Unscarred Uterine Rupture: A Retrospective Analysis.

INTRODUCTION: Uterine rupture is a catastrophic obstetrical emergency associated with a significant feto-maternal morbidity and mortality. Many risk factors for uterine rupture, as well as a wide range of clinical presentations, have been identified.

OBJECTIVES: To analyze the frequency, predisposing factors, and maternal and fetal outcomes of uterine rupture.

METHODS: A retrospective analysis of cases of unscarred uterine rupture was conducted at the Department of Obstetrics and Gynecology, RIMS, Imphal from June 1, 2010 to June 30, 2012.

RESULTS: Our analysis comprised 13 cases. Of these, 30.8 % were booked cases. Most of the cases (46.2 %) were Para 2. Uterine rupture occurred at term in 10 cases. The rupture occurred due to mismanaged labor (30.8 %), the use of oxytocin (23 %), instrumental delivery (15.4 %), obstructed labor (15.4 %), induction by prostaglandin gel (7.7 %), and placenta percreta (7.7 %). Maternal deaths and perinatal deaths were 30.8 and 53.8 %, respectively. Sub-total hysterectomy was done in 8 cases and in 1 patient laparotomy with repair was performed.

CONCLUSION: Ruptured uterus causes a high risk in patients. An unscarred uterus can undergo rupture even without etiological or risk factors. The patients with mismanaged labor, grand multiparas, and obstructed prolonged labor must be managed by properly trained personnel at a tertiary care center in order to avoid the morbidity or mortality.
