There is pronounced hydronephrosis and ballooned pelvis in the left kidney but no dilated ureter which is most compatible with ureteropelvic junction obstruction (UPJO). Increased size of the left kidney is also seen.
The case illustrates the non-contrast MDCT features of ureteropelvic junction obstruction (UPJO) and pronounced hydronephrosis upstream.
