Overview
Brief Summary
The main hypothesis of this study is that transcranial magnetic neuromodulation can correct the symptoms of hypersensitivity and bladder pain. The investigators assume that under the influence of transcranial magnetic stimulation, both the subjective state of patients assessed by standardized questionnaires and the objective parameters assessed by invasive and non-invasive urodynamic studies will be improved. In this study, two protocols for magnetic stimulation of the supplementary motor area (SMA) will be compared with each other and with placebo. The investigators expect to determine the dependence of the therapeutic effect on the applied stimulation protocol.
Detailed Description
The aim of the study is to test the hypothesis that the use of the magnetic stimulation method SMA in patients with symptoms of bladder hypersensitivity and bladder pain will help to reduce the clinical and urodynamic signs of these pathological conditions.

Eligibility Criteria
Inclusion Criteria
- •Age \> 18 years;
- •Signed informed consent;
- •The presence of OAB symptoms: urinary frequency, nocturia, urgency and urge incontinence; discomfort during filling the bladder, pain in the projection of the bladder over the womb.
- •Resistance to standard therapy for bladder hypersensitivity and bladder pain.
Exclusion Criteria
- •The patient, who have been implanted devices that control physiological functions (a pacemaker, a device for deep brain stimulation and chronic epidural brain stimulation, a cochlear implant).
- •Convulsive attacks in the anamnesis;
- •Taking medications that may trigger the risk of seizures;
- •Pregnancy or suspicion on it;

- •Chronic cardiovascular and cerebrovascular diseases in the stage of decompensation or recent acute conditions (myocardial infarction, brain stroke, etc.)
- •A history of injuries associated with impaired conduction along the pathways of the brain and spinal cord;
- •The presence of detrusor hyperactivity patterns according to the preliminary multichannel urodynamic study;

- •The postvoid residual volume (more than 100 ml);
Outcomes
Primary Outcomes
VAPS change score
Time Frame: Baseline, 4, 12, 24, 48 weeks
VAPS is a continuous scale in the form of a horizontal or 10 cm (100 mm) long and located on it with two extreme points "no pain" and "the strongest pain that can be imagined
OAB-Q SF change score
Time Frame: Baseline, 4, 12, 24, 48 weeks
Individual participant change score on the Overactive Bladder Questionnaire short-form (OAB-q SF) will be compared between the two cohorts by student's t-test. The OAB-q SF is utilized to assess the impact of OAB symptoms on the patient's life, and has been shown to be responsive to reductions in urinary urgency, frequency and incontinence during transvertebral magnetic neuromodulation therapy. The OAB-q SF questionnaire consists of 19 items divided into a 6-item symptom severity (SS) scale and a 13-item health-related quality of life (HRQL) scale, with both scales ranging from 0 to 100. For the OAB-q SS scale a higher score indicates worse symptom severity while for the OAB-q HRQL scale a higher score indicates better quality of life.
Hospital Anxiety and Depression Scale change score
Time Frame: Baseline, 4, 12, 24, 48 weeks
The Hospital Anxiety and Depression Scale (HADS) consists of 14 questions: 7 questions assessing anxiety and 7 questions assessing the presence of depression.
Change baseline of micturition episodes per day
Time Frame: Baseline, 4, 12, 24, 48 weeks
Patients should document how many times they go to the restroom during the day and at night, as well as the loss of urine in stressful situations (coughing, sneezing, laughter, squatting, weightlifting, walking, running), changing liner or absorbent and episodes of urgency and urgency-incontinence. The journal shall be held for a consecutive period of 24 hours, for a minimum of three consecutive days.
Secondary Outcomes
- Improvement of urodynamic parameters(Baseline, 4, 12, 24, 48 weeks)
