Recording urinary flow and lower urinary tract symptoms using sonouroflowmetry.

Introduction: To assess the accuracy of sonouroflow (SUF), an at-home, wireless-based acoustic system for recording lower urinary tract symptoms (LUTS) and urinary flow rate, and to compare test-to-test variability in flow parameters recorded using this new portable method with those obtained by conventional uroflowmetry.

Materials And Methods: An initial pilot study evaluated the technical feasibility of the SUF system. Subsequently, test-to-test variability was compared between sonourograms (SUFm) and standard uroflowmetry recordings.
