Abstract EN
The ureter provides a way for urine to flow from the kidney to the bladder.
Peristalsis in the ureter partially forces the urine flow, along with hydrostatic pressure.
Ureteral diseases and a double J stent, which is commonly inserted in a ureteral stenosis or occlusion, disturb normal peristalsis.
Ineffective or no peristalsis could make the contour of the ureter a tube, a funnel, or a combination of the two.
In this study, we investigated urine flow in the abnormal situation.
We made three different, curved tubular, funnel-shaped, and undulated ureter models that were based on human anatomy.
A numerical analysis of the urine flow rate and pattern in the ureter was performed for a combination of the three different ureters, with and without a ureteral stenosis and with four different types of double J stents.
The three ureters showed a difference in urine flow rate and pattern.
Luminal flow rate was affected by ureter shape.
The side holes of a double J stent played a different role in detour, which depended on ureter geometry.
