Spin Hall effect in a two-dimensional electron gas with uniform Dresselhaus and random Rashba spin-orbit interactions is considered theoretically. Using Kubo formalism we derive some analytical formula for the spin Hall conductivity. It is shown that the contribution due to randomly fluctuating Rashba field disappears in the limit of strong Dresselhaus coupling.
