Urinary Catheter Removal: Balloon Deflation, Withdrawal & Void Watch
End indwelling urethral drainage with a structured trial of void: confirm the order, fully deflate the balloon, withdraw without force, then monitor for anuria or incomplete emptying using your unit protocol—not guesswork at handover.

Quick facts
Key takeaway
Catheter removal is not finished when the tube leaves the patient—the trial of void starts then. Fully deflate the balloon, measure final output, document the first void honestly, and escalate early when the bladder stays full or the patient cannot pass urine within protocol.

What is urinary catheter removal?
Urinary catheter removal is the controlled discontinuation of an indwelling urethral catheter (commonly a Foley): the retention balloon is deflated, the catheter is withdrawn without traction on surrounding tissue, and the patient is supported to void spontaneously while nurses watch for incomplete bladder emptying or acute anuria. It is the closing step of a catheter episode—not a passive “pull and go” task.
Safe removal pairs technical steps with a trial-of-void mindset: confirm the order, measure final catheter output, teach what “normal” first void feels like, and document time-to-void and any dysuria. Principles align with Royal Marsden Manual — urinary catheter removal and CAUTI prevention guidance in References; proprietary Marsden step text and illustrations are not reproduced here.
Trial-of-void readiness gate (before you deflate)
Removal is appropriate only when the care plan supports spontaneous voiding. Use this bedside gate—if any “hold” item applies without a new prescriber plan, do not remove until clarified.
- Written or verbal order to discontinue the catheter (or protocol authorising nurse-led removal).
- Patient is alert enough to void or report inability; call bell within reach.
- Commode, toilet, or bedpan available; privacy and mobility support arranged.
- Fluid intake plan supports voiding trial per team (unless fluid restriction ordered).
- No active requirement for strict hourly catheter output (e.g. some post-op or critical-care pathways—confirm).
- Continuous bladder irrigation still running or gross haematuria pathway not yet cleared.
- Recent urologic or pelvic surgery where voiding trial timing is surgeon-specific.
- Unresolved blood in urine with clot risk and no plan for post-removal monitoring.
- Patient cannot participate (e.g. severe delirium) without a documented alternative plan.
- Suprapubic or alternate route in place—this guide addresses urethral indwelling removal; abdominal routes follow separate orders.
Overview
On busy wards, catheter removal is often scheduled at change of shift—yet the risk window opens after withdrawal, when bladder tone and outlet obstruction may not declare themselves for hours. Pair removal with hand hygiene, final output measurement using urinary output measurement technique, and honest charting on the intake and output record.
CDC emphasises removing unnecessary urinary catheters promptly to reduce catheter-associated infection risk—each day indwelling increases exposure. If the patient required insertion for benign prostatic hyperplasia or outlet obstruction, post-removal retention remains a leading complication; link symptoms to bladder scan or clinician review rather than silently reinserting without an order.
Clinical indications for removal
- Catheter no longer meets an accepted indication (accurate output achieved another way, perioperative phase ended, retention resolved).
- Planned trial of void after urology, surgery, or medicine review.
- Patient preference and clinical agreement when long-term catheter is no longer appropriate (document shared decision).
- Transition to intermittent catheterisation or alternative management per specialist plan—not covered by this urethral removal guide but must be explicit on the chart.
- Discharge planning when community services will support voiding without an indwelling catheter.
When to delay removal or seek medical review first
- No order or protocol authorising discontinuation.
- Active gross haematuria / irrigation unless the team has specified removal timing.
- Expected inability to void without a post-removal monitoring or re-catheterisation pathway (e.g. some neurologic injuries—specialist led).
- Suspected urethral injury during prior insertion—needs examination before withdrawal.
- Alternate drainage route (suprapubic only, nephrostomy)—follow route-specific procedures; see suprapubic catheter care for abdominal devices.
Equipment checklist
Patient preparation
- Verify identity and compare the catheter label with the chart (size, insertion date if recorded).
- Confirm order for removal and any post-removal voiding schedule (e.g. void within 6–8 hours—follow local protocol).
