Modern science opens up new potentials for the effective treatment of complex diseases using minimally invasive techniques. One of the obvious achievements of recent years is cryoablation - technology of local freezing of tissues, allowing to create a precision zone of tumor cell death in renal cancer and prostate cancer. The literature review presents historical information, highlighting the main stages in the development of cryosurgery since the XIX century. The analysis of domestic and foreign literature has shown that in urological practice cryoablation has been widely used. Based on the literature data, indications, contraindications and complications of cryoablation in renal cancer and prostate cancer, as well as long-term results of treatment are discussed. Cryoablation has been used actively abroad; in the Russia, method is developing, but without a doubt, will be actively introduced in medical practice.
