Surface Representation of the Urinary Bladder and Bio-mechanical Analysis by Linear Dynamic Model uri icon


  • © 2020, Springer Nature Switzerland AG.The biomechanical characterization of Urinary Bladder is essential to create new therapeutic tools as artificial tissue replacement or electrical stimulators. In this paper, we applied a linear model, the so-called viscoelastic Voigt¿s model to calculate the viscosity and elasticity in three regions of a bladder under the experimental condition of tensile stresses. Additionally, we acquired the tridimensional surface of urinary bladders by a cloud of points that were processed in digital format. Viscosity and elasticity are represented on the surface reconstruction. Three bovine bladders were processed with an average sample viscosity of 89.33 × 10¿6 Ns/mm2 and average elasticity of 1.3 × 10¿3 N/mm, the isotropic condition was evaluated. The digital representation includes a cloud of points of 9 × 106 elements on average. These results are the base of a future computational simulation platform.
