Troubleshooting catheter problems

Balloon Non-deflation

Indwelling urinary catheters are medical devices and have the potential for mechanical failure. While this is a rare occurrence, due to the robust quality assurance processes employed by manufacturer, faults can occur occasionally. One rare mechanical failure that practitioners should know how to deal with is balloon non-deflation, i.e. the water will not empty from the balloon when catheter removal is attempted.

These should never be attempted for the following reasons:

- Cutting the catheter does not always result in water emptying and if the catheter is under tension it can disappear up the urethra so the patient will require removal in the operating department

- Drawing back too hard on the syringe can cause a negative pressure which will collapse the inflation channel

- A few mls of sterile water may be inserted in case a small particle has blocked the inflation channel, but large quantities that cause the balloon to burst should never be used. This would result in free fragment formation within the bladder and the patient would need to have these removed under anaesthetic.
