During filling cystometry, which parameter is NOT typically assessed?

• A. Bladder sensation.
• B. Detrusor activity.
• C. Blood pressure.
• D. Closing pressures.

Answer: (C)

Filling cystometry focuses on how the bladder stores urine and how the detrusor muscle behaves as it fills. You assess bladder sensation as filling progresses, detrusor pressure changes (involuntary contractions and the pressure generated by the detrusor), bladder capacity and compliance, and closing pressures that reflect urethral outlet function and potential leakage points. Blood pressure is not part of these bladder-specific measurements because it does not reveal the storage or outlet mechanics of the bladder; while vitals may be monitored for safety, the urodynamic data concentrate on intravesical pressure and related bladder function parameters.
