Whole bladder mechanics during filling.

In addition to molecular and cellular properties, elemental and whole bladder properties are important to the function of the bladder during filling. The bladder pressure volume filling relation is dependent on all aspects of bladder tissue. Elemental mechanics properties include elasticity, viscoelasticity, and plastic deformation of bladder tissue. Whole bladder properties include bladder shape, mass, and distension. This paper reviews work on mathematical model aimed at determining the effect of whole bladder properties on bladder filling mechanics and outlines directions for the future.
