Retrocaval Ureter with Proximal Hydroureteronephrosis Presenting as Flank Pain in a Child: A Rare Case Report with Review of Literature

Retrocaval ureter also referred to as pre-ureteral vena cava or circumcaval ureter is a rare congenital anomaly with the ureterpassing posterior to the inferior vena cava. Although it is a congenital anomaly, patients do not normally present with symptomsuntil the 3rd and 4th decades of life after a resulting hydronephrosis. We present the report of a 12-year-old male child with ahistory of right flank pain and associated right proximal hydroureteronephrosis. Diagnosis was confirmed with computerizedtomography urography, and an open surgical repair was done for the anomaly. The case is discussed here along with reviewof recent literature.
