Retrocaval ureter. Apropos of 6 cases]

The authors report six cases of retrocaval ureter discovered in quite various circumstances. A genital malformation associated to the retrocaval ureter was found in only one case. Five of our six patients were operated. Four of them underwent uncrossing of the ureter relative to the vena cava, and a patient underwent nephrectomy because her kidney was destroyed. The sixth patient was not operated because there was no impact on the excretory cavities of the kidney. This series and the review of the literature allow specifying the course of action for this pathology.
