Objective: Nonobstetric traumatic hematomas of the vulvar are rare. There are no consensus statements or best practice guidelines for the necessity or timing of surgical intervention. Methods: We retrospectively analysed the data of 33 cases of nonobstetric traumatic vulva hematoma. The outcome was to see whether different characteristics exist in surgical group compared to conservative management group. Results: Out of 33 cases, 20 (61%) cases were straddler injury and 11 (33%) cases were penetrating injury. Mean age was 25.7 year old and mean size of the hematoma was 8.4cm. Twenty fore cases underwent surgery mainly removal of the hematoma. Nine cases had conservative management such as ice bag apply, sitz bath, antibiotics or analgesia. The rate of deviation of the contralateral vulva due to hematoma was higher (54.2% versus 11.1%, p=0.047) and the mean size of hematoma was larger (9.5cm versus 5.2cm, p=0.004) in surgical group compared to conservative group. There was no statistical difference in the rate of urination difficulty, initial hemoglobin level, admission day, and visit number after discharge. Conclusion: Straddler and penetrating injury were the most common cause for nonobstetrical traumatic vulvar hematoma. Large hematoma (mean: 9.5cm) or deviation of the contralateral vulva due to hematoma had tendency to go on surgical management than conservative care.