- Explain the procedure: brief discomfort at withdrawal, expectation to void, and importance of reporting inability, pain, or fever.
- Position the patient supine or semi-Fowler with hips slightly flexed if tolerated; ensure dignity and warmth.
- Perform hand hygiene; apply gloves when handling the catheter and drainage bag.
- Empty and measure final catheter output before deflation—record colour and volume on I&O.
Geriatric note: Older adults may have reduced sensation of fullness—use scheduled prompts and objective void checks rather than assuming they will call. Paediatric note: Follow child-specific volumes and family teaching per paediatric protocol; parental involvement reduces fear at withdrawal.
Balloon deflation and withdrawal mechanics
Most complications at removal come from skipped verification steps, not from the seconds of withdrawal itself.
| Step | Nursing focus | Common error |
|---|---|---|
| Locate balloon port | Use the inflation valve on the catheter stem—not the drainage lumen. | Attempting to aspirate from the wrong port. |
| Deflate fully | Aspirate until resistance changes per policy; note volume removed if required. | Partial deflation causing urethral trauma on pull. |
| Withdraw smoothly | Ask the patient to breathe slowly; withdraw in one steady motion without yanking. | Tugging while the patient clenches—pain and false “retention” from spasm. |
| Inspect tip | Confirm balloon appears deflated and intact on the catheter tip when visible. | Discarding catheter before tip check if policy requires integrity documentation. |
If withdrawal meets resistance or the patient reports severe pain, stop, reassure, and notify the prescriber—do not force. Institutional protocols may vary for irrigation or urology review.
Step-by-step removal procedure
Hand hygiene and preparation
Complete preparation above; close drainage clamps only if your policy requires before disconnection.
Deflate the retention balloon
Attach syringe to the inflation valve; aspirate until the balloon is fully deflated per manufacturer guidance.
Remove securement and disconnect bag
Remove leg straps or adhesive holders; minimise dragging on the urethra. Keep the closed bag low until disposal.
Withdraw the catheter
Gently withdraw the catheter; offer perineal cleansing and a fresh pad or linen as needed.
Dispose and hygiene
Dispose of the catheter as infectious waste per policy; perform hand hygiene; remove gloves.
Facilitate first void
Encourage oral fluids if not restricted; assist to toilet or provide bedpan; start voiding clock per protocol.
Assess and document
Record time of removal, final catheter output, patient tolerance, first void time/volume, and any adverse signs—see Documentation.
Post-removal voiding watch
The highest-risk period is the first voids after removal. Use scheduled checks aligned with your trial-of-void protocol.
| Finding | Nursing action |
|---|---|
| No void within protocol window | Assess suprapubic fullness, discomfort, and vitals; notify prescriber; prepare for bladder scan or re-catheterisation per order. |
| Frequent small voids with fullness | Suspect incomplete emptying—compare with incomplete bladder emptying; escalate for residual volume assessment. |
| Painful urination with fever | Consider urinary tract infection; obtain clean-catch urine specimen and urinalysis when ordered. |
| Comfortable void with adequate volume | Continue fluid plan, patient teaching, and routine I&O; document successful trial. |
If re-catheterisation is required, document why the trial failed objectively (times, volumes, scan results)—this supports quality review and CAUTI stewardship.
Post-procedure care
- Reassess skin integrity at the perineum; manage moisture-associated damage if the patient was catheterised long term.
- Continue mobility and toileting assistance to reduce falls on urgent trips to the bathroom.
- Maintain fluid intake unless restricted; monitor for fluid overload in heart failure per wider care plan.
- Remove “catheter in situ” signage and care-plan alerts; update handover with voiding plan.
- Reinforce hand hygiene after toileting—especially before meals.
Common complications
- Acute urinary retention — inability to void with bladder fullness; may need reinsertion or bladder scan.
- Urethral trauma or bleeding — often linked to forceful withdrawal or incomplete balloon deflation.
- Dysuria and bladder spasm — common briefly; persistent severe pain needs review.
- UTI symptoms — may surface after catheter days; do not assume “normal” without assessment.
