Computational simulation of the flow dynamic field in a porous ureteric stent.

ABSTRACT: Ureteric stents are employed clinically to manage urinary obstructions or other pathological conditions. Stents made of porous and biodegradable materials have gained increasing interest, because of their excellent biocompatibility and the potential for overcoming the so-called 'forgotten stent syndrome'. However, there is very limited characterisation of their flow dynamic performance. In this study, a CFD model of the occluded and unoccluded urinary tract was developed to investigate the urinary flow dynamics in the presence of a porous ureteric stent. With increasing the permeability of the porous material (i.e., from 10^-18 to 10^-10 m²) both the total mass flow rate through the ureter and the average fluid velocity within the stent increased. In the unoc
