• Resumen

  • Current computational models of ureter are not usually based on physiological behavior of anatomical structures. For this reason, we propose a new simplified model of ureteral flow to simulate a peristalsis bolus on the distal section of the ureter. This model uses a closed ureter that generates the urinary bolus with an expansive force applied in its wall. To analyse this, a computational FSI simulation is proposed to recreate the peristalsis movement of the ureter in its distal section. These preliminary results will be improved in future works to build a more complex model and to analyse the effects in the urine flow of a new design of a half-length ureteral stent.
