It is presumed that idiopathic overactive bladder syndrome (OBS) is due to visceral hypersensitivity. Sacral-root stimulation can restore the bladder function, but its mechanism remains uncertain. It is well-known that long-term peripheral stimulation can induce brain plasticity. Hence, we investigated whether brain reorganization occurred along with clinical improvement after sacral-root stimulation. ⋯ Our results showed that cerebral activities changed after sacral-root stimulation. The improvement in urinary urgency and urgency perception was probably due in part to brain reorganization.
