Urography
These
pictures show intravenous urography. Note the lumbar vertebrae, the outlines
of the cavities (calyces) of the kidney and the ureters, as also the course of
the ureter. In about an hour’s time all the iodine compound will be in the
urinary bladder.
Key Points :
In intravenous urography, the medium is
injected through a vein.
It is too dilute in the bloodstream.
It is
‘concentrated’ in the urine by the kidneys.
This imaging
method also indicates that the kidney is functional!
