Male catheterisation

 

Attention

  • Do not force catheter into urethra
  • Aseptic procedure
  • Check for latex allergy 
  • Male practitioner should do this procedure, if possible
  • Tell person that inserting catheter will cause discomfort

What you need

  • Sterile and non-sterile gloves
  • Blueys
  • Sterile catheterisation or dressing pack
  • Normal saline for cleaning
  • Urinary catheter with a balloon, or in/out catheter
    • Smaller the urethra, smaller the catheter
    • 14G or 16G for most men, 12G or less for younger boys
    • For enlarged prostates — a bigger catheter will be easier to put in than a smaller one (which is likely to turn back on itself and come back out the urethra)
  • Clean dish to catch urine
  • 2 x Sterile lignocaine anaesthetic catheterisation gel in pre-filled syringes, water-based lubricant (can help dilate the urethra) 
  • Sterile specimen jar, if needed
  • Kelly Forceps or similar (ones in dressing pack usually too small)
  • If indwelling catheter — 10mL syringe filled with sterile water, and catheter drainage bag

What you do

  • Lie man on bed, put blueys under bottom, keep upper body covered
  • Put on unsterile gloves, mask, goggles
  • Lay out dressing pack and prepare equipment using aseptic technique
  • Open catheter outer packet, drop catheter onto sterile area. Do not open inner plastic covering yet
  • Put clean dish between man's legs
  • Remove gloves, wash hands, put on sterile gloves 
  • Clean penis with cotton balls soaked in normal saline 
    • Retract foreskin if needed
    • Clean glans (top of penis) in a circular motion, then wipe from top to base
  • Drape with sterile towels
  • Hold penis upright and gently squirt lignocaine gel into urethra x 2. Wait about 5 minutes for it to work before doing next step
  • Open end of inner plastic cover to expose tip of catheter. Do not touch tip
  • Hold catheter with forceps or by plastic cover so you don’t touch it. Put into urethra — Figure 9.28

Figure 9.28  

  • Start with the penis at 90° and gently push catheter in until you meet resistance, then lower penis to 45° and continue until urine flows into collection dish
  • Aboriginal men may be sub-incised along their urethra — so the urethral opening is ventral  (underside of the penis) and the distance to the bladder is less
  • Let about 500mL urine flow into dish, then clamp or kink catheter 
    • After 5–10 minutes release and let flow finish
  • Acute retention is a much more common presentation in men — be aware of potential for post-obstructive diuresis
  • Collect urine specimen if needed, do U/A
  • If catheter indwelling (to stay in)
    • Fill balloon with sterile water from syringe — amount needed is written on side of catheter
    • Withdraw catheter slightly until resistance felt 
    • Connect urine drainage bag
    • Secure catheter — check it is not stretched tight when person moves
