| Outline of Final Research Achievements |
We designed and produce an equipment for an ureterolith test using a real or model ureter stent and estimated effect of small pores geometry of the stent on ureterolith formation in comparison with CFD analysis of flow in the stents. As a result, it was found that somewhat difference was confirmed in ureterolith formation though a flow field in the stent was independent on the pore shapes in such low Reynold’s number condition.
We also estimated behavior of a laser induced bubble for a laser lithotripsy. A bubble induced by a fiber-laser near a solid wall was observed by a high speed video camera under various laser irradiation conditions. As a result, characteristic bubble collapse behaviors and impacts toward a solid wall were obtained.
