Microablative fractional CO2 laser for the genitourinary syndrome of menopause: power of 30 or 40 W?

This retrospective case-control study aimed to compare 30 versus 40 W power of CO2 laser for the therapy of genitourinary syndrome of menopause (GSM). Postmenopausal women with severe intensity of dyspareunia and dryness were eligible to be included in this study. Primary outcomes were dyspareunia and dryness. Secondary outcomes were itching/burning, dysuria, frequency and urgency, Female Sexual Function Index (FSFI), vaginal maturation value (VMV), and Vaginal Health Index Score (VHIS). One laser therapy was applied every month for 3 months. Outcomes were evaluated at baseline and 1 month following the 3rd therapy. Fifty (25 per group) women were included in this study. In the 30-W group, mean improvement of dyspareunia, dryness, itching/burning, FSFI, VMV, and VHIS was 6.1 ± 1.7, 6.0 ± 1.9, 5.9 ± 2.0, 16.6 ± 6.7, 29.9 ± 13.0, and 11.0 ± 2.9, respectively (within group comparisons all p < 0.001). In the 40-W group, mean improvement of dyspareunia, dryness, itching/burning, FSFI, VMV, and VHIS was 6.1 ± 1.7, 6.5 ± 2.0, 5.2 ± 2.5, 14.8 ± 7.1, 25.0 ± 13.4, and 10.5 ± 4.1, respectively (within-group comparisons, all p ≤ 0.001). Comparison between 30 and 40 W revealed that mean improvement or presence of all GSM symptoms and clinical signs was not statistically significant different. CO2 laser therapy may improve GSM symptoms and clinical signs. This improvement did not seem to associate to power of 30 or 40 W.

Microablative fractional CO2-laser therapy and the genitourinary syndrome of menopause: An observational study.

OBJECTIVES: This study aimed to assess the effect of the Microablative Fractional CO2 Laser (CO2-laser) therapy on vaginal pathophysiology and the symptoms of the Genitourinary Syndrome of Menopause (GSM). METHODS: Postmenopausal women with moderate to severe symptoms of GSM underwent three sessions of CO2-laser therapy at monthly intervals. Participants were evaluated at baseline and 4 weeks after the last treatment. MAIN OUTCOME MEASURES: The primary outcomes were Vaginal Maturation Value (VMV) and Vaginal Health Index Score (VHIS). Secondary outcomes included symptoms of GSM, Female Sexual Function Index (FSFI), International Consultation on Incontinence Questionnaire of Female Urinary Tract Symptoms (ICIQ-FLUTS) and Urinary Incontinence Short Form (ICIQ-UI SF), Urogenital Distress Inventory (UDI-6) and King's Health Questionnaire (KHQ). RESULTS: Fifty-three postmenopausal women completed this study. VMV, VHIS and FSFI increased significantly. Dyspareunia, dryness, burning, itching, dysuria, frequency, urgency, urgency incontinence, stress incontinence and scores on the ICIQ-FLUTS, ICIQ-UI SF, UDI-6 and KHQ decreased significantly. Factors predicting for which women the CO2-laser therapy was more effective were not identified. CONCLUSION: This study suggests that intravaginal CO2-laser therapy for postmenopausal women with clinical signs and symptoms of GSM may be effective in improving both vaginal pathophysiology and reported symptoms.
