title: How to differentiate between ectopia and displacement in patient with crossed kidney.
abstract: A patient is described in whom a crossed kidney was found. There was doubt whether this was due to displacement or ectopia of the kidney. A review of literature on this subject gave no answer to our problem. Considering the embryologic development of crossed ectopic kidney and the mechanism of kidney displacement across the midline we found a simple method by which the diagnosis can be made.
