title: [Crossed renal ectopy without fusion. Case report].
abstract: We report a case of crossed renal ectopia without fusion in a 30-year-old patient who had consulted for unspecific abdominal pain and micturition syndrome from an unstable detrusor and urethra. We underscore the rarity of this malformation in comparison with crossed fused renal ectopia, a condition reported to account for almost 90% of crossed renal ectopias. The embryogenic hypotheses that have been put forward relative to this malformation are presented, and the urinary and other system malformations frequently associated with this condition are discussed.
