Which management step is recommended for recurrent encrustation leading to blockage in catheter care?

• 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)

Recurrent encrustation and blockage happen as crystals build up on the catheter over time, often when bacteria that produce urease raise the urine pH. The most effective preventive step is to replace the catheter before it blocks. This proactive change removes the accumulating encrustation and keeps the drainage pathway open, reducing the risk of sudden occlusion and the complications that come with it. Increasing fluid intake can help dilute urine but doesn’t reliably prevent encrustation, especially with urease-producing organisms. Acidifying the urine or dissolving encrustations with a citric acid solution may help with existing crystals or specific blockages, but they aren’t dependable preventive strategies for ongoing encrustation. Regular planned catheter changes directly address the issue by resetting the encrustation cycle and maintaining patency.
