Which clinical outcome best reflects the therapeutic aim of SNM in overactive bladder?

• A. Reduction in involuntary bladder contractions
• B. Increase in urinary urgency
• C. Weight gain
• D. Improved sleep apnea

Answer: (A)

Sacral neuromodulation works by modulating the neural signals to the bladder to quiet detrusor overactivity, especially during the filling phase. The best clinical outcome that reflects this aim is a reduction in involuntary bladder contractions, because fewer spontaneous contractions directly translate to less urgency and better storage of urine. The other options don’t align with the therapy's purpose: increasing urinary urgency would contradict the goal, and weight gain or improved sleep apnea are not expected outcomes of SNM for overactive bladder.
