New methods of conservative treatment of female stress urinary incontinence are needed. We investigated whether superimposed vibration mechanosignals during Kegel exercises could reduce the amount of urinary leakage after 4 and 6 weeks of training.
Sixty women with stress urinary incontinence were included in this prospective cohort study. Vibration mechanosignals were superimposed during Kegel exercises using an intravaginal device. Each training session consisted of 15 maximal contractions of pelvic floor muscles for 5 s. The women performed training (5 min/day) at home for 4 (n = 60) and 6 (n = 36) weeks. Urine leakage (g) during stress test with standardized bladder volume, and contraction force without and with superimposed mechanical stimulations were measured at inclusion (T ), and after 4 (T ) and 6 (T ) weeks of training using an intravaginal device. Incontinence Questionnaire-Short Form was recorded at T , and in a sub-cohort of women (n = 36) at 2 years follow up.
Mean urine leakage reduced significantly from 20.5 (± 12.2) g at T to 4.8 (± 6.7) g at T and 1.5 (± 6.7) g at T . After 4 and 6 weeks of training, urinary leakage was ≤ 4 g on stress test in 44 and 49 of the 60 women, respectively. At T , the mean Incontinence Questionnaire-Short Form score was 13 (± 2.4), and at 2 years follow up, the score was 6.3 (± 3.75).

需要新的女性压力性尿失禁保守治疗方法。我们研究了在凯格尔运动中叠加振动机械信号是否能减少 4 周和 6 周训练后的尿失禁量。
本前瞻性队列研究纳入了 60 例压力性尿失禁女性。使用阴道内装置在凯格尔运动中叠加振动机械信号。每次训练包括 15 次最大骨盆底肌肉收缩，持续 5 秒。女性在家中进行训练（每天 5 分钟），持续 4 周（n=60）和 6 周（n=36）。使用阴道内装置在纳入时（T ）、4 周（T ）和 6 周（T ）后测量压力试验下的尿失禁量（g）、无叠加机械刺激和叠加机械刺激下的收缩力。在 T 时记录尿失禁问卷-短表，在亚组女性（n=36）中记录 2 年随访时的情况。
尿失禁量从 T 时的 20.5（±12.2）g 显著减少到 T 时的 4.8（±6.7）g 和 T 时的 1.5（±6.7）g。在 4 周和 6 周的训练后，分别有 44 名和 49 名女性在压力试验下的尿失禁量≤4g。T 时尿失禁问卷-短表的平均得分为 13（±2.4），2 年随访时的得分为 6.3（±3.75）。
在凯格尔运动中叠加机械刺激可显著减少女性压力性尿失禁的尿失禁量。
