If the VCUG is normal and there is increased dilation of the renal pelvis during the follow-up, a diuretic renogram with DTPA or MAG3 or an excretory urography
should be performed, depending on the patient's age and renal maturity.

for acute flank pain," American Journal of Roentgenology, vol.
For a couple of decades, most series studied patients undergoing excretory urography
using high-osmolarity contrast media (HOCM).
The angle between the axis of the lower pole infundibular and ureteropelvic axis (angle 1), and the angle between lower pole infundibular axis and main axis of pelvis-ureteropelvic junction point (angle 2) are easily measured on standard excretory urography
. Determining the cut-off values of these angles and other significant predictors of success may help in detecting the renal anatomy and the patients who benefit from SWL.
A comparison of noncontrast computed tomography with excretory urography
in the assessment of acute flank pain.
Evaluation of the renal outline by excretory urography
CT is not as sensitive as excretory urography
in the detection of early urothelial mucosal changes, but is useful in determining the extent of renal and extrarenal spread of infection.
Objective: The objective of this study was to compare the three methods of preparation for excretory urography
with regards to image clarity: bowel preparation, together with dietary restriction, dietary restriction alone and no preparation at all.
Imaging findings of urinary tuberculosis on excretory urography
and computerized tomography.
For the most part, excretory urography
and barium gastrointestinal studies are rarely, if ever, utilized.
provides assessment of renal function.
Several studies have reported that 60% to 81% of patients who presented with kidney non-visualization by excretory urography
had invasive cancer.
