We study the structure of rings whose principal right ideals contain a sort of two-sided ideals, introducing {it right $pi$-duo} as a generalization of (weakly) right duo rings. Abelian $pi$-regular rings are $pi$-duo, which is compared with the fact that Abelian regular rings are duo. For a right $pi$-duo ring $R$, it is shown that every prime ideal of $R$ is maximal if and only if $R$ is a (strongly) $pi$-regular ring with $J(R)=N_*(R)$. This result may be helpful to develop several well-known results related to {it pm} rings (i.e., rings whose prime ideals are maximal). We also extend the right $pi$-duo property to several kinds of ring which have roles in ring theory.
