This not a very common problem, and is usually discovered as a result of investigation after passing blood in the urine. Full staging will be carried out, so that the extent of the problem can be established, and the usual treatment will involve removing the whole of the ureter, together with the kidney above it, usually through a combination of laparoscopic and open surgery. The main problem with the condition is that subsequent checks of the bladder and other ureter will be needed, to catch any further tumours that may occur at a very early stage.
