He is referring her for one of the two following procedures:
A catheter where radioactive liquid is placed to see if there is some returning into her kidneys
or
A radioactive liquid placed into her blood.
i dont understand either of them tbh but im glad they are doing investigations to determine why she keeps getting these UTIs, (well i not glad she will have to have one of the above treatments but you know what i mean)
