By using a reductive perturbation method, a multi-dimensional modified Korteweg-de Vries equation has been derived to describe the propagation of a finite amplitude drift wave in a collisional plasma. When the viscous damping dominates the resistive growth, this equation allows a stationary shock solution. The profile of the shock wave tends to change from an oscillatory one to a monotonic one as the angle between the direction of propagation and the magnetic field increases. On the other hand, a stationary solution does not exist if the resistive growth is dominant over the viscous damping.
