Handy Hints for Changing a Suprapublic Catheter 

  1. Clamp catheter just above connection to drainage bag, using spencer wells. (A catheter spigot may be used instead).
    • to allow the catheter balloon to be deflated whilst catheter is clamped.
    • to ensure urine is present in the bladder when the new catheter is inserted.
  2. Wait for up to 10 minutes.
    • to ensure urine is present in the bladder when the new catheter is inserted.
  3. After deflating the catheter balloon keep one hand as 'dirty' and the other as 'clean.
    • to remove current catheter with 'dirty' hand and to insert new catheter with 'clean' hand.
    • to minimise risk of urinary tract infection.
  4. Remove current catheter as if removing a screw.
    • to prevent trauma.
    • to allow for ridges, encrustations that may have formed around the catheter balloon.
  5. If necessary place a firm hand over the abdomen around the catheter.
    • to ease removal of catheter.
    • to prevent trauma.
  6. Remove current catheter with the 'dirty' hand and immediately pass the new catheter with your 'clean' hand.
    • to ensure that urine does not drain through the suprapubic site.
    • to minimise risk of the suprapubic tract narrowing or closing.
  7. Pass the new catheter until urine drains through it.
    • to ensure that the catheter is in the bladder prior to inflating the balloon.
  8. Pass the catheter a further 2-3cm into the bladder before inflating the balloon.
    • to ensure the balloon is inflated in the bladder.
  9. Partially inflate the balloon using up to 4ml of water, and then pull back on the catheter until you see or feel the abdominal wall (around the suprapubic site) rise.
    • to ensure the balloon is in the bladder (and not the urethra), prior to fully inflating it.
  10. Push the new catheter a further 1cm before instilling the rest of the water into the balloon.
    • to ensure the balloon is in the bladder prior to fully inflating it.

The Spinal Centre advises against the use of 100% silicone catheters as several are not licensed for suprapubic use, and can be difficult to remove due to the inability of the balloon to deflate smoothly, without causing ridges. If a patient has an allergy to latex, then it may be necessary to use a silicone catheter.

We also advise that 10ml of water is not exceeded in a catheter balloon, as this can cause irritation to the trigone which can cause an increase of spasm and autonomic dysreflexia.
