Portable Uroflowmetry System with Integrated Software for Home Urinary Monitoring

The dynamics of the urinary tract system are important which is an indication of the health of organs in this system. This study presents a portable, low-cost uroflowmetry system designed for home urinary monitoring, capable of detecting lower urinary tract dysfunction through real-time measurements of urine flow rate, voided volume, and voiding time. Early detection of urinary tract problems is crucial for successful treatment, and traditional clinic-based uroflowmetry, though common, can be inconvenient. To address this, an accurate home-based method for repeated uroflowmetry, allowing patients to measure when they are physiologically ready to urinate, is needed. This system used two sensors the load cell and ultrasonic. The results show that the load cell sensor achieved higher accuracy, at 91.11%, compared to 84.44% for the ultrasonic sensor, also precision (0.9285 vs. 0.8450), recall (0.9285 vs. 0.8450), F1 score (0.9284 vs. 0.8449), specificity (0.8823 vs. 0.7290), and MCC (0.8109 vs. 0.6735). Additionally, the load cell sensor produced more accurate measurements across several parameters: Qmax of 13.1 ± 5.5 ml/s, Qavg of 11.9 ± 2.7 ml/s, VV of 280 ± 75.4 ml, VT of 31.6 ± 8.1 seconds, and TF of 21.2 ± 5.5 seconds. In comparison, the ultrasonic sensor produced a Qmax of 10.4 ± 5.8 ml/s, Qavg of 7.3 ± 2.1 ml/s, VV of 320 ± 77.5 ml, VT of 33.8 ± 9.4 seconds, and TF of 26.1 ± 6.8 seconds. Collects urine in real time and analyzes the results, indicating whether the patient suffers from urinary tract disorders. Tested on 45 participants, the system proved effective in providing reliable, repeated measurements in a comfortable home setting, potentially aiding in the early detection and treatment of urinary disorders.
