The efficacy and feasibility of fractional CO2 laser therapy for the treatment of urinary incontinence: a multicentric case-control study

Background: Female urinary incontinence is a significant public health problem. Conservative treatments require high patient compliance, while surgery often leads to more complications and recovery time. Our aim is to evaluate the efficacy of microablative fractional CO2 laser (CO2-laser) therapy in women with urinary incontinence (UI). Methods: This is a retrospective analysis of prospectively collected data on women with stress urinary incontinence (SUI) and mixed urinary incontinence (MUI) with predominant SUI subjected to four sessions of CO2-laser therapy performed once a month, between February 2017 and October 2017, with a 12-month follow-up. The subjective Visual Analogue Scale (VAS) 0-10 was used to score and variables were evaluated at baseline and at one, six and 12 months after initiation of therapy. Finally, results were compared to a control group. Results: The cohort consisted of 42 women. The proportion of patients with vaginal atrophy among those younger than 55 years was substantially lower (3/23; 13%) than among those older than 55 years (15/19; 78.9%). CO2 laser treatment was associated with a significant improvement in VAS scores recorded one-month, six-months, and one-year, after conclusion of therapy (P<0.001). VAS scores improved significantly in patients with either SUI (26/42; 61.9%) or mixed UI (16/42; 38.1%). No major post treatment complications were registered. Women with vaginal atrophy demonstrated significantly better results (P<0.001). Conclusions: Results confirm the efficacy and a good safety profile, for CO2 laser treatment in SUI, mostly in women with postmenopausal vaginal atrophy and should be considered as a treatment option for female patients with concomitant SUI and vaginal atrophy.
