In five women with urinary retention, recordings from the striated muscle of the urethral sphincter revealed highly abnormal electromyographic (EMG) activity. Using a concentric needle electrode, recordings revealed very striking bursts of activity, referred to here as decelerating burst (DB) and complex repetitive discharges (CRD). Such EMG activity is exceedingly unusual in skeletal striated muscle and resembles most closely the rarely encountered condition of "pseudomyotonia". We suggest that this abnormal activity is associated with a failure of relaxation of the striated muscle of the urethral sphincter, which results in chronic retention.
在5例尿潴留女性患者中，尿道括约肌横纹肌的记录显示出高度异常的肌电图（EMG）活动。使用同心针电极进行记录时，发现了非常明显的活动爆发，在此称为减速爆发（DB）和复合重复放电（CRD）。这种肌电图活动在骨骼肌中极为罕见，与极少遇到的“假肌强直”情况最为相似。我们认为这种异常活动与尿道括约肌横纹肌松弛功能障碍有关，这会导致慢性尿潴留。
