The paper deals with an introduction to the modelling of the bladder crash simulation. In this contribution we will consider that the whole urine-bladder system is kinematically excited. The wall of bladder featuring by non-linear elastic properties undertakes large strains. The urine is a Newtonian fluid, its flow is laminary and non-stationary. Solving this problem the finite element method is applied for the space discretization of continuums, the diference method for the time discretization and for the solution of a system of non-linear algebraic equations an iterative Newton-Raphson's method is then used.
