Objective: The aim of the study was to investigate the effect of magnetotherapy on the basis of urodynamic tests before and after the performed magnetotherapy in female stress urinary incontinence and to compare urodynamic examination before and after the performed magnetotherapy. Study design: The study is organized as a retrospective-prospective study. Participants and Methods: Seven women with the diagnosis of stress urinary incontinence were treated at the Institute for Urology of Clinical Hospital Center Osijek. They were included in the research according to the criterion of the mentioned diagnosis, and the urodynamic treatment before and after magnetotherapy from 20th June 2017 to 20th June 2018. Data on respondents were collected in June 2018. Scheduled urodynamics was performed 24 weeks after magnetotherapy. During the urodynamic testing, the cystometric, profilometric and uroflowmetric parameters were measured and compared in the study. Magnetic stimulation therapy was performed in the outpatient clinic. All patients were treated twice a week for eight weeks. Results: The mean age of the respondents is 61 (interquartile range 50 to 61 years) ranging from 40 to 62 years. The median number of births is 2, ranging from 2 to 3 births. The largest number of subjects, 5/7 did not have an urogynecologic surgical procedure. The effect of magnetotherapy on the values of urodynamic parameters is varied. There are no statistically significant differences in the values of cystometric, profilometric and uroflowmetric parameters after magnetotherapy compared to the condition prior to the therapy. Conclusion: Magnetotherapy is a safe, noninvasive and painless method of treating stress urinary incontinence. Although no significant improvement in urodynamic values has been observed, it has a positive effect on the values of individual urodynamic parameters.
