This article describes a new minimally invasive treatment for men with recurrent cancer post radiotherapy and localised prostate cancer utilising argon and helium gases. Cryosurgery utilises high pressure argon and helium gas linked by a computer-controlled delivery system to cryoneedles which are introduced through the perineum into the prostate gland. Transrectal ultrasound allows accurate placement of the needles. Temperature needles are used to protect the sphincter muscle and rectum.
