[New trends in urodynamic investigation].
Urodynamic approach to the disorders of the urinary tract has been based on the knowledge of anatomy and neurophysiology of this abnormality. The development of this field included uroflowmetry, cystometry, urethral profilometry, and electromyogram of the external sphincter. In addition to these investigations new trends in urodynamic field were reviewed. With the advent of muscle biochemistry intra-renal urodynamics has been advocated. These researches would be expected to clarify the mechanism of intra-renal reflux. The another investigation was urophonography. When the urine passed through the posterior urethra the urethral sound occurred. The detecting, recording and analyzing systems were developed. This method would be entirely a new method of urodynamic study.
