[30-year experience with operated-on and not-operated-on renal dystopy].

One hundred and thirty-eight patients with dystopic kidney were followed-up for 30 years. The operated and non-operated patients were considered separately. The condition manifested itself mostly after the age of 20. Under regular medical control, the condition can be treated by conservative methods. The possibility of an ectopic kidney should be thought of even when complaints are not typical or there are few symptoms.
