- 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.
- Wait for up to 10 minutes.
- to ensure urine is present in the bladder when the new catheter is inserted.
- 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.
- Remove current catheter as if removing a screw.
- to prevent trauma.
- to allow for ridges, encrustations that may have formed around the catheter balloon.
- If necessary place a firm hand over the abdomen around the catheter.
- to ease removal of catheter.
- to prevent trauma.
- 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.
- Pass the new catheter until urine drains through it.
- to ensure that the catheter is in the bladder prior to inflating the balloon.
- Pass the catheter a further 2-3cm into the bladder before inflating the balloon.
- to ensure the balloon is inflated in the bladder.
- 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.
- 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.
