Overflow incontinence can be caused by which condition?

• A. Detrusor overactivity
• B. Nocturia
• C. Bladder outlet obstruction
• D. Stress incontinence

Answer: (C)

Overflow incontinence happens when the bladder can’t empty completely, so urine leaks as it overfills and pressure rises. The best explanation is bladder outlet obstruction, which creates resistance to flow and leads to high bladder pressures with retained urine after voiding. Over time this can produce a measurable post-void residual and ongoing leakage as the bladder struggles to empty. Detrusor overactivity causes urge incontinence, not overflow. Nocturia is a symptom of many conditions and by itself doesn’t cause overflow. Stress incontinence involves leakage with exertion due to pelvic floor weakness, not obstruction. So obstruction at the bladder outlet is the classic driver of overflow incontinence.