- Incontinence — new leakage may reflect overflow or infection; assess rather than dismissing as expected.
When to escalate
- No void within the time frame defined by your trial-of-void protocol.
- Persistent lower abdominal pain or palpable suprapubic distension.
- Frank haematuria, clots, or heavy bleeding after removal.
- Fever, rigors, or confusion with urinary symptoms.
- Suspected balloon integrity issue (incomplete tip, resistance on withdrawal).
- Anuria with painful distension, vomiting, or haemodynamic instability.
- Signs of sepsis after recent catheterisation.
- Severe uncontrolled bleeding from the urethra.
Nursing documentation
Objective charting supports continuity when multiple nurses cover the voiding window.
Example note: “Indwelling urethral catheter removed 09:40 after MD order. Final catheter output 320 mL clear yellow. Balloon deflated without resistance; catheter tip intact. Patient voided 180 mL at 11:15 without dysuria. Trial-of-void plan: notify if no void by 17:40. Handover updated.”
- Date/time of removal and confirming clinician order.
- Final catheter urine volume and appearance.
- Balloon deflation tolerance and catheter tip integrity if inspected.
- First void time, estimated volume, and symptom report.
- Patient education provided and escalation parameters given.
- Any re-catheterisation or bladder scan results if the trial fails.
Clinical pearls for nurses
- Schedule removal when staff can monitor the first void—not five minutes before handover without a plan.
- Compare insertion indication with removal readiness; if inserted for outlet obstruction, retention watch is non-optional.
- Teach patients that burning on the first void can occur briefly; inability to pass any urine is the red flag.
- Do not reinsert “just in case” without assessment—each reinsertion restarts CAUTI risk.
- Pair successful trials with updated mobility and toileting goals to prevent the next unnecessary catheter.
Patient education
- Explain that the bladder may take time to wake up—report no urine, severe pain, fever, or chills.
- Encourage fluids if ordered; show how to measure voids if home monitoring is required.
- Review signs of UTI and when to seek urgent care after discharge.
- For men with prostate symptoms, reinforce follow-up if stream remains weak—link to ongoing BPH management, not automatic re-catheterisation.
NCLEX practice questions
After the Foley comes out, retention often hides behind a normal-looking handover—practise NCLEX-style clinical judgment practice for urinary catheter removal with a priority action when voiding fails, select-all-that-apply trial-of-void cues, post-removal trend interpretation, matrix escalation for retention versus infection, and ordered safe-removal steps (recognise cues → analyse → prioritise → act → evaluate outcomes).
Unfolding case — surgical ward. Mr. Okonkwo, 78, day 4 after hip fracture repair. Indwelling catheter placed for accurate output monitoring. Order received: discontinue catheter and trial of void. Vitals: temperature 37.2 °C, heart rate 88/min, blood pressure 128/72 mmHg. Final bag output 240 mL clear yellow. He is alert, uses a walker, and asks when he can “get rid of the tube.” No bladder irrigation running.
Answer key & rationale
Frequently asked questions
Is urinary catheter removal painful?
Many patients feel brief discomfort or burning during withdrawal and on the first void. Severe or persistent pain, or inability to void, is not expected—report and assess.
How long until the patient should void after removal?
Institutional trial-of-void protocols vary—commonly the first void is expected within several hours. Follow your unit policy and notify the prescriber if no void within the defined window.
What if the balloon will not deflate?
Stop, do not force withdrawal, and notify the prescriber or urology service per policy. Cutting the catheter at the hub is a last-resort, competency-specific intervention.
Can nurses remove catheters without a physician present?
Many organisations allow registered nurses to remove indwelling catheters with an order or approved protocol. Confirm local policy and competency before proceeding.
When should the catheter be reinserted?
When retention is confirmed and the care team orders re-catheterisation—usually after assessment, bladder scan, or failed trial with symptoms. Do not reinsert without an order.
Does removal reduce infection risk?
Yes—each day without an indwelling catheter lowers exposure to catheter-associated urinary tract infection. Continue standard infection prevention after removal if voiding is difficult.
