The study values, through electromyography (emg), the stripped urethral sphyncter activity in women with stress incontinence (USI). 10 women with USI and 5 healthy women -control group- underwent urogynecologic examination, urodynamic examination and urethral electromyography examination. The endurance and extension of tension were took in the consideration. 9 women with USI had EGM showing denervation/renervation nervous damage, supported by potential’s wideness and length higher than control group (>300μV), either during relax or cough, and the trace’s absence of the interference with voluntary contraction. Only one woman with USI showed an EGM compatible with myogen damage: values <100 μV in all traces and negative anamnesis for risk factors. The Authors emphasize the role of EMG as a particular exam to study in deep the causes of urinary incontinence helpful to identify basic disorders of USI.
