[Cryotherapy for renal tumors: current status and contemporary developments]. / Crioterapia de tumores renales: estado actual y desarrollos contemporáneos.

ABSTRACT

The proportion of renal tumors found incidentally dramatically increased in the past decade. More than half of them were diagnosed in patients over 70 years of age, a population with high associated comorbidity. Nephron-sparing minimally invasive surgical procedures are aimed at treating patients with small renal tumors and multiple comorbidities. Cryotherapy stands out among all other ablative procedures because of its better mid-term oncological outcome. A non-systematic review of the literature on cryotherapy as a treatment for renal tumors was made, analyzing its indications, actual and future application techniques, results, and complications.
