Uterine dehiscence is, usually, used to refer to the process of gradual myometrial rupture without a rupture of membranes. However, the term is used synonymously with uterine rupture by some authors. It is often described in the context of C-section scar where it is also termed an incisional dehiscence 5. Dehiscence can be partial or complete.
Interestingly classical transverse C/S scars are more likely to rupture before labour, whereas lower uterine segment C/S scars (LSCS) tend to rupture after labour.
Generally the uterine dehiscence appears to be clinically occult and is not associated with any adverse maternal or perinatal outcomes.

In a study it was suggested that preterm delivery and nonprogress of labor were independent risk factors for uterine scar dehiscence. In contrast, parity was found to have a protective effect against dehiscence 8.
