OBJECTIVES To determine the efficacy and predictive factors for the success of Er:YAG laser treatment in patients with urinary incontinence (UI). METHODS Eighty-two patients with UI were treated by Er:YAG laser in this cohort study. The patients were evaluated by ICIQ-SF and KHQ-UI before and after the procedure. Improvement was categorized as: none (0-25%), mild (26-50%), moderate (51-75%), or high (76-100%). The duration of the treatment effect was evaluated at follow-up in relation to maximum improvement time (MIT) and total improvement time (TIT). RESULTS Forty-two patients were determined to have SUI and 40 patients MUI. The mean ISIQ-SF and KHQ-UI scores significantly improved after the procedure (p<0.0001). The SUI patients responded to the laser treatment significantly better (p<0.008). Younger women had significantly better results (p<0.008), while premenopausal women (p<0.032) and women in the early postmenopausal years (p<0.032) also saw a positive response to the Er:YAG laser treatment. Women with a lower BMI had greater improvement (p<0.011). The total laser energy expenditure during the sessions may also be a predictive parameter for the success of Er:YAG laser treatment of UI (p = 0.059). MIT and TIT were significantly longer among the patients in the high-improvement group. CONCLUSION Er:YAG laser treatment of the symptoms of UI, especially SUI, is more efficacious and of longer duration for younger, premenopausal or early postmenopausal women with normal BMI.

Er:YAG 激光治疗尿失禁疗效的预测因素

目的 确定 Er:YAG 激光治疗尿失禁 (UI) 患者成功的疗效和预测因素。方法 在这项队列研究中，82 名 UI 患者接受了 Er:YAG 激光治疗。术前和术后均通过ICIQ-SF和KHQ-UI对患者进行评估。改善被分类为：无 (0-25%)、轻度 (26-50%)、中度 (51-75%) 或高 (76-100%)。在随访时根据最大改善时间 (MIT) 和总改善时间 (TIT) 评估治疗效果的持续时间。结果 42 名患者被确定为 SUI，40 名患者被确定为 MUI。手术后平均 ISIQ-SF 和 KHQ-UI 评分显着提高（p<0.0001）。SUI 患者对激光治疗的反应明显更好（p<0.008）。年轻女性的结果明显更好 (p<0.008)，而绝经前女性 (p<0.032) 和绝经后早期的女性 (p<0.032) 也对 Er:YAG 激光治疗有积极反应。BMI 较低的女性有更大的改善（p<0.011）。会话期间的总激光能量消耗也可能是 Er:YAG 激光治疗 UI 成功的预测参数 (p = 0.059)。高改善组患者的 MIT 和 TIT 显着更长。结论 Er：YAG激光治疗UI症状，尤其是SUI，对于BMI正常的年轻、绝经前或绝经后早期女性更有效，持续时间更长。YAG 激光治疗。BMI 较低的女性有更大的改善（p<0.011）。会话期间的总激光能量消耗也可能是 Er:YAG 激光治疗 UI 成功的预测参数 (p = 0.059)。高改善组患者的 MIT 和 TIT 显着更长。结论 Er：YAG激光治疗UI症状，尤其是SUI，对于BMI正常的年轻、绝经前或绝经后早期女性更有效，持续时间更长。YAG 激光治疗。BMI 较低的女性有更大的改善（p<0.011）。会话期间的总激光能量消耗也可能是 Er:YAG 激光治疗 UI 成功的预测参数 (p = 0.059)。高改善组患者的 MIT 和 TIT 显着更长。结论 Er：YAG激光治疗UI症状，尤其是SUI，对于BMI正常的年轻、绝经前或绝经后早期女性更有效，持续时间更长。
