Two patients with stage D transitional cell carcinoma of the kidney presented with recurrent massive hematuria. Both had prompt cessation of bleeding following renal infarction. Another patient had malignant hypercalcemia related to metastatic renal cell carcinoma and became normocalcemic after renal infarction. Angiographic renal infarction offers a rational alternative to conventional therapy in the management of these 2 problems.
