Over the past few years, I've been trying to track down a source for a statistic that I am fairly sure doesn't exist. More and more frequently I am hearing from women who've been told the risk of uterine rupture in VBAC is the same as the risk of uterine rupture for a first-time mom, or for an induced first-time mom.
Listen, I am all about putting the risk of rupture into perspective, but just as I hate it when the risks of cesareans are understated or misrepresented, I can't tolerate the same thing from my own camp. Every single source I have been able to find shows rupture risk in VBAC many times higher than risk with an unscarred uterus, regardless of parity, induction of labor, etc. I can not find a single reference in literature to a study showing a 1/2% to 1% risk of rupture in a non-VBAC labor. All I find are dead ends, and data confirming that a uterine scar is the single biggest risk factor for rupture.
I've asked multiple people in multiple forums for a source substantiating this claim, and no one has ever been able to provide one. So I figured I'd ask here too: does anyone have a source that will prove me wrong?
