The operation was performed from The London Clinic using a robot equipped with a 3D HD camera and four arms, all controlled through a console with a delay of only 0.06 seconds.
The console in the UK was connected to the robot in Gibraltar via fibre‑optic cables, with a backup 5G link.
A team in Gibraltar remained on standby in case the connection failed, but it held throughout the procedure.
The operation used the Toumai Robotic System, in a collaboration between The London Clinic and the Gibraltar Health Authority.
Dasgupta said: “This gives us the opportunity to treat patients in remote areas and smaller communities by literally being able to take the best surgeon anywhere.”
This was the first of two test cases, the second involving an unnamed 52‑year‑old man on 4 March, also in Gibraltar.
Dasgupta will perform the procedure again on 14 March, which will be live‑streamed to 20,000 world‑leading urological surgeons at the European Association of Urology congress.
He added: “I think it is very, very exciting, the humanitarian benefit is going to be significant.”
The NHS is prioritising local robotic‑assisted surgery, aiming for 500,000 robot‑supported operations a year by 2035, external.
