heal.abstract	Taking into account the first localization corrections in theelectron-impurity self-energy we study the effect of non-magnetic impurities onunconventional superconductivity (SC) mediated by small-q electron-phononscattering. We show that when van Hove singularities are close to the Fermilevel making the electronic system anisotropic as in the high-$T_c$ oxides,both the d-wave and s-wave states are sensitive to non-magnetic	en
