According to best practice guidelines, what is the BEST option in the management of a patient who has recurrent catheter encrustation that leads to blockage?

• A. Increase fluid intake
• B. Acidify the urine
• C. Change the catheter before the catheter normally blocks
• D. Dissolve encrustations with a citric acid solution

Answer: (C)

Preventing obstruction from catheter encrustation is best achieved by changing the catheter before it blocks. When minerals crystallize inside the catheter lumen due to urine chemistry changes driven by bacteria, waiting for a blockage means the catheter is already failing to drain, which can cause bladder distension, discomfort, and a higher risk of infection. Replacing the catheter proactively restores patency and reduces the chance of an urgent blockage and related complications. In practice, clinicians use planned catheter changes at regular intervals or sooner if signs of encrustation appear, rather than waiting for a blockage to occur. While increasing fluids or attempting to acidify the urine and dissolving encrustations with a citric acid solution may have roles in specific scenarios, they do not reliably prevent recurrent encrustation and blockage like scheduled catheter changes do.
