The urethral pressure profiles in 21 continent and 39 stressincontinent women were recorded by the Millar-microtransducer. An analysis of the profiles of the anterior, lateral and posterior urethral wall was performed and the most significant parameters for the urodynamic diagnosis of stress-incontinence were evaluated. It could be demonstrated, that the total tonometric urethral length, the functional urethral length and the maximal urethral closure pressure at rest are of little practical value for the urodynamic diagnosis of stress-incontinence. On the other hand an excellent correlation between urethral pressure profile under stress and anamnestic and clinical stress-incontinence was found. The analysis of the pressure profiles under stress of the anterior, lateral and posterior urethral wall showed, that these have a great variability depending on the urethral sector where the measurements are performed.
