Which of the following is NOT a recognized subtype of urinary incontinence?

• A. Stress incontinence
• B. Overflow incontinence
• C. Reflex incontinence
• D. Nociceptive incontinence

Answer: (D)

Understanding urinary incontinence types means looking at the mechanism that lets urine leak. Stress incontinence is leakage with activities that raise abdominal pressure because the pelvic floor or urethral support is weakened. Overflow incontinence happens when the bladder isn’t able to empty properly, so urine leaks as the bladder becomes distended. Reflex incontinence occurs in some neurologic conditions where the bladder contracts and empties automatically, leading to leakage without the person feeling the urge. Nociceptive incontinence isn’t recognized because nociception is about pain signaling, not a bladder-control mechanism that causes leakage. Since pain signaling doesn’t define a distinct urinary incontinence syndrome, it isn’t used as a separate subtype.
