This is the first report of the International Continence Society (ICS) on the development of comprehensive guidelines for Good Urodynamic Practice for the measurement, quality control, and documentation of urodynamic investigations in both clinical and research environments. This report focuses on the most common urodynamics examinations; uroflowmetry,… (More)
The terminology of lower urinary tract function will be standardized by the ICS. This report contains the recommendations dealing with urinary incontinence, procedures related to the evaluation of urine storage (cystometry, urethral closure pressure profile) and units of measurement.
Given adequate external squeeze upon suitable urethral geometry, continence depends on the mechanical properties of the outflow tract wall. Evidence indicates that these mechanical properties include an ability to deform and behave in a fluid-like manner.
20 patients with benign prostatic hypertrophy were admitted to a double-blind noncrossover study for evaluation of the effect of Tadenan. Using either standard clinical criteria or urodynamic data obtained by the urinary drop spectrometer, no significant effect was found for the dosage and period of administration used.
The third report continues with recommendations on procedures related to the evaluation of micturition. It covers pressure-flow relationships and residual urine. These recommendations were subject to discussion during the Seventh Annual Meeting of the International Continence Society in Portoroz, Yugoslavia, September 1977.
The urinary stream breaks up into drops shortly after leaving the external meatus. For normal males the frequency of the drops is related in a characteristic way to the flow rate. From this relation the elastic properties of an elastic constriction near the external meatus are calculated, using a theory of flow through distensible tubes. The elastic… (More)
