What outcome is expected from improving bladder contractility?

1. Increase in incontinence episodes

2. Enhanced ability to void

3. Lower intravesical pressure

4. Reduced frequency of urinary tract infections

The correct answer is: Enhanced ability to void

Improving bladder contractility leads to an enhanced ability to void because it allows for more effective and coordinated muscular contractions of the bladder during the process of urination. This increased contractility means that the bladder can empty more completely, which is crucial for maintaining normal urinary function. When the bladder contracts adequately, it assists in fully expelling urine, reducing the likelihood of residual urine left in the bladder after voiding. In contrast, the other options do not align with the primary benefit of improved bladder contractility. For example, an increase in incontinence episodes would not be expected as effective contractions help control urination. Similarly, while improved bladder function could potentially lower intravesical pressure, the primary outcome is related to the ability to void rather than a direct reduction in pressure. Lastly, bladder contractility influences voiding efficiency but does not directly correlate with the frequency of urinary tract infections, which are typically influenced by other factors such as hygiene and the presence of bacteria.
