Low-level Laser Therapy in Genitourinary Symptoms of Menopause
Assessing the Efficacy of Low-Level Laser Therapy in Alleviating Genitourinary Symptoms of Menopause

Detailed Description
A convenience sample of menopausal women aged more or equal to 45 years will be recruited from the gynecology clinic in our hospital and its branches. Participants will undergo an initial screening to confirm the presence of genitourinary symptoms associated with menopause. Inclusion criteria will encompass women experiencing symptoms such as urinary incontinence, vaginal dryness, dyspareunia, and decreased sexual satisfaction. The exclusion criteria will be diagnosed with advanced pelvic organ prolapse (more or equal to stage 2 prolapse by pelvic organ prolapse quantification system).
All participants will receive low-level laser therapy (LLLT) as the intervention. LLLT sessions will be conducted once a week for eight weeks. The laser therapy will be administered by a trained healthcare professional using a standard protocol, targeting the genitourinary area. The laser device will emit low-energy laser light, which is hypothesized to stimulate tissue regeneration, improve blood circulation, and alleviate symptoms in the genitourinary region.
Baseline assessments will be conducted prior to the initiation of LLLT, including demographic data collection and validated outcome measures to evaluate GSM and quality of life. These measures may include the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF), Female Sexual Function Index (FSFI), Vaginal Health Index (VHI), Incontinence Impact Questionnaire-7 (IIQ-7), Overactive Bladder Symptom Score (OABSS), Urogenital Distress Inventory-6 (UDI-6), Urgency Severity Scale (USS), King's Health Questionnaire (KHQ), and a urodynamic study with a 20-minute pad test. Follow-up assessments will be conducted immediately after the fourth- and eighth-week treatment period and at a three-month post-treatment follow-up. During these assessments, participants will complete the same validated outcome measures as the baseline assessment to evaluate changes in genitourinary symptoms and quality of life following LLLT.

Intervention / Treatment |
---|---|
Experimental: Women with genitourinary symptoms of menopause
Receive low-level laser therapy
|
Low-level laser therapy would be introduced via a vaginal probe (gain medium: Gallium-Aluminum-Arsenide, wavelength 660nm) for 30 minutes per treatment, once a week, for 8 courses.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Vaginal health
Time Frame: 20 weeks
|
Vaginal health index, each of these 5 items is evaluated by means of a scale from 1 (none) to 5 (excellent) and then the average of the scores is calculated.
A value of ≤15 (= cut-off) is generally considered for the diagnosis of low vaginal health.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Lower urinary tract symptom: incontinence
Time Frame: 20 weeks
|
ICIQ-SF: International Consultation on Incontinence Questionnaire - Short Form.
Scoring scale: 0-21.
Higher scores mean a worse outcome.
|
20 weeks
|
Lower urinary tract symptom: general
Time Frame: 20 weeks
|
UDI-6: Urogenital Distress Inventory-6.
Scoring scale: 0-18.
Higher scores mean a worse outcome.
|
20 weeks
|
Lower urinary tract symptom: life quality
Time Frame: 20 weeks
|
IIQ-7: Incontinence Impact Questionnaire-7.
Scoring scale: 0-21.
Higher scores mean a worse outcome.
|
20 weeks
|
Lower urinary tract symptom: urgency
Time Frame: 20 weeks
|
USS: Urgency Severity Scale.
The USS is scored as 0 (no feeling of urgency), 1 (mild urgency), 2 (moderate urgency), 3 (severe urgency), or 4 (inability to hold urine).
|
20 weeks
|
Lower urinary tract symptom: overactive bladder
Time Frame: 20 weeks
|
OABSS: Overactive Bladder Symptom Score.
The total score ranges from 0 to 15 points, with higher scores indicating higher symptom severity.
|
20 weeks
|
Quality of life affected by lower urinary tract symptoms
Time Frame: 20 weeks
|
KHQ: King's Health Questionnaire.
It addresses nine different domains in 21 items with a Likert scale response options (range 1-4 and 1-5 on the first option).
The domains are general health perception, incontinence impact, role limitations, physical and social limitations, personal relationships, emotions, sleep/energy, and severity coping measures.
An additional independent scale with nine questions was designed to evaluate symptom severity perception.
Scores for each domain are calculated through a complex system that manages missing values and results range from 0 to 100, with higher scores indicating a more impaired QoL.
