[The electromyogram of the pelvic floor within the scope of combined urodynamic examinations]

Urinary bladder, posterior urethra and floor of the pelvis form a functional unit and should therefore be taken into consideration in the same degree in the urodynamic clarification. The durect judgment of the function of the floor of the pelvis is only possible by the electromyogram. A method is described by means of which one may relatively simply write an electromyogram of the floor of the pelvis without a too largely increased apparative expenditure, which may well be combined with X-ray, measurement of pressure and flow and which also for the urologist gives an understandable information about the fact how behaves the floor of the pelvis during filling of the urinary bladder and its depletion.
