Er:YAG laser treatment for stress and mixed urinary incontinence
Device: IncontiLase Er:YAG laser treatment

Other Name: IncontiLase

Detailed Description:

Urinary incontinence (UI) is a common disorder that affects women of various ages and impacts all aspects of life. Therapeutic approaches range from conservative therapy, which is heavily dependent on patient compliance, to different, more invasive, surgical procedures.

The aim of the study was to evaluate the non-invasive erbium:yttrium-aluminum-garnet (Er:YAG) laser treatment (IncontiLase) as a potential treatment strategy for stress UI (SUI) and mixed UI (MUI). The treatment works by thermally affecting vaginal mucosa, with an emphasis on the anterior vaginal wall, resulting with partial denaturation of collagen fibres and stimulation if new collagen formation, all of which leads to firmer support for the urethra and the improvement of incontinence symptoms.

The investigators included 175 women with newly diagnosed SUI (66% of women) and MUI (34 %), respectively and performed on average 2.5±0.5 procedures in each woman separated by a two-month period, using Er:YAG laser. Patients were clinically examined and classified by incontinence types (SUI and MUI) and grades (mild, moderate, severe and very severe) using International Consultation on Incontinence Modular Questionnaire (ICIQ) and assessing Incontinence Severity Index (ISI): ISI before the therapy was 5.7±2.1 points. Treatment discomfort was measured at every session with visual analogue system pain scale, and adverse effects and patients' satisfaction were followed. Follow-ups were performed at two, six and twelve months after the treatment.
