Which option is NOT listed as a cause of urge incontinence?

• A. Urethral stricture
• B. Neuropathic injury
• C. Obstruction
• D. Inflammation

Answer: (A)

Urge incontinence happens when the bladder muscle (detrusor) contracts involuntarily during filling, producing a sudden urge and leakage. Things that commonly trigger this are factors that irritate or disrupt bladder control, such as nerve injury affecting bladder signaling (neuropathic injury) and inflammation or infection of the bladder, which irritates the lining and promotes overactivity. Obstruction can also contribute to bladder irritability and detrusor overactivity in some scenarios. A urethral stricture, on the other hand, is a narrowing of the urethra that creates a mechanical blockage to urine flow. It mainly causes voiding symptoms like a weak stream, hesitancy, and incomplete emptying, not the involuntary bladder contractions characteristic of urge incontinence. That’s why it isn’t listed as a cause.
