인체 기반 요관 모델에서의 뇨 흐름에 대한 유체구조 연동해석

초록

The ureter serves to transfer urine from the kidney to the bladder. If stenosis or obstruction occurs in the ureter, clinicians must insert a double J stent (DJS) in the upper urinary system from the renal pelvis to the bladder. When a double J stent is inserted in the ureter, peristaltic movement is reduced or eliminated. Therefore, it is necessary to accurately understand urine flow through the ureter and to predict the changes that may occur when a stent is inserted. Movement of the DJS occurred such that the flow rate of urine inside the stent increased. Observation of DJS deformation revealed that the amount of deformation in the curl portion was moved slightly. Furthermore, the DJS exhibited a large amount of deformation in the middle portion of the ureter. The pushing or colliding of the stenosis with the DJS may further exacerbate side effects.
