Genitourinary syndrome of menopause (GSM) and stress urinary incontinence (SUI) are common for women. Low-level laser therapy (LLLT) was applied for wound healing, but there was no study regarding treatment effect of GSM and SUI. This retrospective study aims to assess the efficacy of LLLT in alleviating GSM and SUI.

Between September 2022 and August 2023, all women who received LLLT for GSM and SUI at the gynecologic outpatient clinic of a hospital were retrospectively reviewed. The treatment was once a week for eight weeks. Vaginal health index (VHI) and questionnaires before and after treatment for evaluation of lower urinary tract symptoms (LUTS) and quality of life are the outcome assessment.

Inclusion Criteria:

• women with GSM and SUI
• Received LLLT at the gynecologic outpatient clinic

Exclusion Criteria:

• More or equal to stage 2 pelvic organ prolapse defined by pelvic organ prolapse-quantification system
• Ongoing urinary tract infection or vaginitis with the pathogen in the previous 2 weeks
• Bladder calculus
• Neurogenic bladder due to radical hysterectomy or injury of the central nervous system
• A preexisting malignant pelvic tumor.

The consecutive women who received LLLT at the gynecologic outpatient clinic were retrospectively reviewed. Menopause was defined as no spontaneous menstruation for at least one year. GSM is defined as vulvovaginal dryness and related symptoms, such as irritation, dyspareunia, or lower urinary tract symptoms (LUTS) including urinary urgency, dysuria, and recurrent urinary tract infection after menopause. SUI was defined as involuntary loss of urine on effort or physical exertion including sporting activities, or on sneezing or coughing.
