Steps

Disclaimer: Always review and follow agency policy regarding this specific skill.

1. Gather supplies: peri-care supplies, nonsterile gloves, 30 – 60 mL Luer-lock syringe for sterile specimen, alcohol wipes/scrub hubs, two preprinted patient labels, clear biohazard bag for lab sample, urinary graduated cylinder, and 10-mL syringe.
2. Perform safety steps:
   • Perform hand hygiene.
   • Check the room for transmission-based precautions.
   • Introduce yourself, your role, the purpose of your visit, and an estimate of the time it will take.
   • Confirm patient ID using two patient identifiers (e.g., name and date of birth).
   • Explain the process to the patient.
   • Be organized and systematic.
   • Use appropriate listening and questioning skills.
   • Listen and attend to patient cues.
   • Ensure the patient’s privacy and dignity.
   • Assess ABCs.
3. Verify the order and assemble the supplies on a protective drape on the table: gloves, Luer-lock syringe, alcohol swabs, sterile container, two preprinted patient labels, and clear lab specimen biohazard bag for transport to lab.
4. Perform hand hygiene and put on nonsterile gloves.
5. Check for urine in the tubing and position the tubing on the bed.
6. If additional urine is needed, clamp the tubing below the port for 10-15 minutes or until urine appears.
7. Clean the sample port of the catheter with an alcohol swab.
8. Attach the Luer-lock syringe to the sample port of the catheter and withdraw 10-30 mL of urine; remove the syringe and unclamp the tubing.
9. Open the lid of the sterile container, inverting the lid on the drape and maintaining sterility. Transfer the urine to the sterile container, preventing touching the syringe to the container; place the syringe on the drape; close the lid tightly; clean the outside of the container with germicidal wipes.
10. Remove gloves and perform hand hygiene.
11. Add information to the preprinted label: date, time collected, and your initials. Apply gloves. Place the label on the specimen container and put the container inside the biohazard bag. Remove gloves and wash your hands. Place the second label outside of the bag. Transport to the lab immediately.
12. Assist the patient to a comfortable position, ask if they have any questions, and thank them for their time.
13. Ensure safety measures when leaving the room:
    • CALL LIGHT: Within reach
    • BED: Low and locked (in lowest position and brakes on)
    • SIDE RAILS: Secured
    • TABLE: Within reach
    • ROOM: Risk-free for falls (scan room and clear any obstacles)
14. Perform hand hygiene.
15. Document the procedure and related assessment findings. Report any concerns according to agency policy.

Urinary elimination is a basic human function that can be compromised by illness, surgery, and other conditions. Urinary catheterization may be used to support urinary elimination in patients who are unable to void naturally. Urinary catheterization may be required:

• In cases of acute urinary retention
• When intake and output are being monitored
• For preoperative management
• To enhance healing in incontinent patients with open sacral and perineal wounds
• For patients on prolonged bedrest
• For patients needing end-of-life care

Catheter-Associated Urinary Tract Infections

Catheter-associated urinary tract infections (CAUTI) are a common complication of indwelling urinary catheters and have been associated with increased morbidity, mortality, hospital cost, and length of stay (Gould et al., 2009). Urinary drainage systems are often reservoirs for multidrug-resistant organisms (MDROs) and a source of the transmission of microorganisms to other patients (Gould et al., 2009). The most important risk factor for developing a CAUTI, a health care associated infection (HAI), is the prolonged use of a urinary catheter (Centers for Disease Control and Prevention [CDC], 2015). Urinary tract infections (UTIs) are the most commonly reported HAIs in acute care hospitals and account for more than 30% of all reported infections (Gould et al., 2009). Catheters in place for more than a few days place the patient at risk for a CAUTI. A health care provider must assess patients for signs and symptoms of CAUTIs and report immediately to the primary health care provider. Signs and symptoms of a CAUTI include:

• Fever, chills
• Lethargy
• Lower abdominal pain
• Back or flank pain
• Urgency, frequency of urination
• Painful urination
• Hematuria
• Change in mental status (confusion, delirium, or agitation), most commonly seen in older adults

The following are practices for preventing CAUTIs (Perry et al., 2014):

• Insert urinary catheters using sterile technique.
• Only insert indwelling catheters when essential, and remove as soon as possible.
• Use the narrowest tube size (gauge) possible.
• Provide daily cleansing of the urethral meatus with soap and water or perineal cleanser, following agency policy.
• Ensure a closed drainage system.
• Ensure that no kinks or blockages occur in the tubing.
• Secure the catheter tube to prevent urethral damage.
• Avoid use of antiseptic solutions on the urethral meatus and/or in the urinary bag.

