The increasing number of small renal tumours being detected had led to the recent development of nephron-sparing surgery. Cryotherapy has become an important treatment option for renal tumours. The recent advances in cryosurgery have occurred as a result of the recent of the introduction of open-type MRI.

The therapy allows minimising damage to the tissue around the frozen area.
