Outline of Final Research Achievements

For the treatment of overactive bladder (OAB), antimuscarinic agents have long been the drug class of choice. However, they can have unpleasant side-effects, such as dry mouth, constipation, headache, blurred vision and tachycardia. In addition, the drugs can also be refractory in some patients with OAB symptoms. Therefore, we aimed to evaluate the efficacy and safety of magnetic stimulation for OAB, as well as stress urinary incontinence, with age. We confirmed restoration of malfunction with OAB by sacral neuromodulation of magnetic stimulation. Thus, magnetic stimulation is useful for urgency incontinence or stress urinary incontinence. In basic research, we confirmed that stimulation of the spinal μ-opioid receptors might be useful for the treatment of stress urinary incontinence in rats.