Urinary Catheterization

Urinary catheterization refers to the insertion of a catheter tube through the urethra and into the bladder to drain urine. Although not a particularly complex skill, urethral catheterization can be difficult to master. Both male and female catheterizations present unique challenges.

Having adequate lighting and visualization is helpful, but does not ensure entrance of the catheter into the female urethra. It is not uncommon for the catheter to enter the vagina. Leaving the catheter in the vagina can assist in the correct insertion of a new catheter into the urethra, but you must remember to remove the one in the vagina.

For some women, the supine lithotomy position can be very uncomfortable or even dangerous. For example, patients in the last trimester of pregnancy may faint with decreased blood supply to the fetus in this position. Patients with arthritis of the knees and hips may also find this position extremely uncomfortable. Catheterization may also be accomplished with the patient in the lateral to Sims position (three-quarters prone).

The male urinary sphincter may also be difficult to pass, particularly for older men with prostatic hypertrophy.

There are two types of urethral catheterization: intermittent and indwelling.

Intermittent catheterization (single-lumen catheter) is used for:

• Immediate relief of urinary retention
• Long-term management of incompetent bladder
• Obtaining a sterile urine specimen
• Assessing residual urine in the bladder after voiding (if a bladder scanner is not available)

Indwelling catheterization (double- or triple-lumen catheter) is used for:

• Promoting urinary elimination
• Measuring accurate urine output
• Preventing skin breakdown
• Facilitating wound management
• Allowing surgical repair of urethra, bladder, or surrounding structures
• Instilling irrigation fluids or medications
• Assessing abdominal/pelvic pain
• Investigating conditions of the genitourinary system

The steps for inserting an intermittent or an indwelling catheter are the same, except that the indwelling catheter requires a closed drainage system and inflation of a balloon to keep the catheter in place. Indwelling catheters may have two or three lumens (double or triple lumens). Double-lumen catheters comprise one lumen for draining the urine and a second lumen for inflating a balloon that keeps the catheter in place. Triple-lumen catheters are used for continuous bladder irrigation and for instilling medications into the bladder; the additional lumen delivers the irrigation fluid into the bladder.

Indwelling urinary catheters are made of latex or silicone. Intermittent catheters may be made of rubber or polyvinyl chloride (PVC), making them softer and more flexible than indwelling catheters (Perry et al., 2014). The size of a urinary catheter is based on the French (Fr) scale, which reflects the internal diameter of the tube. Recommended catheter size is 12 to 16 Fr for females, and 14 to 16 Fr for males. Smaller sizes are used for infants and children. The balloon size also varies with catheters: smaller for children (3 ml) and larger for continuous bladder irrigation (30 ml). The size of the catheter is usually printed on the side of the catheter port.

An indwelling catheter is attached to a drainage bag to allow for unrestricted flow of urine. Make sure that the urinary bag hangs below the level of the patient’s bladder so that urine flows out of the bladder. The bag should not touch the floor, and the patient should carry the bag below the level of the bladder when ambulating. To review how to insert an indwelling catheter, see Checklist 80.

