PURPOSE: compare the outcomes verified during urodynamic investigation realized in two different positions related to urinary leak point pressure under stress and to discuss its clinical relevance. METHODS: sixty-four patients with stress urinary incontinency (SUI) aged 25-80 years old, attended, during June 2003 to September 2005 were included in this study. Patients were initially submitted to urodynamic investigation in accordance with International Continence Society (ICS) techniques in orthostatic position and just after were evaluated in seating position. RESULTS: statistical significance was obtained after evaluation of Vasalva leak point pressure (VLPP) obtained in two positions (99,8 ± 33,3 versus 102,9 ± 32,4; respectivamente, posição sentada e em pé, p<0,05). Linear regression test based on frequency analyses was applied with the purpose to verify the patient percentage allocated in confidence interval in terms of Valsalva leak point pressure in seating or orthostatic positions. A rate of 90.6% of compatibility was gotten in these results. When three unities were added to VLPP values after urodynamic investigation in seating position, it was noted that 92.2% of patients was included in this interval. CONCLUSIONS: these findings suggest that the urodynamic investigation can be realized in seating position without diagnostic a therapeutic impairment allowing higher comfort to the patients.
