1. An x-ray made by pyelography, especially an intravenous pyelogram.
2. The procedure performed to produce such an x-ray.

pyelogram

[pī′əlōgram′]
Etymology: Gk, pyelos, pelvis, gramma, record
a radiographic picture of the kidneys and ureters taken after the IV or intraureteral injection of a radiopaque contrast medium. It shows the size and location of the kidneys, the outline of the ureters and bladder, the filling of the renal pelves, the patency of the urinary tract, and any cysts or tumors within the kidneys. Preparation for an IV pyelogram includes withholding of fluids for 8 hours and testing for sensitivity to the iodine in the contrast medium; people with known sensitivity are not tested lest anaphylaxis occur. Patients able to tolerate the contrast medium may feel warm and experience a salty taste when it is injected. Retrograde pyelograms, which demonstrate filling of the renal collecting structures, are taken after the contrast medium is injected into the ureters by means of catheters in a cystoscope introduced through the urethra into the bladder. Also called urogram.

Other tests may include a kidney and bladder ultrasound; an intravenous pyelogram (IVP), which involves injecting a liquid that can be seen on x-rays to highlight any obstructions in the kidney or bladder; or nuclear scans, tests that use radioactive material injected into a vein to reveal how well the kidneys and bladder are functioning.
In 7 kidneys, no pyelogram was obtained while delayed pyelogram was seen in 3 in one patient; the left kidney demonstrated a dense pyelogram.
Depending on your particular symptoms and history, your health care professional may perform a cystoscopy, in which a view instrument is inserted through the urethra into the bladder; a biopsy, in which tissue is removed for evaluation; an intravenous pyelogram or a CT urogram, in which an x-ray is taken of the urinary tract enhanced with a radioactive dye; a urodynamic test, in which the bladder is filled with liquid and then emptied to measure function; imaging using magnetic resonance imaging or computed tomography techniques.
The doctor also should do an imaging study of the urinary tract--typically with a computed tomography (CT) scan or an X-ray known as an intravenous pyelogram (IVP)--as well as a cystoscopy, in which a thin scope is inserted through the penis and urethra into the bladder to examine the lining and biopsy suspicious tissue.
Retrograde pyelogram demonstrated bilateral hydroureteronephrosis and bilateral extrinsic ureteral compression with medial deviation.
6 An infusion pyelogram is routinely ordered to determine a cause of dyspnea.
Q I HAVE to go for an IVP - intravenous pyelogram - to investigate a kidney problem.
After that, you may have a CA-125 blood test, abdominal or transvaginal ultrasound, a CAT scan, a lower GI series (barium enema) and/or an intravenous pyelogram.
The intravenous pyelogram provides high sensitivity and specificity for stones, but the procedure is not as cost-effective as CT, she said.
