生理学的三次元腎盂・腎杯モデルを用いた自然排石を促す運動の検証

抄録

Urolithiasis is a disease in which calcium oxalate crystallizes in the urinary tract, and has a high recurrence rate. It is necessary to consider the burden on the body by surgical treatment, therefore, treatment methods that effectively promote spontaneous stone passage are required. In this study, to develop a working accelerated renal pelvis and calyx simulator, we visualized the orbit of a renal callus model by using a physiological 3D renal pelvis and calyx model and an acceleration motion experiment system. According to analysis from experiments, it was confirmed that the simulator is able to reproduce spontaneous stone passage similar to our experiment results. By establishing a spontaneous stone passage prediction simulator, it will be possible to devise a method to effectively promote spontaneous stone passage in patients. By reducing the morbidity of urinary lithiasis that requires surgery, it is expected to reduce the burden on patients and medical sites.
