There is a calculus with coronal height up to 10 mm in the right side ureteropelvic junction with pronounced hydronephrosis upstream.
Bilateral fat containing inguinal hernia is noted.
Calcified focus on the right side of the pelvic cavity adjacent to the posterior bladder wall is seen.
Case Discussion
The case illustrates the non-contrast MDCT feature of ureteropelvic junction obstruction (UPJO) due to an impacted calculus within the junction. A calculus in UPJ must be carefully managed.
