This work evaluates the contribution of some new methods of investigation of the lower urinary tract function, including the critical evaluation of the new original options of diagnostic procedures. It assesses the validity of videourodynamic VLPP detection by comparison of three urodynamic potentials (evaluation of uroflowmetry VLPP detection, evaluation of visual VLPP detection, and evaluation of video VLPP detection using an external camera connected simultaneously to a urodynamic device). Valsalva leak point pressure is presently the most important test for urodynamic detection of female stress incontinence. The principle of this is the most accurate detection of intravesical pressure during leakage of fluid from the extrenal urethral orifice during Valsalva. The authors present the outcomes of VLPP measurements in a group of 59 women with stress urinary incontinence. In terms of these investigations, it is clear that both of these methods (visual-LPP detection and video-LPP detection) are relevant. There are no statistically significant differences between the values of these two groups. Detection of VLPP using uroflowmeter is completely unsuitable. By using a colour filling fluid the sensitivity of VLPP detection can be increased, especially if the volume of leakage is very small. In this case, the sensitivity of VLPP detection of a clear filling fluid is by as much as 22 % lower than with the use of a colour fluid.