Safety considerations:  Perform hand hygiene. Check room for additional precautions. Introduce yourself to patient. Confirm patient ID using two patient identifiers (e.g., name and date of birth). Explain process to patient; offer analgesia, bathroom, etc. Listen and attend to patient cues. Ensure patient’s privacy and dignity. Assess ABCCS/suction/oxygen/safety. Apply principles of asepsis and safety. Check vital signs. Complete necessaryfocused assessments.
Steps	Additional Information
1. Verify physician order for catheter insertion. Assess for bladder fullness and pain by palpation or by using a bladder scanner.	Palpation of a full bladder will cause an urge to void and/or pain.
2. Position patient prone to semi-upright with knees raised; apply gloves; and inspect perineal region for erythema, drainage, and odour. Also assess perineal anatomy.	Assessment of perineal area allows for determination of perineal condition and position of anatomical landmarks to assist with insertion. Apply non-sterile gloves
3. Remove gloves and perform hand hygiene.	This prevents transmission of microorganisms. Remove non-sterile gloves Perform hand hygiene
4. Gather supplies: Sterile gloves Catheterization kit Cleaning solution Lubricant (if not in kit) Prefilled syringe for balloon inflation as per catheter size Urinary bag Foley catheter	Preparation ahead of time enhances patient comfort and safety. Prepare sterile field
5. Check for size and type of catheter, and use smallest size of catheter possible.	Larger catheter size increases the risk of urethral trauma. Choose smallest catheter size possible
6. Place waterproof pad under patient.	This step prevents soiling of bed linens. Place waterproof pad under patient
7. Positioning of patient depends on gender. Female patient: On back with knees flexed and thighs relaxed so that hips rotate to expose perineal area. Alternatively, if patient cannot abduct leg at the hip, patient can be side-lying with upper leg flexed at knee and hip, supported by pillows. Male patient: Supine with legs extended and slightly apart.	Patient should be comfortable, with perineum or penis exposed, for ease and safety in completing procedure.
8. Place a blanket or sheet to cover patient and expose only required anatomical areas.	This step helps protect patient dignity.
9. Apply clean gloves and wash perineal area with warm water and soap or perineal cleanser according to agency policy.	Cleaning removes any secretions, urine, and feces, and reduces risk of CAUTI.
10. Ensure adequate lighting.	Adequate lighting helps with accuracy and speed of catheter insertion.
11. Perform hand hygiene.	This reduces the transmission of microorganisms. Perform hand hygiene
12. Add supplies and cleaning solution to catheterization kit, and according to agency policy.	This step ensures preparation and organization for procedure. Add supplies as necessary
13. If using indwelling catheter and closed drainage system, attach urinary bag to the bed and ensure that the clamp is closed.	Urinary bag should be closed to prevent urine drainage leaving bag. Urinary bag
14. Apply sterile gloves using sterile technique.	This reduces the transmission of microorganisms. Apply sterile gloves
15. Drape patient with drape found in catheterization kit, either using sterile gloves or using ungloved hands and only touching the outer edges of the drape. Ensure that any sterile supplies touch only the middle of the sterile drape (not the edges), and that sterile gloves do not touch non-sterile surfaces. Drape patient to expose perineum or penis.	The outer 2.5 cm is considered non-sterile on a sterile drape. Cover patient with sterile drape
16. Lubricate tip of catheter using sterile lubricant included in tray, or add lubricant using sterile technique.	Lubrication minimizes urethral trauma and discomfort during procedure. Lubricate tip of catheter
17. Check balloon inflation using a sterile syringe.	This maintains sterility of catheter. Check balloon inflation using a sterile syringe
18. Place sterile tray with catheter between patient’s legs.	Sterile tray will collect urine once catheter tip is inserted into bladder.
19. Clean perineal area as follows. Female patient: Separate labia with fingers of non-dominant hand (now contaminated and no longer sterile). Using sterile technique and dominant hand, clean labia and urethral meatus from clitoris to anus, and from outside labia to inner labial folds and urethral meatus. Use sterile forceps and a new cotton swab with each cleansing stroke. Male patient: Gently grasp penis at shaft and hold it at right angle to the body throughout procedure with non-dominant hand (now contaminated and no longer sterile). Using sterile technique and dominant hand, clean urethral meatus in a circular motion working outward from meatus. Use sterile forceps and a new cotton swab with each cleansing stroke.	This reduces the transmission of microorganisms. Cleanse perineal area
20. Pick up catheter with sterile dominant hand 7.5 to 10 cm below the tip of the catheter.	Holding catheter closer to the tip will help to control and manipulate catheter during insertion.
21. Insert catheter as follows. Female patient: Ask patient to bear down gently (as if to void) to help expose urethral meatus. Advance catheter 5 to 7.5 cm until urine flows from catheter, then advance an additional 5 cm. Male patient: Hold penis perpendicular to body and pull up slightly on shaft. Ask patient to bear down gently (as if to void) and slowly insert catheter through urethral meatus. Advance catheter 17 to 22.5 cm or until urine flows from catheter.	This process helps visualize urethral meatus and relax external urinary sphincter. Insert catheter gently
Note: If urine does not appear in a female patient, the catheter may be in the patient’s vagina. You may leave catheter in vagina as a landmark, and insert another sterile catheter.
Note: If catheter does not advance in a male patient, do not use force. Ask patient to take deep breaths and try again. If catheter still does not advance, stop procedure and inform physician. Patient may have an enlarged prostate or urethral obstruction.
22. Place catheter in sterile tray and collect urine specimen if required.	Urine specimen may be required for analysis. Collect as per agency policy.
23. Slowly inflate balloon for indwelling catheters according to catheter size, using prefilled syringe.	The size of balloon is marked on the catheter port. Slowly inflate balloon
Note: If patient experiences pain on balloon inflation, deflate balloon, allow urine to drain, advance catheter slightly, and reinflate balloon.
24. After balloon is inflated, pull gently on catheter until resistance is felt and then advance the catheter again.	Moving catheter back into bladder will avoid placing pressure on bladder neck.
25. Connect urinary bag to catheter using sterile technique.	Keep urinary bag below level of patient’s bladder. Connect urinary bag to catheter using sterile technique
26. Secure catheter to patient’s leg using securement device at tubing just above catheter bifurcation. Female patient: Secure catheter to inner thigh, allowing enough slack to prevent tension. Male patient: Secure catheter to upper thigh (with penis directed downward) or abdomen (with penis directed toward chest), allowing enough slack to prevent tension. Ensure foreskin is not retracted.	Securing catheter reduces risk of CAUTI, urethral erosion, and accidental catheter removal. Secure catheter to patient’s leg For male patients, leaving the foreskin retracted can cause pain and edema.
27. Dispose of supplies following agency policy.	This reduces the transmission of microorganisms.
28. Remove gloves and <a href=”/clinicalskills/chapter/1-6-hand-hygiene/”>perform hand hygiene.	This reduces the transmission of microorganisms. Hand hygiene with ABHR
29. Document procedure according to agency policy, including patient tolerance of procedure, any unexpected outcomes, and urine output.	Timely and accurate documentation promotes patient safety.

