ELN and Stress urinary incontinence: The normal tissues existing between each beam point are heated and ablated under the action of carbon dioxide to increase the temperature controllability, which ultimately leads to vasorelaxation, collagen remodeling and synthesis, neovascularization, and elastin formation.15 Furthermore, the vaginal tissue is tightened and the urethral closure pressure is increased, thereby improving stress urinary incontinence, restoring the premenopausal state dominated by lactic acid bacteria, and improving sexual experience,16 Er-YAG and lattice carbon dioxide laser have similar effects.
