Abstract：Objective To compare the mid-term and long-term clinical efficacy of transvaginal dot-matrix CO2 laser with that of AI temperature-controlled radiofrequency in the treatment of stress urinary incontinence.Methods Complete data of 100 patients who received treatment for stress urinary incontinence in outpatient department from January 2020 to May 2022 were retrospectively analyzed.Among them,46 patients received dot-matrix CO2 laser therapy(laser group)and 54 patients received AI temperature-controlled RF therapy(RF group).At 6 and 12 months after the end of treatment the clinical efficacy(1-hour urine pad)and the Urinary Incontinence Questionnaire(ICI-Q-SF)score of the International Urinary Incontinence Committee were compared between the two groups.Results At 6 months,the effective rate of laser group and RF group was 91.3％(42/46)and 72.2％(39/54).The total effective rate in laser group was higher than that in RF group(P＜0.05),especially in patients with mild urinary incontinence(96.4％ vs.60.0％)or age＞40 years old(88.5％ vs.60.0％).The ICI-Q-SF score of the two groups was lower than before treatment,and the score of the laser group was lower than that of the RF group[(5.21±3.07)vs.(6.59±3.64),P＜0.05].At 12 months,the effective rate in laser group was lower than that at 6 months(91.3％ vs.65.2％,P＜0.05),but there was no significant difference in RF group(72.2％ vs.68.5％,P＞0.05).There was no significant difference in effective rate or ICI-Q-SF score between the two groups.Conclusion Both transvaginal dot-matrix CO2 laser and AI temperature-controlled radiofrequency therapy are effective in the treatment of stress urinary incontinence,and the effect of laser therapy is better than that of radiofrequency after 6 months,especially for patients with mild urinary incontinence or age＞40 years,but the effect of them are similar after 12 months.
