Summary

1. Vaginal atrophy is the most common indication in the treatment of vaginal rejuvenation. Its main manifestation is vaginal relaxation syndrome, which may be the early symptom of female pelvic floor dysfunction. It is a common gynecological physiological change in women. Its clinical manifestations include vaginal wall relaxation, decreased elasticity, poor dryness sensitivity, internal environment disorder, and so on. Vaginal exhaust, often combined with urinary incontinence, pelvic organ prolapse, chronic pelvic discomfort and other symptoms, seriously affecting patients'health and quality of sexual life. At present, there are many treatments for vaginal relaxation,vaginal constriction and laser therapy are the most effective and widely accepted treatments. Laser therapy with small trauma and short repair time has attracted much attention. 2. CO2 fractional laser (Acupulse) stimulates fibroblasts to synthesize and secrete collagen fibers, elastic fibers, reticular fibers and organic matrix through dot exfoliation and thermal stimulation, thus thickening the vaginal wall and achieving long-term vaginal tightening effect. The heat effect of CO2 laser can stimulate vasodilation, increase blood flow, increase cell oxidation and nutrients, increase mitochondrial ATP release, activate cell function, enhance vaginal mucosal secretion, enhance secretion, normalize vaginal PH and bacterial flora, and then reduce the probability of gynecological infection. 3. It has been reported that CO2 lattice laser can stimulate collagen synthesis and rearrangement. It has also been reported that CO2 lattice laser may have important clinical significance in improving the morphology and function of vaginal epithelial cells.

Detailed description

1. Vaginal atrophy is the most common indication in the treatment of vaginal rejuvenation. Its main manifestation is vaginal relaxation syndrome, which may be the early symptom of female pelvic floor dysfunction. It is a common gynecological physiological change in women. Its clinical manifestations include vaginal wall relaxation, decreased elasticity, poor dryness sensitivity, internal environment disorder, and so on. Vaginal exhaust, often combined with urinary incontinence, pelvic organ prolapse, chronic pelvic discomfort and other symptoms, seriously affecting patients'health and quality of sexual life. At present, there are many treatments for vaginal relaxation,vaginal constriction and laser therapy are the most effective and widely accepted treatments. It should be noted that patients with vaginal constriction need anti-scar training for a long time after operation to prevent the effect of vaginal entrance narrowing and vaginal wall scar formation on the quality of life of patients during the repair period. Therefore, laser therapy with small trauma and short repair time has attracted much attention. 2. CO2 fractional laser (Acupulse) stimulates fibroblasts to synthesize and secrete collagen fibers, elastic fibers, reticular fibers and organic matrix through dot exfoliation and thermal stimulation, thus thickening the vaginal wall and achieving long-term vaginal tightening effect. The heat effect of CO2 laser can stimulate vasodilation, increase blood flow, increase cell oxidation and nutrients, increase mitochondrial ATP release, activate cell function, enhance vaginal mucosal secretion, enhance secretion, normalize vaginal Internal environment and bacterial flora, and then reduce the probability of gynecological infection. 3. It has been reported that CO2 lattice laser can stimulate collagen synthesis and rearrangement. It has also been reported that CO2 lattice laser may have important clinical significance in improving the morphology and function of vaginal epithelial cells. Our center has also passed the clinical observation ethical review of CO2 lattice laser to improve female vaginal relaxation in 2016, and completed the clinical trial at the end of 2017. The data further confirm that CO2 lattice laser can improve vaginal relaxation and is significantly effective for stress urinary incontinence.
