title: [Crossed ectopic kidney. Apropos of 3 cases].
abstract: Three cases of crossed renal ectopia are presented, one with and two without fusion which were discovered by chance as the result of urological investigations and which are more frequent in men than in women and on the left side. The authors stress the importance of urography and retrograde pyelography as vital methods of diagnosis. They comment the topic and make a review of the literature.
