Background: Laser therapy has recently been proposed as a novel treatment for stress urinary incontinence (SUI) due to offering several advantages. This study aimed to evaluate the safety and efficacy of laser treatment of SUI by a meta-analysis.
Methods:The systematic review registration number is INPLASY202080001. A comprehensive search to identify relevant studies was conducted using the PubMed, Embase, Cochrane Library, CNKI, VIP and Wanfang databases with a cutoff date of 1 November, 2020. Outcome measures were extracted based on subjective and objective indexes, including International Consultation on Incontinence Questionnaire-Short Form (ICIQ-UI-SF), Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12), and objective measurements "1-hour pad test" (1-hour test under standardized conditions). Score changes before and after treatment were evaluated through meta-analysis. Subgroup analysis was performed according to geographic region, type of urinary incontinence (UI), severity of UI, age, and body mass index (BMI).Results: Sixteen published clinical research studies, involving 899 patients with SUI, were included in this study. After laser treatment, the change in the ICIQ-SF score at 1, 2, and 6 months was −5.49 (95%
