Summary
This study develops a smartphone app for acoustic uroflowmetry to estimate urine flow parameters noninvasively. This innovation aims to improve accessibility for lower urinary tract symptoms (LUTS) assessment globally.
Area of Science:
- Digital Health
- Biomedical Engineering
- Urology
Background:
- Lower urinary tract symptoms (LUTS) present a significant global health challenge.
- Conventional uroflowmetry, the standard for assessing urinary flow, faces accessibility barriers due to equipment costs and availability.
- Smartphones offer a ubiquitous platform for developing innovative, low-cost diagnostic tools, especially in resource-limited settings.
Purpose of the Study:
- To develop a digital acoustic uroflowmetry system utilizing smartphone technology.
- To create a mobile application employing acoustic pattern recognition for noninvasive urine flow parameter estimation.
- To validate the system's accuracy against conventional uroflowmetry.
Main Methods:
- A staged observational study encompassing app development, algorithm training, internal validation, and clinical testing.
- Development of a smartphone app to record voiding sounds, coupled with custom signal processing algorithms.
- Comparison of acoustic uroflowmetry measurements (Qmax, Qavg, VV) with conventional uroflowmetry in recruited urology patients.
Main Results:
- The study is currently in the protocol development phase, with funding secured in May 2026.
- System and app development commenced in December 2025; participant recruitment is slated for July 2026.
- Study findings are anticipated by early 2027.
Conclusions:
- Acoustic uroflowmetry holds potential to significantly improve the accessibility and convenience of urine flow monitoring.
- This technology can particularly benefit patients in regions with limited healthcare infrastructure.
- The digital acoustic system aims to provide a viable alternative to traditional uroflowmetry.
