The present study aimed to validate a noncontact uroflowmeter developed by us. The noncontact uroflowmeter was compared to a medical uroflowmeter in terms of uroflowmetry variables. We used the uroflowmeters simultaneously to assess pseudourine and urine of healthy males, and compared the urinary flow pattern, voiding time, voided volume, and average and maximum urinary flow rates. Both uroflowmeters yielded similar urinary flow patterns. In the case of pseudourine, the two uroflowmeters differed significantly only in voiding time, which was significantly shorter with the noncontact uroflowmeter than with the medical uroflowmeter. However, with regard to urine, no significant differences were observed in the terms of uroflowmetry variables between the uroflowmeters. From these results, the possibility of using the noncontact uroflowmeter for medical use has increased.
