title: Ureteritis cystica after treatment of cyclophosphamide-induced hemorrhagic cystitis.
abstract: A case is presented in which ureteritis cystica developed following formalin instillation for treatment of cyclophosphamide-induced hemorrhagic cystitis. It is not known whether this complication, not previously reported, is a result of the cyclophosphamide, the formalin, or a combination of both. Patients being considered for formalin instillation should be studied by cystography for evaluation of vesicoureteral reflux. Alternative methods to formalin instillation should be considered in patients with reflux.
