A case of a large inoperable hypernephroma in a 69-year-old man is presented. Recurrent life-threatening hematuria was controlled successfully by transcatheter embolization and infarction of the tumor using a tissue adhesive called isobutyl 2-cyanoacrylate. The patient remained without hematuria for 18 months until death from extensive metastatic disease. The advantages and disadvantages of tissue adhesive as an embolization material are discussed.
