The tendencies to phase-separation and stripe formation of the t\ensuremath-J model on planes and four-leg ladders have been here reexamined including hole hopping terms t^\ensuremath',t^\ensuremath'' beyond nearest-neighbor sites. The motivation for this study is the growing evidence that such terms are needed for a quantitative description of the cuprates. Using a variety of computational techniques it is concluded that the stripe tendencies considerably weaken when experimentally realistic t^\ensuremath'<0, t^\ensuremath''>0 for hole-doped cuprates are considered. However, a small t^\ensuremath'>0 actually enhances the stripe formation.
