Retrocaval ureter

Case contributed by Dr Saeed Soltany Hosn


An asymptomatic male came for routine medical fitness sonography which demonstrated hydronephrosis (not shown here). CT scan was performed for further evaluation.

Patient Data

Age: 30 years
Gender: Male

CT scan demonstrates right-sided hydronephrosis and hydroureter because the right ureter passes behind the inferior vena cava at the level of lower endplate of L3 vertebra. The ureter exits medially between the cava and the aorta to return to its normal position. The distal third of the ureter has normal diameter.

Case Discussion

Findings are in keeping with a retrocaval ureter.

The CT study demonstrates also ring artefacts
