Unscarred uterine rupture: a retrospective study

Background Uterine rupture is a catastrophic obstetrical emergency associated with significant feto-maternal morbidity and mortality. Many risk factors have been identified, as well as wide range of clinical presentations. The objective of the study was to analyse the incidence and predisposing factors of unscarred uterine rupture and to determine maternal and fetal outcome.

Methods Retrospective analysis of unscarred uterine rupture cases was conducted at the Department of Obstetrics and Gynecology, RIMS, Imphal from June 2012 to June 2014.

Results Our case series comprised of 13 cases with unscarred uterine rupture incidence of 0.057%. Out of these, 69.2% were unbooked cases. Majority of the cases were para 2-3. Most of the rupture (76.9%) occurred during 2nd stage of labour. The lower segment uterine rupture was the most common site of rupture (30.8%) Maternal and perinatal mortality were 30.8% and 53.8%, respectively. Sub-total hysterectomy done in 87.5% cases.

Conclusions Rupture uterus is a high risk category of patients. An unscarred uterus can undergo rupture even without risk factors. The patients with mismanaged labour, grand multiparas and obstructed prolonged labour must be managed by proper trained personnel and in tertiary care centre in order to avoid the morbidity or mortality.
