Renal cell carcinoma (RCC) is the most common type of kidney cancer in adults. Cryoablation therapy, which uses rapid freeze and thaw cycles to destroy diseased tissue, is the standard nephron-sparing option for RCC treatment. This case report suggests cryoablation as an effective therapy for hematuria in RCC. A 52-year-old male patient with Stage IV RCC presented to the ED with hematuria and flank pain. He was catheterized, and several blood clots were removed from the bladder. Embolization was considered, however renal angiography failed to demonstrate a tumoral blush and no target for embolization was identified. In lieu of continued large volume hematuria, cryoablation of the tumor was offered as a potential therapy. We describe a case of successful treatment of clinically significant hematuria in a patient with RCC with cryoablation.
