BLADDER-CATHETER BLOCKAGE TREATMENT

SUMMARY

1. Low urine volume: drink 2-3L/day.

2. Poor urine flow: ensure that the catheter is not kinked, empty the drainage bag regularly as flow can be affected when the bag is two thirds full.

3. Colonisation and biofilms: maintain clean catheter technique, regular catheter changes of 4-6 weeks will prevent colonisation.
- If possible, change the catheter when commencing antibiotic therapy
- Medications that have anti-bacterial properties such as cranberry & hiprex may prevent colonisation of the urine but you should check with your doctor before commencing any medication

4. Acidic urine: measure urine pH. Urine MCS to detect any urease producing bacteria. If a urease producing organism is present, alkaline therapy such as citrates or sodium bicarbonate may reduce crystallisation.

5. Encrustation: there is strong evidence that infection by Proteus mirabilis is the main cause of the crystalline biofilms that encrust and block Foley catheters, hence investigate & manage accordingly.
