Puerperal uterine inversion is an uncommon but life threatening obstetrical emergency. A 26-year-old woman, para six, was referred from a peripheral hospital seven days after delivery, with a mass protruding per vaginum. Complete uterine inversion had occurred after delivery of baby and placenta. She was resuscitated and her genital infection was treated. She had a vaginal hysterectomy upon request. Her postoperative recovery was uneventful. Poor management of the third stage of labour is a common cause of uterine inversion. Early replacement of the inverted uterus is important to prevent further complications.
