[Urethral wall pulsation in pregnant patients, continent and stress incontinent females].

The amplitudes of urethral vascular pulsations in pregnant women, continent and urinary stress incontinent women were compared with each other. Significant differences have been found in the chi 2-Test. In pregnant women the mean pulsation amplitude was 1.81 kPa, in continent women it was 1.13 kPa and in urinary stress incontinent women 0.46 kPa. Low or missing urethral vascular phenomena seem to be connected with urinary stress incontinence. That is why the amplitude of urethral pulsation should be taken into consideration in the urodynamic investigation of urinary stress incontinence.
