Abstract

The present study proposed a method of measuring uroflow and urophonography at the same time for more accurate diagnosis in case uroflow looks normal due to compensatory function hypertrophy in the expression of early obstruction. In case of early obstruction, there happens turbulent uroflow by the obstruction even if the uroflow looks normal and thus obstruction can be detected by measuring and analyzing signal caused by turbulent flow. We implemented a system that can measure both uroflow and urophonography, and evaluated its performance. In the experiment, we observed changes in uroflow and urophonography according to artificial pressure and the degree of obstruction, and confirmed that it is possible to determine the effect of compensatory function hypertrophy by analyzing urophonographyic parameter under the same uroflow. The results of our experiment show that the effect of compensatory function hypertrophy in the early-stage obstruction of lower urinary tract, which is not detectible with uroflowmetry alone, can be assessed through urophonographic analysis.
