We derive generic relativistic hydrodynamical equations with dissipative effects from the underlying Boltzmann equation in a mechanical and systematic way on basis of so-called renormalization-group method. A macroscopic frame vector is introduced to specify which dynamics described. Our method so only few ansatz that our gives microscopic foundation available equations, also can be applied make reduction kinetic other than simple equation.
