Retrocaval ureter in children. Case report and bibliographic review.

Objective: Retrocaval ureter is a rare disease which is due to a abnormal development of the inferior cava vein. It usually presents with ureteral obstruction, and surgery is needed for symptomatic cases.

Methods: We present a case of retrocaval ureter and a revision of the literature.

Results: A 9 year-old boy who had consulted for macroscopic hematuria. The intravenous urography (IVU) suggested the diagnosis of retrocaval right ureter, which is confirmed by magnetic resonance imaging (MR). Make us resection of the retrocaval segment and relocation of the ureter anterior to the inferior vena cava. Follow-up IVU showed good resolution of hydronephrosis.

Conclusions: Retrocaval ureter is a rare disease, with easy diagnostic and effective treatment. Other associated anomalies could be associated.
