Efficacy evaluation of lattice carbon dioxide laser in the treatment of female stress urinary incontinence / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the clinical efficacy and complications of lattice carbon dioxide laser in the treatment of female mild to moderate stress incontinence.Methods 30 cases of mild to moderate stress urinary incontinence in our hospital from August to October 2017 were reviewed.The average age was (46.5 ±3.5) years old,all married and has been bred,12 patients with mild stress incontinence and 18 patients with moderate stress urinary incontinence.Preoperative preparation including:1h urine cushion test measured leakage of urine,urine flow rate,residual urine,the international consultation on incontinence questionnaire (ICI-Q-SF) score,urine routine examination.Preoperative urine flow rate (31.87 ± 2.42) ml/s,preoperative (1 h) pad test (8.19 ± 2.42) ml,preoperative ICI-Q-SF score (4-8).The power was 12.5 mJ,the efficacy was 25％,and the single treatment was chosen.Urine flow rate,1 h urine pad test,residual urine test,ICI-Q-SF score,and subjective satisfaction were recorded at 1,3,6 months after operation.Results All 30 patients in this group were followed up for more than 6 months.The pad test was (2.14 ± 0.36) ml,(1.02 ± 0.54) ml,(0.80 ± 0.41) ml at 1,3 and 6 months postoperatively,which were significantly different from preoperative pad test (P ＜ 0.01,).The urine flow rate at 1,3,6 months after operation was (30.53 ± 3.15) ml/s,(32.19 ± 2.72) ml/s,(31.23 ± 5.76) ml/s,respectively,and there was no significant difference between the 3 groups (P ＞ 0.05).There was no significant difference between preoperative and postoperative urine flow rate (P ＞ 0.05).The ICI-Q-SF at 1,3,6 months after operation were 3 (1-4),3 (0-4),3 (0-4),which were significantly different from preoperative ICI-Q-SF.Among the 30 patients,3 cases had frequent urination after operation,1 case had frequent urination before operation,and became more severe after operation.The residual urine of 30 patients was negative after operation.All patients had no dysuria and no vaginal bleeding.No signs of urinary incontinence were observed after 6 months follow-up.Conclusions For patients with mild stress urinary incontinence,there is no obvious serious complication in the short term after the laser treatment of dot matrix carbon dioxide laser.The clinical treatment is safe and the leakage of urine can be improved.
