Which of the following best describes prudent monitoring during CBI to ensure effectiveness?

• A. Drainage should be minimal and intermittent
• B. Quality of drainage should be continuous and not excessively bloody
• C. Always stop irrigation if any pain occurs
• D. Only check dressing for leaks

Answer: (B)

Continuous drainage reflecting an unobstructed flow is the best sign that continuous bladder irrigation is effective. When drainage is ongoing and the urine color is light pink to clear rather than excessively bloody, it indicates that the irrigation is clearing blood and debris and the catheter remains patent. This setup helps prevent clot formation and bladder distention.

Stopping irrigation at any sign of pain isn’t the right approach, because some discomfort or bladder spasms can occur and are managed with appropriate analgesia or antispasmodics rather than halting the irrigation flow. Focusing only on the dressing or leaks doesn’t provide information about how well the bladder is being flushed or whether the catheter is patent, which are crucial for the irrigation to work.
