Rupture of the uterus

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine

Background:

• Uterine rupture is a critical obstetric emergency with significant maternal and fetal morbidity and mortality.
• Understanding the etiological factors and outcomes is crucial for improving management strategies.

Purpose of the Study:

• To determine the frequency of uterine rupture.
• To identify the etiological factors associated with uterine rupture in both scarred and unscarred uteri.
• To compare maternal and fetal outcomes in different etiological groups.

Main Methods:

• Retrospective analysis of 50 cases of uterine rupture over a 4-year period.
• Categorization of cases based on the presence or absence of a previous uterine scar.
• Identification and comparison of common etiological factors and outcomes.

Main Results:

• The overall frequency of uterine rupture was 1 per 89.9 deliveries.
• Thirty-four cases involved previously scarred uteri, while 16 occurred in unscarred uteri.
• Common causes in unscarred uteri included cephalopelvic disproportion, grand multiparity, and mismanagement by traditional birth attendants.
• In previously scarred uteri, causes included cephalopelvic disproportion, forceps delivery, grand multiparity, and prolonged first stage of labor.
• The unscarred uterus group exhibited high maternal and fetal mortality (81.6%).

Conclusions:

• Uterine rupture poses a significant risk, particularly in women with unscarred uteri, where mortality rates are alarmingly high.
• Distinct etiological factors contribute to uterine rupture in scarred versus unscarred uteri, necessitating tailored management approaches.
• Addressing factors like cephalopelvic disproportion and improving the management of labor, especially by traditional birth attendants, is vital to reduce uterine rupture incidence and improve outcomes.
