Bilateral renal and ureteral calculi

Case contributed by Shervin Sharifkashani


Bilateral flank pain and nausea.

Patient Data

Age: 35 years
Gender: Male

Multiple calculi up to 4-6 mm in kidneys, a calculus with coronal height up to 7 mm in left side ureter middle segment, and a few calculi up to 5 mm in right side ureter distal segment extended within right side UVJ with upstream hydroureteronephrosis more severe in the left side are seen.

Case Discussion

The case illustrates non-contrast MDCT features of bilateral concomitant renal and ureteral calculi, which is relatively uncommon. The major cause of ureteral obstruction is ureteral calculi. Multiple and recurrent renal calculi can cause chronic renal disease in the long term.
