Case series of unscarred uterine rupture in primigravida

OBJECTIVE: To present a highly rare case series of uterine rupture in primigravida individuals with an unscarred uterus. CASE: The unscarred uterus in primigravida patients is supposed to be impervious to rupture, yet we have four cases of ruptured uterus in primigravida patients in our institute over a three-year period (2018-2021). In this case series, the ruptured uterus was discovered in primigravida women with premature labour, obstructed labour, instrumental delivery, and abruptio placentae. In the absence of previous surgery or multiparity, uterine rupture may go unnoticed, resulting in late diagnosis and considerable mortality and morbidity. All four cases required immediate resuscitation and laparotomy; uterine repair was performed in three cases, although a peripartum hysterectomy was needed in one. CONCLUSION: Rupture uterus can occur even in the unscarred uterus of primigravida patients and early diagnosis and timely management can prevent high maternal mortality and morbidity.
