Brief summary
This single-arm pilot study aims to investigate the efficacy and safety of a combined non-ablative Erbium:Yttrium-Aluminium-Garnet (Er:YAG) laser and High Intensity Tesla magnetic Stimulation (HITS) treatment for female urinary incontinence. The study involves 25 women diagnosed with mild to moderate stress or mixed urinary incontinence. Participants will receive three vaginal Er:YAG laser treatments and six HITS sessions. The primary objective is to improve symptoms of urinary incontinence, as measured by changes in scores on two questionnaires compared to baseline. Secondary objectives include improvement in sexual function, durability of improvement in urinary incontinence symptoms at 3- and 6- month follow-up, patient-reported improvement, and discomfort during treatment.
Detailed description
The aim of this single-centre, single-arm pilot study is to investigate the combined effects of vaginal Er:YAG laser and HITS treatment on urinary incontinence (UI) in women. The study will involve 25 women suffering from mild to moderate stress urinary incontinence or mixed urinary incontinence. The aim of the study is to investigate whether the combination of non-ablative Er:YAG laser therapy and HITS can have a synergistic effect in relieving UI symptoms. Participants will undergo three sessions of intravaginal laser treatment according to the IncontiLase® Er:YAG laser protocol and six HITS sessions. The laser treatments will take place one month apart, while the HITS sessions will take place twice a week for three weeks after the last laser treatment. Primary endpoints include improvement in UI symptoms as measured by changes in International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) and Questionnaire for Urinary Incontinence Diagnosis (QUID) scores from baseline to post-treatment. Secondary endpoints include improvement in sexual function as measured by the Female Sexual Function Index (FSFI), durability of improvement in UI symptoms 3 and 6 months after treatment, patient-reported global impression of improvement (Patient Global Impression of Improvement, PGI-I), and treatment-related discomfort as measured by the Visual Analog Scale (VAS) for pain. The study also includes rigorous safety assessments and monitoring of adverse events or complaints during and after the treatments. Recruitment of participants will ensure that they meet certain inclusion criteria, such as adult women with a clinical diagnosis of stress or mixed UI, as well as exclusion criteria to minimize risks and improve compliance. Statistical analysis will be performed using various tests to check the data for normality and distribution. The results of the study should provide valuable insight into the efficacy and safety of combining laser and HITS treatments for female urinary incontinence and potentially provide a new non-invasive treatment option for this condition.
Interventions
DEVICEnon-ablative Er:YAG laser and high intensity Tesla magnetic stimulation (HITS)
Patients will initially undergo three monthly intravaginal treatments with the Er:YAG laser. Six weeks after the final laser treatment, patients will receive six sessions of magnetic stimulation. During these sessions, patients will sit on a specialized chair that generates a therapeutic magnetic field.
