ABSTRACT
OBJECTIVE:
To design a new portable home electronic uroflowmeter and compare it with traditional methods.METHODS:
The system consists of collectors, urine conducting apparatus, intelligent cell phone, wireless network communication technology, computer analysis and drawing, and data storage technology, etc., and can automatically collect voiding information from patients with lower urinary tract symptoms(LUTS) Through Bluetooth, the voiding information was sent to the patient's intelligent cell phone from the collector, then stored directly by intelligent cell phone and wirelessly transmitted to the workstation in hospital. The system was primarily tested with regard to accuracy of measurement of the voided volume. Multiple doses with known volume were introduced in the system and Laborie uroflowmeter. Furthermore, 38 outpatients who had LUTS were tested simultaneously with the system and Laborie uroflowmeter. The statistical method for assessing agreement between the two methods of clinical measurement was Bland-Altman analysis. Among the subjects, there were 22 male patients and 16 female patients, ranging from 21 to 37 years old, with an average age of 25.5 years, of whom, 19 were tested once and 19 patients twice, equaling to 57 tests.RESULTS:
The system could accurately collect and analyze voiding time, uroflowmetry, voided volume, and automatically provide uroflowmetry parameters. The measurement error of 100, 200, 300, 500 and 800 mL is less than 5%. 12.28%, 5.26% and 3.51% of the Qmax, Qave and voided volume points were beyond the 95% limits of agreement. The maximum absolute values of the Qmax, Qave and voided volume difference were 0.38 mL/s, 0.70 mL/s and 2.90 mL, respectively.They agreed with the recommendation of Standardization International Continence Society.CONCLUSION:
The new portable home electronic uroflowmeter has good agreement with Laborie uroflowmeter,and is a new LUTS monitoring system integrated with correct, reliable, real-time, convenient and easy-managing advantages. It is as noninvasive and reliable as traditional methods, and its portable feature facilitates application out of hospitals. It can also record voiding diaries.
