[Measurement of urethral closure pressure profiles with stress performed by CO2-infusion in stressincontinent women: sources of error in methodology and modes of clinical application (author's transl)].

The measurement of urethral closure pressure with stress is limited by the compressibility of gasiform mediums, which causes damping of intraurethral pressure spikes. In this study damping could be reduced by alterations of the catheter and the connecting tubes of an aircystometer. With this modified technique 55 incontinent women were examined. The differentiation between stress- and urgeincontinence was clinically sufficient.
