They're about the same as the pros and cons for vaginal over cesarean with the only additional thing I can think of is that if you use cyrvidil or cytotec (sp?) to induce, you're much more likely to have uterine rupture due to the scar. With regular natural labor and even pitocin augmentation the risks are the same as with any other birth. Fyi, if your uterus ruptures you'll pretty much always have a c section afterwards, assuming the rupture wasn't bad enough to require a hysterectomy, which is rare.
