Retrocaval ureter

  1. 1. A 14 year old male presented with a three months history of right flank pain that was of sudden onset and initially colicky but had become constant.
  2. 2.  Full blood count, urinalysis and blood urea and creatinine were normal.  No evidence of hematuria.
  3. 3.  Abdominal ultrasonography revealed a right hydronephrosis.  An intravenous pyelography showed delayed function of the right kidney and subsequently a right hydronephrosis and hydroureter of the proximal ureter with non-visualization of the rest of the right ureter.
  4. 4. Diagnosis?
  5. 5. Also known as “circumcaval ureter” Ureter courses posterior to the inferior vena cava Incidence  0.07%  Male to female ratio of  3:1
  6. 6. Abnormality in embryogenesis of IVC  Results from abnormal persistence of right subcardinal vein positioned ventral to ureter in the definitive IVC  Developing right ureter courses behind and medial to the IVC
  7. 7. Symptoms of right ureteral obstruction Right flank pain Hydronephrosis Pylonephritis fever
  8. 8.  Right ureter’s course swings medially over pedicle of L3/4  Passes behind IVC  Then exits anteriorly between IVC and aorta returning to its normal position  Produces varying degrees of proximal hydroureteronephrosis
  9. 9.  Abdominal ultrasoundAbdominal ultrasound demonstrates hydronephrosis.  IVUIVU does not demonstrate the middle and distal ureter requiring a retrograde ureteropyelogram to demonstrate the ureter and hence confirm the diagnosis.
  10. 10.  Spiral CTSpiral CT define the ureter and inferior vena cava anomalies obviating the need for a retrograde ureteropyelogram and is considered an investigation of choice.  MRIMRI demonstrate the course of a pre-ureteral vena cava a more detailed and less invasive imaging modality, without exposure to radiation
