[Severe hematuria caused by radiation cystitis. Selective percutaneous embolization as an alternative therapy].

Post-radiotherapy cystitis is a high morbidity entity that involves difficult-to-treat haematurias and sometimes results in death. Percutaneous arterial embolization is an accepted approach for haemorrhages of pelvic origin. Selective, percutaneous embolization of both vesical arteries could be an alternative treatment to control severe haematurias caused by radiation. Presentation of our experience in two cases and proposal of this approach as a valid option in post-radiotherapy haemorrhagic cystitis.
