The EMG patterns of anal sphincter and periurethral striated musculature were analyzed in 55 women with urge incontinence during cystometry. Six had a sensory urge and 49 a motor urge incontinence. In 18 cases the unstable bladder contractions were accompanied by an intense EMG activation and in 31 cases by a decrease of perineal activity. During bladder filling a progressive decline of activity was found in 9 cases and an irregular EMG pattern and urethral pressure in 18 cases. Five patients had abnormal EMG action potentials while 16 out of 39 patients had an abnormal evoked sphincter reaction. Although the EMG of the perineal muscles during bladder filling is often abnormal in women with urge incontinence, it does not give any additional information on the causes of the urethral and bladder instability.
对55例急迫性尿失禁女性患者在膀胱测压期间的肛门括约肌和尿道周围横纹肌的肌电图模式进行了分析。其中6例为感觉性尿急，49例为运动性尿急失禁。18例患者不稳定膀胱收缩伴有强烈的肌电图激活，31例患者伴有会阴活动减少。膀胱充盈期间，9例患者活动逐渐下降，18例患者肌电图模式和尿道压力不规则。5例患者肌电图动作电位异常，39例患者中有16例诱发括约肌反应异常。尽管急迫性尿失禁女性在膀胱充盈期间会阴肌肉的肌电图通常异常，但它并未提供关于尿道和膀胱不稳定原因的任何额外信息。
