Abstract

Simultaneous measurements of intravesical pressure, urethral pressure, and electromyographic activity of perianal muscles were performed during bladder filling and voiding in 56 patients with neurogenic lower urinary tract dysfunction. In 21 patients simultaneous measurements were taken of the EMG activity of the striated-muscle external urethral sphincter. During bladder filling the urethral pressure was found to correspond to the EMG activity of both muscles only in those patients with normal urethral pressure. During voiding the EMG activity of neither muscle corresponded well with changes in urethral pressure. The EMG activity of perianal muscles corresponded to the activity of the external urethral sphincter during filling of the bladder but not during voiding.

摘要

对56例神经源性下尿路功能障碍患者在膀胱充盈和排尿期间同时进行膀胱内压、尿道压力和肛周肌肉肌电图活动的测量。对21例患者同时进行了尿道外横纹肌括约肌的肌电图活动测量。在膀胱充盈期间，仅在尿道压力正常的患者中发现尿道压力与这两块肌肉的肌电图活动相对应。在排尿期间，两块肌肉的肌电图活动均与尿道压力变化不太相符。膀胱充盈时肛周肌肉的肌电图活动与尿道外括约肌的活动相对应，但排尿时则不然。
