Intraurethral pressure changes in the external sphincter zone during voiding were recorded using a specially constructed double lumen urethral catheter in 3 normal subjects. It was noted in all the 3 subjects that the urethral pressure in this zone dropped simultaneously with decrease of electromyographic activities of the external urethral sphincter when the subjects strained to void. It was ascertained for the catheter position to remain unchanged irrespective of voiding action during urethrometrography.
使用特制的双腔尿道导管记录了3名正常受试者排尿期间尿道外括约肌区域的尿道压力变化。在所有3名受试者中都注意到，当受试者用力排尿时，该区域的尿道压力随着尿道外括约肌肌电活动的减少而同时下降。在尿道压力描记术中确定导管位置在排尿过程中无论排尿动作如何均保持不变。
