Urge incontinence is often associated with which bladder condition?

• A. Underactive bladder
• B. Detrusor-sphincter dyssynergia
• C. Overactive bladder
• D. Nocturnal enuresis

Answer: (C)

Urge incontinence happens when the bladder muscle (detrusor) contracts involuntarily during filling, producing a sudden, compelling urge to void followed by leakage. This pattern is the hallmark of detrusor overactivity, which defines overactive bladder. When the detrusor contracts spontaneously, leakage can occur before a person can reach the bathroom, which is exactly what urge incontinence describes. Other conditions don’t fit this pattern. An underactive bladder involves weak contractions that hinder emptying, leading to retention rather than sudden leakage with urgency. Detrusor-sphincter dyssynergia is a coordination problem between bladder contraction and sphincter relaxation, usually from neurological injury, causing retention or obstructed flow rather than urge-related leakage. Nocturnal enuresis is bedwetting during sleep, typically in children, not the daytime urgency-plus-leakage scenario.
