Abstract

Introduction: Uroflowmetry is a good non-invasive diagnostic equipment for Urologist, but it is expensive and has limited usage at large medical center.

Objective: We want to create our own uroflowmetry that can be used widely and can be distributed to small medical center.

Material and Method: We use an electronic equipment called Load cell that transmits weight to electrical signal and records data to the computer and calculates it. After having created our equipment, we test it with the standard uroflowmetry by using water pump that creates constant flow at different level. Then, we test it with 8 subjects, each one voids 3 times on standard equipment and 3 times on our uroflow machine.

Result: Our equipment shows the same measurement as the standard equipment by using constant flow from water pump at many levels. The test with 8 subjects (total of 48 flow study) shows that our equipment has the ability to measure Qmax and volume as accurately as the standard equipment by using Intraclass correlation coefficient statistic.

Conclusion: We suggest that our uroflowmetry gives accurate results and can be used as a replacement of the standard equipment
