Systemic infections affect the bladder by which mechanism?

Systemic infections affect the bladder by which mechanism?

• A. Cause dehydration only
• B. High fever causes the kidneys to reabsorb and retain water
• C. Increase urine output
• D. Clear infection quickly

Answer: (B)

When the body is subjected to a systemic infection, fever and associated fluid losses can lead to dehydration. In response, the kidneys conserve water by reabsorbing more of it in the tubules, driven by antidiuretic hormone. This reduces urine production and makes the urine more concentrated. With less urine flowing through the bladder, there’s less flushing of bacteria, which can allow pathogens to persist or ascend in the urinary tract. So the mechanism by which a systemic infection can affect the bladder is through dehydration that prompts the kidneys to reabsorb water, decreasing urine output.
