
• If the balloon is inflated in the prostatic urethra, this will cause pain and urethral trauma.
• If resistance at the urethral sphincter muscles persists, apply gentle, steady pressure on the catheter and advise the client to take a deep breath, cough or bear down, and/or try to pass urine.
• Gently rotate the catheter and consider using a second tube of lubricant if resistance persists.
• Once inserted successfully, slowly inflate the balloon per manufacturer instructions.
• Do not inflate if the client complains of pain or urine is not flowing freely, as this could indicate incorrect catheter placement or bladder spasm.
• Once correctly inflated, pull on the catheter slightly until resistance is felt.
• Connect the catheter to a drainage system or compatible valve.
• Secure the catheter in place using tape or a catheter strap.
• Leave some slack to ensure that the catheter does not become taut when the client moves to reduce the risk of injury.
• Ensure the glans penis is kept clean and dry to avoid skin irritations or infections.
• Reposition foreskin if necessary.
• Remove gloves and perform hand hygiene.
• Check in regularly to ensure the client is comfortable.
• Dispose of used equipment and gloves in a biohazard bag, and clinical waste bag in an appropriate waste system.
• Remember to maintain hand hygiene and complete any relevant documentation.

• Place all equipment within easy reach on an uncontaminated sterile field on a bedside tray. You may put the box containing the catheter and the drainage system between the patient’s legs, so that it is easily accessible during the procedure.

• If not done already, attach the catheter to the collecting system and do not break the seal unless a different type or size of catheter or irrigation of the catheter is required.

• Test the retention balloon for integrity by inflating it with water, and apply lubricant to the catheter tip.

• Saturate the applicator swabs, cotton balls, or gauze with povidone iodine.

• Place the sterile fenestrated drape over the pelvis so that the penis remains exposed.

• Grasp the shaft of the penis using your nondominant hand, and retract the foreskin if the patient is uncircumcised. This hand is now nonsterile and must not be removed from the penis or touch any of the equipment during the rest of the procedure.

• Cleanse the glans penis with applicator swabs, gauze, or cotton balls saturated in povidone iodine. Use a circular motion, beginning at the meatus, and work your way outward. Discard or set aside the newly contaminated items.

• Inject viscous lidocaine into the urethra. Insert the hub of the lidocaine-containing syringe into the penile meatus and inject about 5 mL. Pinch the meatus closed, to retain the lidocaine within the urethra, for at least 1 minute. The lidocaine distends the urethra, as well as provides some anesthesia, thereby easing catheter passage.

• Hold the catheter in your free hand. If a coudé catheter is being used, the tip should point upward, so as to track the superior urethral wall during insertion.

• Advance the catheter slowly through the urethra and into the urinary bladder. Patient discomfort is common. Ask the patient to relax and take slow deep breaths as you continue to apply steady pressure on the catheter until it is fully advanced to the level of the side port. Urine should flow freely into the collection tubing.

• Slowly inflate the balloon with 5 to 10 mL of water. Obvious resistance or patient discomfort suggests incorrect placement. If this happens, deflate the balloon, withdraw the catheter slightly, and then reinsert the catheter all the way before trying to reinflate the balloon.

• Position the balloon at the bladder neck, after successful balloon inflation, by slowly withdrawing the catheter until you feel resistance.

• Remove the drapes.

• Secure the catheter to the thigh with an adhesive bandage, tape, or strap. Some advocate taping the catheter to the lower abdominal wall to minimize pressure on the posterior urethra.

• Place the bag below the level of the patient to ensure that urine can drain via gravity.

• Be sure to maintain strict sterile technique during the procedure to avoid urinary tract infection Introduction to Urinary Tract Infections (UTIs) Urinary tract infections (UTIs) can be divided into upper tract infections, which involve the kidneys ( pyelonephritis), and lower tract infections, which involve the bladder ( cystitis), urethra… read more .

• Be sure to reduce the foreskin after the procedure.

• Be careful not to use excessive force during insertion, which could potentially cause urethral injury.

