Hemorrhagic cystitis due to adenovirus infection following bone marrow transplantation.

Immunocompromised patients are at significant risk for infection with adenovirus. We report 3 cases of hemorrhagic cystitis in patients following bone marrow transplantation. Of the patients 2 had positive viral urine cultures and 1 had positive stool culture but negative urine culture and biopsy proved viral cystitis. Diagnosis of adenovirus should be considered when gross hematuria follows bone marrow transplantation even when urine culture is negative for adenovirus.
