A newly developed catheter enables the introduction of fine wire electrodes into the urethral striated sphincter muscle at predetermined locations and depths. Because of FET-probes electrode wires can be short, thus the signals show minimal artifacts owing to cable movement. The technique 1) facilitates registration of signals during coughing, walking, micturition and other activities, 2) is simple to perform and painless to the patient, 3) can be done by inexperienced personnel and 4) provides assurance that the electrodes are in the urethral sphincter muscle.
一种新开发的导管能够将细导线电极在预定的位置和深度引入尿道横纹括约肌。由于采用场效应管探头，电极线可以很短，因此信号因电缆移动而产生的伪影极小。该技术1）便于在咳嗽、行走、排尿及其他活动期间记录信号，2）操作简单且对患者无痛，3）可由经验不足的人员完成，4）能确保电极位于尿道括约肌内。
