Detailed electromyographic investigation of the external urethral sphincter was done as part of a urodynamic evaluation of 119 patients. The sphincter was located by inserting electrodes alongside the urethra. The electromyogram was viewed on an oscilloscope and recorded on paper. Normal and abnormal sphincter electromyograms were defined and the role of sphincter electromyography in urodynamic studies was discussed. It was observed that electromyographic activity does not always correlate with urethral resistance but must be interpreted in conjunction with other urodynamic parameters, such as urethral pressures, urinary flow rates and voiding cystourethrography. In addition, sphincter electromyography provides valuable information to define the various neural pathways involved in micturition and continence.
作为对119例患者进行尿动力学评估的一部分，对外尿道括约肌进行了详细的肌电图检查。通过将电极沿尿道插入来定位括约肌。肌电图在示波器上显示并记录在纸上。定义了正常和异常的括约肌肌电图，并讨论了括约肌肌电图在尿动力学研究中的作用。观察到肌电活动并不总是与尿道阻力相关，而必须结合其他尿动力学参数，如尿道压力、尿流率和排尿期膀胱尿道造影来解释。此外，括约肌肌电图为确定排尿和控尿过程中涉及的各种神经通路提供了有价值的信息。