• Do not continue attempts at catheter placement if significant resistance is met or if the catheter feels to be buckling inside the urethra and not advancing.

• Urine will appear in the catheter before the balloon has advanced beyond the prostate. Continue advancing the catheter completely to the end of the catheter before inflating the balloon, to avoid inflating the balloon in the prostate or urethral lumen, which will cause significant bleeding.

• If the catheter appears to be in the correct position, but urine does not return, lubricant may be obstructing drainage of urine. Flush the catheter with normal saline to dislodge the lubricant and see if urine returns.

• If the balloon is difficult to inflate or the balloon port distends during inflation, the proximal end of the catheter is probably not in the correct position. Deflate the balloon and advance the catheter further into the bladder.

• If correct positioning is questioned, flush the catheter with 30 to 60 mL of normal saline. If the fluid can be flushed and aspirated easily, then the catheter is in the correct position. A catheter that will not irrigate is not in proper position.

• Consult a urologist for any questions regarding catheter size and style or difficulty placing a catheter.

Bladder catheterization: necessary preparation, course of the surgeon’s appointment and contraindications

Normally, the urinary tract is sterile, and in order to avoid infectious complications, sterility must be observed. Only sterile catheters are inserted. The doctor or nurse puts on sterile gloves. The head of the penis and the foreskin of men, the vulva with the external opening of the urethra in women are treated with furatsilin or other antiseptic solution, also sterile.

The patient (or patient) lies on his back, bending and spreading his legs. The nurse or doctor stands on the right, with his left hand exposes the head of the penis or pushes the labia apart. Sterile tweezers are taken in the right hand. These tweezers capture the catheter closer to the rounded end. In order for the catheter to move smoothly along the urethra and not injure it, the end of the catheter is moistened with a solution of petroleum jelly, which must also be sterile.

Then insert the end of the catheter into the opening of the urethra. Slowly continue insertion, intercepting the catheter with forceps until it is in bladder . Evidence of this will be the release of urine from the outer end of the catheter.

If catheterization is simultaneous, remove the catheter immediately after passing urine. Before extraction, a solution of furacilin is often injected into the lumen of the bladder with a syringe. With prolonged drainage of the bladder, the catheter is fixed with adhesive plaster to the inner surface of the thigh, lengthened by means of tubes and adapters, and connected to a container for collecting urine. In this case, special attention should be paid to asepsis. The catheter is essentially a foreign body, and its prolonged presence can provoke an infectious inflammation.

Since the urinary system of men and women has significant differences, the technique of bladder catheterization in both sexes will also be different. The urethra of women is short, so in order to release urine, it is enough to advance the catheter to a depth of about 5-10 cm. But at the same time, you need to make sure that the end of the catheter enters the opening of the urethra and does not slip into the vagina. In general, the catheterization technique for women is easier than for men.

In men, the urethra is much longer, and therefore the depth of catheter advancement is greater, and is about 20-25 cm. There are physiological constrictions and bends here, which make it somewhat difficult to advance the catheter. Significant difficulties can also be with strictures that develop as a result of inflammatory cicatricial changes in the urethra. An enlarged prostate interferes with the catheter’s progress.

Relatively long urethra with physiological and pathological obstacles creates preconditions for injuries. Therefore, in the event of obstacles, in no case should force be used. In these cases, re-catheterization is resorted to with more rigid or thin products of a different modification. In special cases, the urologist uses metal catheters. If catheterization is fundamentally impossible, they decide on the imposition of an epicystostomy, an opening communicating with the bladder on the anterior abdominal wall.

Despite the apparent ease of the procedure, it is by no means trusted to be performed by the patient on his own, nor are untrained persons involved in the installation of the catheter. Firstly, only a specialist knows about all the stages of installing a catheter, follows the rules of antisepsis, uses petroleum jelly or a special gel for gentle administration, and checks the tightness of the device with a syringe. Also, a nurse or urologist knows how to properly advance the catheter, follows the rules of asepsis. In men, the penis is held in a position perpendicular to the body during insertion and advancement of the catheter. The room itself, in which the catheter is installed, must meet the standards of sterility, so the introduction at home is carried out only in case of emergency.

