Study Summary

MS is a technology developed to non-invasively stimulate the central and peripheral nervous system, is applied in the treatment of UI. The MS technique aims to directly stimulate the pelvic floor muscles and sacral roots in the treatment of UI (3,4).

MS is a more acceptable, relatively painless, non-invasive and suitable electrical treatment method for patients with UI (5).

Data from studies suggest that MS may be beneficial for patients with UI after RP (1,2,5,6,7). In the literature, there are only 3 randomized controlled trials evaluating MS efficacy using a magnetic chair in patients with UI after RP (1,6,8) and one of them was published in Korean (6) and two of them in English(1,8). In these studies, MS was compared with pelvic floor muscle exercises (PFME) or electrical stimulation (ES) (intra-anal).Yokoyama et al.reported that MS and ES treatments had shown to provide earlier continence compared to the control group after RP. MS and ES are recommended as options for patients who want rapid recovery of postoperative UI(1).

Liu et al reported that MS was more effective than PTKE on incontinence symptoms and quality of life (8). However, as far as we know, there is no prospective randomized sham-controlled study evaluating the effectiveness of MS in patients with post-RP UI. In addition, there are no suggestions regarding MS in the guidelines on urinary incontinence management due to insufficient data (9). In this study, sham-controlled efficacy of MS will be evaluated in patients with UI after RP.

Our study is the first prospective randomized controlled trial comparing MS and Sham MS efficacy in patients with UI after RP. In this study, we aimed to evaluate the effectiveness of MS on incontinence related clinical parameters, quality of life, sexual functions, depression and anxiety in patients with UI after RP.

Study Description

This study is a prospective randomized sham-controlled study. The research will be carried out between January 2021 and June 2022 in XXX Physical Medicine and Rehabilitation (PMR) Department Urogynecological Rehabilitation Unit.

After the approval of XXX Faculty of Medicine Ethics Committee, 40 patients who admitted to XXX PMR Polyclinic with RP complaints after UI and who accepted the inclusion criteria directed to the Urogynecological Rehabilitation Unit, will be included in the study.

Patients will be informed about the content, purpose and application of the study and their written consent will be obtained.

Treatment Protocol 40 men with UI after RP who meet the exclusion and inclusion criteria will be divided into 2 groups using a table of random numbers. MS will be applied to the first group and sham MS will be applied to the second group.

Group 1: Magnetic stimulation (Active MS) Group 2: Sham MS

Group 1: Magnetic stimulation (Active MS)

Patients will be instructed to sit in a magnetic coil chair. Magnetic flux is generated in this field. This current stimulates the nerve or muscle of the pelvic floor. To administer MS, a stimulation amplitude of 200 μs and a repetition of 10 Hz for 10 minutes, 2 minutes rest in between, 50 Hz for 10 minutes (20 minutes total), 5 seconds on / 5 seconds off, in accordance with device literature will be adjusted to produce maximum stimuli with the cycle. During each treatment session, the device will be adjusted to receive patients the current intensity gradually increasing, reaching the maximum stimulation intensity. MS will be applied two days a week, 20 minutes a day, for 8 weeks, a total of 16 sessions.

Group 2: Sham MS

The Sham MS treatment program will be the same as active MS in terms of duration, frequency, current duration, current intensity and general patient experience. The same magnetic chair will be used for both groups. Sham therapy application will be applied by the coordinator of the study by placing a thin deflector lead / aluminum coated plate on the magnetic coil of the magnetic chair that prevents the magnetic flux from penetrating into the patient.

During both applications, the patients will be exposed to the same sound, vibration sensation and lighting of the device.

Patients who did not attend even one of the 16 sessions (MS and sham MS sessions) during the study period will be excluded from the study. Until the study is completed, patients will not be informed of what treatment they received. At the end of the treatment, patients in the sham group will be allowed to receive active MS treatment.
