Recall that evaluation must include contrasted urogram images with cystoscopy or cystoscopy with retrograde pyelogram
. Patients with LS are at increased risk of renal pelvis and ureteral cancers, not bladder cancer as is more common in the general population.

A left retrograde pyelogram
(RGP) showed gross upper pole caliectasis with pelvic staghorn calculus.
To identify the cause of hematuria, your doctor may order various tests, such as urinalysis, blood tests, ultrasound, intravenous pyelogram
or CT urogram, or may examine your bladder with a cystoscope.
Contrast in the calyceal system is the pyelogram
, which depends not only on the distension of the pelvi- calyceal system but also on the concentration of the contrast medium within it.
The kidneys, ureters, and bladder can also be x-rayed as contrast dye passes through them to detect blockages (intravenous pyelogram
We would admit a child with a UTI to the hospital, start antimicrobial therapy, do an intravenous pyelogram
after a negative urine culture, and keep the child on antibiotics for a month until the follow-up vesicoureterogram (VCUG).
4) has largely replaced the intravenous pyelogram
They would be discharged after a cystoscopy and retrograde pyelogram
had displaced the sloughed papillae and relieved the obstruction.
Radiology procedures that use IV dye include coronary angiography, computed tomography scan, and intravenous pyelogram
(Merten et al., 2004).
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.
