The aim of the study is to test the hypothesis that the use of magnetic stimulation of the sacral spine roots (S2 - S3) in patients with idiopathic overactive bladder (OAB) will help reduce the clinical and urodynamic manifestations of bladder overactivity.
The main hypothesis of this study is that magnetic neuromodulation can be used to correct bladder overactivity. The investigators assume that the transvertebral magnetic stimulation can improve both the subjective state of patients evaluated through questionnaires and objective parameters evaluated through invasive and non-invasive urodynamic studies. This study will compare two protocols for magnetic stimulation of the sacral spine roots (S2-S3 segments). The investigators propose to find out the dependence of the therapeutic effect on the frequency of stimulation, the frequency of procedures and the duration of the treatment course.
