The Hulthén-type potential is perturbed by adding the Yukawa potential. By applying a short-range approximation to the Schrödinger equation containing this model via standard method, the scattering state solutions and the corresponding phase shifts were obtained. Our numerical calculations and graphical solutions show the dependencies of scattering phase shifts on Yukawa potential constant A, asymptotic wave number k, screening parameter and angular momentum quantum number l.
