Which test measures bladder function by filling and evaluating the bladder with sterile water?

• A. Urodynamic Testing
• B. Bladder Diary
• C. Indwelling Catheters
• D. Topical Estrogen

Answer: (A)

Assessing bladder function by filling the bladder with sterile water and observing how it behaves under controlled conditions is done with urodynamic testing. This procedure uses a catheter to introduce sterile fluid into the bladder while sensors measure intravesical pressure, detrusor muscle activity, and the pressure-flow relationship during filling and voiding. It yields objective data on bladder capacity, compliance (how well the bladder stretches to hold urine), and whether the detrusor muscle contracts at inappropriate times or whether there is obstruction to outflow. This information is especially helpful for older adults with complex incontinence patterns or when planning treatments that may involve surgery, as it clarifies the underlying dysfunctional mechanism. Bladder diaries document when and how much a person voids and their incontinence episodes—useful for pattern recognition but do not involve filling the bladder with sterile fluid. Indwelling catheters are devices for draining urine, not diagnostic tests of bladder function. Topical estrogen is a therapy to treat urogenital symptoms, not a test of bladder function.
