Large bladder flap haematoma following a caesarean section associated with right hydroureteronephrosis: A case report and a mini‑review of the literature

Post-caesarean section bladder flap haematoma is a rare postpartum complication. There are currently no specific treatment protocols, at least to the best of our knowledge. In general, the failure of conservative treatment with antibiotics requires the re-operation and surgical drainage of the haematoma. The present study describes the case of a primiparous pregnant woman who, at 40 weeks of pregnancy, delivered by caesarean section. On the 3rd post-operative day, the puerperant, haemodynamically stable, developed febrile infection. During the evaluation, the presence of bladder flap haematoma associated with moderate right hydroureteronephrosis was found. The failure of conservative management led to the decision to perform a re-laparotomy 1 week later. During the surgery, a large bladder flap haematoma was found with a retroperitoneal extension into the right parametrium. The surgical drainage of the haematoma and thorough haemostasis in the area of the vesicouterine pouch was performed. The patient was discharged from the clinic on the 5th post-operative day following the re-operation. After 2 weeks, an ultrasound revealed the complete repair of the lesions in the vesicouterine pouch and the right kidney. In the present study, a brief review of literature is also provided regarding the diagnostic and therapeutic management of patients with post-caesarean section bladder flap hematoma.
