Hemorrhagic Cystitis: Treatment With Hyperbaric Oxygen Therapy in Patients With Acute Lymphoblastic Leukemia.

Hyperbaric oxygen therapy is a rare treatment modality for hemorrhagic cystitis (HC) following BK virus reactivation in the immunosuppressed population. Clinicians need to be aware of the etiology, preventive measures, complications, and various management techniques in HC while treating patients undergoing bone marrow transplantation. This study details the pathologic progression of HC in a patient with acute lymphoblastic leukemia harboring BK virus after cytotoxic induction chemotherapy and haploidentical marrow transplantation. A search of PubMed for literature published from 1973-2018 was conducted using keywords.
