A new method for electromyography of the female urethra.
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.
