Urinary excretion of ganciclovir contributes to improvement of adenovirus-associated hemorrhagic cystitis after allogeneic bone marrow transplantation

A nine-yr-old girl developed AdV-associated HC after bone marrow transplantation. Intravenous GCV markedly reduced urinary AdV DNA loads and improved clinical findings. This appeared to result partly from a high concentration of GCV in urine. GCV may be effective for AdV-induced HC without definitive disseminated infection.
