Researchers compared the data from a new MenHealth® uroflowmetry app to that from a conventional uroflowmetry used in doctors’ offices. The MenHealth uroflowmetry smartphone app measures the volume of urine passing through the urethra as it hits a bowl full of water. The software computes peak and average flow rates and the volume lost. There were exams taken just on adult males. In the first group, made up of 47 men, the signs of an overactive bladder and/or outlet obstruction were seen. In the 2nd group, 15 males reported no urinary issues.
Each subject performed a minimum of 10 self-measurements using the MenHealth uroflowmetry device and 2 in-office tests using a standard uroflowmetry. The highest and lowest rates of flow, as well as the average and total volumes of voids, were all measured. In addition, the Bland-Altman analysis and the Passing-Bablok nonparametric regression analysis were used to compare MenHealth uroflowmetry results to those from an in-office uroflowmetry. When comparing MenHealth uroflowmetry to an in-office uroflowmetry, regression analysis revealed a very significant correlation between maximal flow rate and average flow rate (Pearson’s correlation values of .91 and .92, respectively).
The high correlation between the 2 techniques and the precision of MenHealth uroflowmetry is further supported by the fact that there is no discernible difference between the mean maximum and average flow rates for Groups 1 and 2 (<0.5 ml/second). MenHealth’s innovative uroflowmetry app yields result comparable to those obtained with a traditional in-office uroflowmeter for both men with and without voiding symptoms. Uroflowmetry from MenHealth can be performed at the convenience of a patient’s home, allowing for more frequent measurements and a more accurate picture of the patient’s pathophysiology and reduced likelihood of misdiagnosis.
