Hyperactive detrusor or detrusor instability is most closely associated with which type of urinary incontinence?

• A. Urge incontinence
• B. Functional incontinence
• C. Stress incontinence
• D. Overflow incontinence

Answer: (A)

Detrusor overactivity, or hyperactive detrusor, causes involuntary bladder contractions during filling, producing a sudden urge to void and often leakage before reaching the toilet. This pattern best matches urge incontinence, where leakage occurs in conjunction with a strong, sudden need to void. By contrast, functional incontinence arises from external factors preventing timely bathroom access, stress incontinence from leakage with coughing or lifting due to pelvic floor weakness, and overflow incontinence from incomplete bladder emptying due to detrusor underactivity or obstruction. So the hyperactive detrusor is most closely associated with urge incontinence.
