Uterine dehiscence

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.

Clinical features

Generally the uterine dehiscence appears to be clinically occult and is not associated with any adverse maternal or perinatal outcomes.

Associations

Prognosis

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.
