ACOUSTIC UROFLOWMETRY
From sound-based measurement to repeated recording at home.
AI-based acoustic uroflowmetry analyzes urination sounds to estimate flow characteristics and voided volume. Smartphone recording offers a way to take repeated measurements in a familiar, private home setting.
Urinary flow measurements can inform the assessment of lower urinary tract symptoms (LUTS), including in men being evaluated for benign prostatic hyperplasia (BPH). Repeated recordings add context to a clinic measurement when considered alongside symptoms and other clinical findings.
Peer-reviewed studies examine flow estimation, voided volume, digital diaries and follow-up at home. External research does not establish validated performance of UroFlow Health products.
A field-wide evidence overview
A systematic review found positive associations between acoustic and conventional measurements across several urinary flow parameters.
Smartphone-based measurement
Smartphone recordings captured flow patterns and urinary parameters that correlated with simultaneous conventional uroflowmetry.
Acoustic AI and flow patterns
A deep learning system estimated urinary flow parameters and identified expert-labeled abnormal flow patterns from smartphone recordings.
Everyday-device feasibility
Recordings from the tested smartphone and smartwatch supported urinary flow estimation in healthy volunteers under controlled conditions.
Sound-derived voided volume
A sound-based model estimated voided volume against a bodyweight-change reference, supporting digital measurement without a measuring cup.
Repeated home measurement
Repeated home recordings reflected changes in urinary flow during 12 weeks of follow-up after prostate surgery.
Patient-reported diary convenience
Participants reported greater convenience and satisfaction with the acoustic app diary than with a conventional paper diary.