If a catheter is to be inserted for a long time, then the general condition of the patient also needs to be monitored. The catheter should be emptied of accumulated urine every 8 hours.

If a patient tries to introduce a catheter on his own without proper knowledge and skills, then there is a high probability of damage to the urethra, which will lead to an inflammatory process and the need for treatment. Another likely option is the introduction of an infection, which can also lead to the development of an inflammatory process with the need for therapy under medical supervision.

Once the urine collection bag is in place, the patient or medical staff monitors the progress of the outflow. If the catheter fills with urine earlier than 8 hours, it is emptied. Getting rid of the accumulated urine is carried out before the complete filling of the catheter, as this can disrupt the flow of urine and lead to undesirable consequences. If the progress of the accumulation of urine in the catheter is monitored and full filling is not allowed, the insertion of the catheter is still a safe procedure without any negative consequences.

The specialist also ensures that the place of collection of urine is below the location of the bladder in a person. As a rule, for this it is attached at the hip, fixed and monitored for fullness. The recommended time to empty the device of accumulated urine is when the level is about half full. The patient can empty himself, having received prior instructions from the medical staff on how to do it correctly, and in no case removes the catheter on his own during the emptying procedure.

It is believed that it is easier for patients to insert a catheter than for patients. The reason is not only the greater length of the urethra in men, but also narrowing and expansion, which require sufficient sensitivity and skill from medical personnel when inserting a catheter. In addition, catheters are not only single-channel, but also multi-channel, up to 3. This allows you to enter any drugs directly into the bladder without disturbing the process of urine outflow through another channel.

Catheterization can be used for various diseases, operations and procedures. For example, this is required by an operation to increase the penis in men, therapy during inflammatory processes in the urogenital area. Catheterization is used in all cases of obstructed outflow of urine.

A properly placed catheter does not increase the risk of inflammatory processes and is not a cause of infectious diseases of the urogenital area. Catheterization can be carried out for women, men and children at any age if necessary and at the discretion of the doctor. If performed correctly, catheterization is a painless and safe option for diverting urine in an emergency.

Bladder catheterization in case of pathological obstruction of the outflow of urine, as well as for diagnostic purposes, involves the use of a catheter in the form of a thin tube into the urethra.

Indications for catheterization

For therapeutic purposes, the installation of a urinary catheter is carried out in the following conditions:

• acute urinary retention;
• the presence of blood clots, mucus and pus in the bladder;
• administration of chemotherapeutic agents;
• after operations to restore the patency of the urethra.

Catheterization is also used for diagnostic purposes.

1. Urine sampling for analysis can be done with a Nelaton urological catheter (it is a thin plastic tube).
2. Ultrasound diagnosis of the pelvic organs should be performed on a full bladder. Catheterization is used if, due to voluntary urination or other pathological conditions, the patient cannot fill it on his own.
3. In case of severe poisoning or comatose conditions of the patient, when it is necessary to control the daily volume of urine (diuresis).

The installation of soft catheters is carried out by paramedical staff: a nurse and a paramedic – catheterization with a rigid catheter is performed by a doctor.

Contraindications

These conditions are considered an absolute contraindication for elective catheterizations:

• acute bacterial infections of the prostate;
• damage to the urethral canal;
• narrowing of the urethra.

In urgent cases, insertion of the catheter with extreme caution is possible.

Features of the catheterization procedure in men

It is more difficult to place a urinary catheter in a man due to the peculiarities of physiology (long curved urethra).

To place a Nelaton or Foley catheter, the healthcare worker should work under aseptic conditions using sterile gloves and dressings.

After treatment with an antiseptic, the catheter is inserted into the glans penis to a depth of 20 cm or until urine appears. To relieve pain, the catheter is pre-lubricated with vaseline oil or glycerin.

A 2% solution of lidocaine can be used as an anesthetic (injected before the procedure in a volume of 2-3 ml).