Removing a Urinary Catheter

Patients require an order to have an indwelling catheter removed. Although an order is required, it remains the responsibility of the health care provider to evaluate if the indwelling catheter is necessary for the patient’s recovery.

A urinary catheter should be removed as soon as possible when it is no longer needed. For post-operative patients who require an indwelling catheter, the catheter should be removed preferably within 24 hours. The following are appropriate uses of an indwelling catheter (Gould et al., 2009):

• Improved comfort for end-of-life care
• Assisting in the healing process of an open sacral or perineal pressure ulcer
• Patients requiring prolonged immobilization (unstable thoracic or lumbar fractures, multiple traumatic injuries)
• Select surgical procedures (prolonged procedures, urological surgeries, etc.)
• Intra-operative monitoring of urinary output
• Patients receiving large-volume infusions or diuretic intra-operatively

When a urinary catheter is removed, the health care provider must assess if normal bladder function has returned. The health care provider should report any hematuria, inability or difficulty voiding, or any new incontinence after catheter removal. Prior to removing a urinary catheter, the patient requires education on the process of removal, and on expected and unexpected outcomes (e.g., a mild burning sensation with the first void) (VCH Professional Practice, 2014). The health care provider should instruct patients to

• Increase or maintain fluid intake (unless contraindicated)
• Void when able and within six to eight hours after removal of the catheter
• Inform the health care provider when he or she has voided, and measure the amount, colour, and any abnormal findings; ensure first void (urine output) is measured as per agency policy
• Report any burning, pain, discomfort, or small amount of urine volume
• Report an inability to void, bladder tenderness, or distension
• Report any signs of a CAUTI

Review the steps in Checklist 81 on how to remove an indwelling catheter.

