  In this paper we prove the existence of positive solutions of the following
singular quasilinear Schr\"{o}dinger equations at critical growth
\begin{eqnarray*} -\Delta u-\lambda
c(x)u-\kappa\alpha(\Delta(|u|^{2\alpha}))|u|^{2\alpha-2}u =
|u|^{q-2}u+|u|^{2^*-2}u,\quad u\in{D^{1,2}(\mathbb{R}}^N), \end{eqnarray*} via
variational methods, where $\lambda\geq0$, $0<\alpha<1/2$, $2<q<2^*$. It is
interesting that we do not need to add a weight function to control
$|u|^{q-2}u$.
