Outline of Final Research Achievements

There is not the method to evaluate an image about the effects of α 1 blocker which is the representative medicine of the internal use therapeutic drug for patients with prostatic hyperplasia objectively and quantitatively. Even if the thing with the effect of treatment is understood, the mechanism is unknown.Therefore we developed an urinary flow simulation system based on the information obtained from the endoscopic image and, in Chiba University urology department and an engineering graduate course, conducted clinical application for mechanism elucidation. In conducting urinary flow simulation, it led to energy analysis of the urinary flow, and it was recognized that energy efficiency increased in before and after therapy. We were able to confirm the differences using α 1 blocker having different site of action, too.
