In non-contrast images, a small stone is noted in the lower part of the left renal lodge.
After contrast media administration, the enhancement of both kidneys is non-uniform. In the secretory phase, moderate hydronephrosis without hydroureter is evident bilaterally; the left is more severe than the right causing delayed contrast excretion.

Moderate dilatation of the pelvicalyceal system is seen on both sides without ureter dilatation or ureteral stone.
A stone is also noted in the left kidney's lower part.
Case Discussion
Typical IVU and CT scan appearance of the bilateral ureteropelvic junction obstruction (UPJO).
