Which statement best describes the midurethral sling?

• A. To drain the bladder via a catheter.
• B. To provide urethral support during increased abdominal pressure.
• C. To permanently seal the urethral opening.
• D. To strengthen detrusor contractions.

Answer: (B)

The midurethral sling is designed to support the urethra and bladder neck so they remain closed when intra-abdominal pressure rises, such as during coughing or lifting. This urethral support prevents leakage in people with stress urinary incontinence caused by urethral hypermobility or sphincter weakness. It does not drain the bladder, seal the urethral opening, or strengthen the detrusor muscle of the bladder.
