Intravesical Instillation of Cidofovir in the Treatment of Hemorrhagic Cystitis Caused by Adenovirus Type 11 in a Bone Marrow Transplant Recipient

Hemorrhagic cystitis that occurs late after bone marrow transplantation (BMT) in BMT recipients is often associated with adenovirus or polyomavirus BK infections. Intravesical instillation of cidofovir in a BMT recipient with intractable hemorrhagic cystitis resulted in clinical improvement. Local cidofovir therapy for viral hemorrhagic cystitis could be an alternative to intravenous administration of cidofovir.
