Male and Female Cath

Overview and approach

Indications: acute or chronic urinary retention, strict hourly output monitoring in unwell patients, relief of obstruction, perioperative use, bladder irrigation, and where it is the only comfortable option for incontinence at end of life. Avoid it as a convenience; remove as soon as possible (1)(2).

Contraindications/cautions: suspected urethral injury (blood at the meatus, pelvic fracture, high-riding prostate: stop and get urology input), known stricture or recent urethral surgery, active urethral infection, latex allergy (use latex-free), and refusal of consent. Male catheterisation after prostate surgery needs senior input (1).

Equipment (1)(2): clean trolley wiped with disinfectant, apron, eye protection, two pairs of sterile gloves, catheter pack (drapes, gauze, cotton balls, gallipot), 0.9% saline for cleaning, 10 mL syringe of sterile water for the balloon, 1% lidocaine gel (10 mL in males; urethral gel in females), 12-14 Fr catheter (males; often the same in females), drainage bag, waste bin, leg tape or fixation device, chaperone.

Consent and prep: wash hands, introduce yourself and confirm name and DOB, explain in plain language (thin tube into the bladder to drain urine, mild discomfort, local anaesthetic), offer a chaperone, check allergies (latex, local anaesthetic) and ask about strictures, urethral surgery, recent infection, then consent. Give privacy and keep the patient covered.

Aseptic technique: use ANTT. Open the pack from the corners without touching the inside, build the sterile field, keep the catheter packaging label for the notes, wash hands then glove, and use a "clean hand/dirty hand" separation (non-dominant hand holds the genitalia and is non-sterile after contact).

Assessment and clinical features

Step-by-step, male (1):

  1. Clean the trolley, assemble equipment and check expiry dates. Hand hygiene, apron, introductions, consent, chaperone.
  2. Patient supine and exposed only as needed. Open the pack, add equipment to the field, pour saline over cotton balls in the gallipot. Hand hygiene and put on first sterile gloves. Place a drape under the genitals.
  3. Retract the foreskin with gauze (non-dominant hand). Clean the glans with single strokes away from the meatus, using a new cotton ball each time. Remove gloves, wash hands, re-glove, apply the fenestrated drape.
  4. Hold the penis vertical and slowly instil all of the lidocaine gel into the urethra; warn that it may sting. Wait about 3-5 minutes.
  5. Open the catheter wrapper tip only, hold the penis with gauze, warn the patient and insert the catheter slowly, peeling the wrapper back as you advance. Mild resistance at the prostate is common; if marked, stop and seek help instead of forcing.
  6. Advance to the hilt of the catheter (the bifurcation) and watch for urine.
  7. Inflate the balloon with 10 mL sterile water, asking the patient to say if it hurts; stop immediately if painful (tip may still be in the urethra). Then gently withdraw until it holds.
  8. Attach the drainage bag below bladder level, note residual volume and urine appearance, and replace the foreskin to prevent paraphimosis.
  9. Clean up, cover the patient, dispose of waste, hand hygiene, fix the catheter.

Step-by-step, female (2): same steps, but part the labia with the non-dominant hand and clean the meatus and surrounding area with single downward strokes (front to back), insert the catheter a few centimetres until urine drains (the female urethra is short), then advance a little more before inflating the balloon. No need to reposition a foreskin.

Your checklists (kept)

Female Catheterisation

  1. Introduction (You and Pt name, DOB)
  2. Due to low urine output to measure it, have you had one before
  3. Minor procedure, small plastic tube that we insert where you pass urine, into your bladder and we hook it to a bag to measure your output. It might be a bit uncomfortable
  4. There are always risks with procedures like infection and very rare risk that the tube can make a small hole in the urinary tract
  5. Do you have any questions? Would you like a chaperone? Do you give me consent
  6. Wash hands, underwear removed, waterproof sheet, frogged-leg position and cover
  7. Wash hands, gather equipment in cleaned trolley
  8. Prep bin, apron, eye wear and open pack and empty + catheter + gloves
  9. Sterile water in one tray for balloon and sterile saline on swabs for cleaning, gel for lubrication
  10. Glove up, sterile water in syringe and second glove
  11. Place drape on and clean area using sterile swab anterior posterior and remove blue gloves
  12. Open catheter and lube up and insert it where you pass urine until end
  13. Empty syringe of water into balloon and pull till resist
  14. Connect to drainage bag and clean up the area of lube
  15. Remove drape cover and clean
  16. Tape catheter to leg
  17. Please let someone know if anything feels uncomfortable and ill let you rest now
  18. Clean hands
  19. Documentation (in-patient notes record, date, time, procedure, size of catheter, reason for insertion and plan, name and sig)

