Overflow incontinence is due to either bladder outlet obstruction or which other problem?

• A. Detrusor overactivity
• B. Inadequate bladder contractions
• C. Bladder outlet obstruction
• D. Urinary tract infection

Answer: (B)

Overflow incontinence happens when the bladder can’t empty properly, so urine leaks as the bladder becomes overfilled. This can occur for two main reasons: a blockage at the bladder outlet (like enlarged prosthetic or urethral narrowing) or a weak detrusor muscle that can’t generate a strong enough contraction to fully empty the bladder. When the detrusor contractions are inadequate, residual urine builds up and leaks out, producing overflow. Detrusor overactivity leads to urge incontinence with leakage driven by urgency, not chronic retention. A urinary tract infection can irritate the bladder but doesn’t by itself cause the chronic underemptying that leads to overflow. So the other problem is inadequate detrusor contractions.
