Management of non-obstetric traumatic vulvar haematoma: a retrospective review of 33 cases.

The cases of non-obstetric traumatic vulvar haematomas are rare, and there is a lack of consensus statements for the necessity of surgical intervention. We retrospectively analysed the data of 33 cases (mean age: 25.7 years) of non-obstetric traumatic vulvar haematoma (mean haematoma size: 8.4 cm). Women who underwent surgery (surgery group) were compared to those who received conservative management (conservative group). Twenty-four patients underwent surgery; most cases were of haematoma removal and primary closure. Nine patients received conservative management, such as ice bag application, antibiotics, or analgesia. The rate of deviation of the contralateral vulva because of haematoma was higher (54.2% versus 11.1%,  = .047) and the mean haematoma size was larger (9.5 versus 5.2 cm,  = .004) in the surgical than in the conservative group. While conservative management affects cases of minor vulvar haematoma, surgical evacuation of haematoma can be performed in cases of large haematoma (mean size: 9.5 cm), severe pain, distorted vulvar anatomy, and invisible urethral opening for indwelling urinary catheter.IMPACT STATEMENT Cases of non-obstetric traumatic vulvar haematomas are rare. There are no consensus statements for the necessity of surgical intervention. The study showed that surgical evacuation of haematoma can be performed in cases of large haematoma (mean size: 9.5 cm), severe pain, distorted vulvar anatomy, and invisible urethral opening for indwelling urinary catheter. Moreover, surgical management could hasten recovery. The results of this study can be used in counselling non-obstetric traumatic vulvar haematomas. Further research is needed to confirm these findings.
