Cross-Renal Ectopia about a Case

Crossed renal ectopia is a rare congenital anomaly, it was described by WILMER in 1938 [1], implies that one of the two kidneys sits on the contralateral side, the ureter of the ectopic kidney crosses the midline to meet in the bladder on the opposite side, the existence of a parenchymal fusion is frequent (85 to 90%). This anomaly is most often asymptomatic and discovered incidentally. We report the observation of a 21-year-old woman with a G1P1V1A0 obstetrical history (ATCD), presenting cross renal ectopia discovered fortuitously following pain in the right flank associated with palpation of an abdominal mass and to review the literature.
