Washrooms were designed in both western and eastern styles. UDS indexes were compared regarding voiding habits. Results: Comparison of uroflowmetric indexes between different genders and voiding positions showed differences which were not statistically significant but considering the voiding habits, uroflowmetric indexes were significantly different in familiar compare to unfamiliar voiding position. Q-Max was lower and time to Q-Max and micturition time were longer in unfamiliar voiding position. Conclusions: Urodynamic studies in children should be performed in preferred voiding position for each kid considering the culture and voiding habits. Unfamiliar voiding position may turn the uroflowmetry to a stressful experience for child that make him uncooperative and cause misleading results.
