An essentially normal ductogram (galactogram).
Observe the obstructive lesion near the lower end of the right ureter. On simultaneous retrograde examination, the lower margin of the obstructing lesion is clearly demarcated.
Intravenous pyelogram (IVP) (1 hour post-dye injection) showing right hydronephrosis, hydroureter, dilated renal pelvis and calvx.
Congenital UPJ Obstruction & Hydronephrosis Congenital utero-pelvic junction (UPJ) obstruction & hydronephrosis. This image demonstrates severe hydronephrosis of the right kidney. Retrograde pyelography demonstrates an obstruction at the UPJ. The obstruction...
Non-contrast CT for renal colic. Left Image: shows right-sided pelvicaliectasis relative to the left-sided renal collecting system. Right Image: shows calculus in the distal right ureter as the cause. [Courtesy of Dr. N. Jaffer]
