In order to evaluate the possible effect environment might have upon a patient's flow pattern, a study was conducted of 50 patients (23 males and 27 females), who first voided in the privacy of an office and for whom a repeat flow measurement was later obtained in the urodynamic setting. An analysis of covariance was used to compare maximum flow rates in both areas. Male patients voided with a significantly lower maximum flow rate in the urodynamic laboratory. A calculated correction factor was derived for men (1.62), which would bring the maximum flow in the urodynamic laboratory up to the flow measurements in the office. It appears that environment does play a significant role upon the voiding parameters of men under testing situations.
