Bladder haemorrhage is common and sometimes life-threatening. Management options include bladder irrigation and supportive transfusion, intravesical instillation, endourological intervention, and surgical intervention which has poor success and high morbidity rates. Percutaneous arterial embolisation offers another minimally invasive option. We report two patients with severe haemorrhagic cystitis treated with superselective embolisation of bilateral superior vesical arteries. The technique is safe and effective for achieving immediate control of refractory bladder haemorrhage. The long-term efficacy of the procedure requires further investigation.
