Retrocaval ureter: A case report and review of the literature.

Retrocaval ureter is a rare malformation. We report a case of right retrocaval ureter of type 1. The usual clinical manifestation being lumbar pain due to obstruction of the upper urinary tract, asymptomatic forms can also be encountered. Since the diagnosis was based on the CT-scan, the treatment was uncrossing with uretero-ureteral anastomosis by lumbotomy, with a satisfactory long-term result.