Male Catheterisation

  1. Introduce yourself and patient confirmation
  2. I heard you are having trouble passing urine and it is getting uncomfortable and I have been told to insert a urinary catheter into your bladder to drain it to make you feel better
  3. Have you ever had a catheter in before? Urinary catheter is a small plastic tube that we insert through the penis into the bladder that allows us to drain the urine into the bag. it is a minor procedure and there are always risks associated to it like infection (we try minimise the risk by using sterile equipment ). Rarely a small hole can be made in the urethra when we insert it and we have to mention it however rare it is. It may feel discomfort and it is common so we can provide panadol. There can be some blood in the urine which is quite common. Do you have any questions? Can I put the catheter in?
  4. Wash hands, underwear removed, waterproof sheet, supine position
  5. Have you had any recent infections, strictures, operations down there? Any allergies to local anaesthetic
  6. Wash hands, gather equipment in cleaned trolley
  7. Prep bin, apron, eye wear and open pack and empty + catheter + gloves + leg tape
  8. Sterile water in one tray for balloon and sterile saline on swabs for cleaning, local anaesthetic gel for lubrication
  9. Glove up + syringe water + double glove + drape over
  10. Clean around penis using saline (+ retract foreskin)
  11. Ask for allergies then add gel into penis + usually wait 2-3 mins for LA to work
  12. Insert catheter slowly, then blow balloon up and pull down catheter + pull down foreskin
  13. Connect to drainage bag so bladder can empty and clean up area
  14. Remove drape cover and clean
  15. Tape catheter to leg
  16. Please let someone know if anything feels uncomfortable (pain, discomfort, bleeding) and ill let you rest now
  17. Clean hands
  18. Documentation (in-patient notes record, date, time, procedure, size of catheter, reason for insertion and plan, name and sig)
Differentials and investigations

Complications: UTI/CAUTI (the commonest), pain, urethral trauma or false passage, haematuria, bladder spasm, paraphimosis if foreskin left retracted, balloon inflated in the urethra, retention from blockage, allergy (latex, lidocaine), and later encrustation or blockage (1)(2).

Troubleshooting:

  • No urine despite full insertion: advance fully, check the position, gently reposition, check the patient truly has urine (bladder scan if available) and that the tube is not kinked.
  • Resistance: stop, give more gel, ask the patient to relax or cough; do not force. Seek senior or urology help (possible stricture, enlarged prostate). A coude tip or urology-led insertion may be needed.
  • Pain on balloon inflation: deflate and advance further; do not inflate in the urethra.
  • Bypassing/leaking: blockage, wrong size, bladder spasm, constipation.

What to check: residual volume and colour of urine on insertion (clear, blood-stained, cloudy); send a catheter specimen of urine (CSU) only if clinically indicated (symptoms of infection), not routinely.

Management and follow-up
  • Aftercare: drainage bag below bladder level and off the floor, keep a closed system, secure catheter to the thigh to avoid traction, daily meatal hygiene with soap and water, regular reviews of need, document a trial of void/removal date (1)(2).
  • Monitor: urine output, haematuria, signs of infection (fever, suprapubic pain), and patient comfort. Ask nursing staff to chart output.
  • Escalate: failed or traumatic catheterisation, heavy haematuria, clot retention, suspected false passage or retention after prostate surgery: urology.
  • Handover: ISBAR including indication, catheter size, balloon volume and date inserted, residual urine, any difficulty, and planned removal date.
  • Documentation (1)(2): your name, role and sign; date and time; consent and chaperone name; indication; catheter size and type; balloon volume; local anaesthetic used; any difficulty or complications; residual volume and urine appearance; plan for review/removal; stick the catheter label in the notes.
Red flags and clinical pearls
  • OSCE tips: verbalise the sterile technique (hand hygiene, glove changes, single-stroke cleaning, clean/dirty hand), give the full explanation with chaperone and allergies, anaesthetise males with adequate dwell time, warn before each step, and always ask about pain.
  • Common mistakes: touching the sterile catheter or field, inflating the balloon before urine is seen, forcing against resistance, forgetting to replace the foreskin, hanging the bag above the bladder, not documenting balloon volume and catheter type.
  • Red flags: blood at the meatus, trauma history, high-riding prostate, severe pain, no urine after full insertion with a distended bladder, fever or rigors after catheterisation, heavy haematuria with clots.
  • Geeky Medics describes UK practice (GMC number, lidocaine gel instillation, catheter sizes). Australian hospitals vary (for example, ANTT and the catheter insertion bundle, ACSQHC Australian Guidelines for the Prevention and Control of Infection in Healthcare apply).
