pyelogram การใช้

Where a CT scan is unavailable, an intravenous pyelogram may be performed to help confirm the diagnosis of urolithiasis.
In IVP, the contrast agent is given contraindicated for some reason, a retrograde pyelogram, with the contrast flowing upstream, can be done instead.
There are also available markers to indicate positioning of the body e . g . supine, or as to time when performing procedures such as an Intravenous pyelogram.
Retrograde pyelography is generally done when an intravenous excretory study ( intravenous pyelogram or contrast CT scan ) cannot be done because of renal disease or allergy to intravenous contrast.
A "'Gas pyelogram "'is a pyelogram in which the kidneys, renal pelvis and ureters are filled with gas, and have a radiolucent appearance.
