Bladder wall compliance is the ability to:

Bladder wall compliance is the ability to:

• A. Contract without causing retrograde flow of urine into the ureters
• B. Stretch and store urine while maintaining low intravesical pressure
• C. Maintain a 90-degree angle with the urethra while sitting or standing
• D. Contract and empty in response to the autonomic-parasympathetic nerve pathways

Answer: (B)

Bladder wall compliance describes how the bladder stretches as it fills and stores urine while keeping intravesical pressure low. A compliant bladder can expand to accommodate increasing volume without a large rise in pressure, which helps protect the kidneys from back-pressure and supports continence. If the bladder becomes noncompliant, even modest filling can cause a sharp pressure rise, risking urine reflux into the ureters and upper-tract damage. The other options relate to different urinary control mechanisms: preventing backflow is about the ureterovesical junction and sphincter function, maintaining a specific angle with the urethra is about pelvic alignment, and emptying in response to parasympathetic signals describes the act of micturition, not storage.
