Inclusion criteria were to perform one free flow (FF) and one intubated flow (IF) (voided volumes of at least 100 ml and continuous flow curves). Voiding parameters: volumes, maximum flow rate, detrusor pressure and flow time, were analyzed as some characteristic ratios. The VBN\u00ae model was used to make simulations of various pathophysiological hypotheses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Significant increased residual volume and flow time, decreased maximum flow rate were observed during IF. Twenty five patients had a residual volume only during IF; in that group, both decrease of Q<jats:sub>max<\/jats:sub> and increase of flow time were significant. Simulations showed that the geometrical effect of the catheter was not the only cause and allowed to propose the occurrence of a compression\u2010like effect of the urethra and of a fading of the detrusor excitation after Q<jats:sub>max<\/jats:sub> to explain the results.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Significant differences were found between the data from a FF and an IF in women with urinary incontinence.
