A robotic surgical technique which allows the accurate removal of cancerous tumours from the kidney has been performed for the first time in the UK at St George's Hospital. It uses an injected dye showing up as flourescent green, hence the firefly nickname.

The minimally invasive procedure used the new da Vinci robot.