Safety considerations: Perform hand hygiene. Check room for additional precautions. Introduce yourself to patient. Confirm patient ID using two patient identifiers (e.g., name and date of birth). Explain process to patient; offer analgesia, bathroom, etc. Listen and attend to patient cues. Ensure patient’s privacy and dignity. Assess ABCCS/suction/oxygen/safety. Apply principles of asepsis and safety. Check vital signs. Complete necessary focused assessments.
Steps	Additional Information
1. Verify physician orders, perform hand hygiene, and gather supplies.	Supplies include non-sterile gloves, sterile syringe (verify size of balloon on Foley catheter), waterproof pad, garbage bag, and cleaning supplies for perineal care.
2. Identify patient using two identifiers. Create privacy and explain procedure for catheter removal.	This ensures you have the correct patient and follows agency policy on proper patient identification.
3. Educate patient on catheter removal and post-urinary catheter care.	Patient must be informed of what to expect after catheter is removed and how to measure urine output, etc.
4. Perform hand hygiene and set up supplies.	Perform hand hygiene Raise bed to working height. Organize supplies. Position patient supine for easy access.
5. Apply non-sterile gloves.	This reduces the transfer of microorganisms. Apply non-sterile gloves
6. Measure, empty, and record contents of catheter bag. Remove gloves, perform hand hygiene, and apply new non-sterile gloves. Remove catheter securement/anchor device.	Record drainage amount, colour, and consistency according to agency policy. Always change gloves after handling a urinary catheter bag. Removing catheter securement device provides easy access to catheter for cleaning and removing. Remove catheter securement device
7. Perform catheter care with warm water and soap or according to agency protocol.	This reduces the transfer of microorganisms into the urethra.
8. Insert syringe in balloon port and drain fluid from balloon. Verify balloon size on catheter to ensure all fluid is removed from balloon.	A partially deflated balloon will cause trauma to the urethra wall and pain. Insert syringe in balloon port and drain fluid from balloon
9. Pull catheter out slowly and smoothly. Catheter should slide out slowly and smoothly.	If resistance is felt, stop removal and reattempt to remove the fluid from the balloon. Attempt removal again. If unable to remove the catheter, stop and notify physician. Pull catheter out slowly and smoothly
10. Wrap used catheter in waterproof pad or gloves. Unhook catheter tube from urinary bag. Discard equipment and supplies according to agency policy.	This prevents accidental spilling of urine from the catheter. Wrap used catheter in waterproof pad or gloves
11. Provide perineal care as required and reposition patient to a comfortable position.	This promotes patient comfort.
12. Review post-catheter care, fluid intake, and expected and unexpected outcomes with patient.	Ensure patient has access to toilet, commode, bedpan, or urinal. Place call bell within reach. Ensure first void (urine output) is measured as per agency policy. Encourage patient to maintain or increase fluid intake to maintain normal urine output (unless contraindicated).
13. Lower bed to safe position, remove gloves, and perform hand hygiene.	Lowering the bed helps prevent falls. Hand hygiene prevents the transmission of microorganisms from patient to health care provider. Hand hygiene with ABHR
14. Document procedure according to agency policy.	Document time of catheter removal, condition of urethra, and any teaching related to post-catheter care and fluid intake. Document time, amount, and characteristics of first void after catheter removal.
Data source: ATI, 2015d; BCIT, 2015b; Perry et al., 2014; VCH Professional Practice, 2014

If a patient is unable to void after six to eight hours of removing a urinary catheter, or has the sensation of not emptying the bladder, or is experiencing small voiding amounts with increased frequency, a bladder scan may be performed. A bladder scan can assess if excessive urine is being retained. Notify the health care provider if patient is unable to void within six to eight hours of removal of a urinary catheter. If a patient is found to have retained urine in the bladder and is unable to void, an intermittent/straight catheterization should be performed (Perry et al., 2014).
