Abstract
OBJECTIVE: To describe a case of solitary crossed renal ectopia that had been incidentally discovered in a healthy male with a previous history of spinal surgery. METHODS/ RESULTS: A 43-year-old male who had undergone two surgical procedures for severe scoliosis of the thoracic spine when he was 7 years of age, consulted for symptoms of unspecific urethritis that had just remitted. Abdominal ultrasound and excretory urography revealed a solitary crossed ectopia on the right side and the spinal x-ray showed congenital fusion of the cervical vertebrae (Klippel-Feil syndrome). CONCLUSIONS: Crossed ectopia of a solitary kidney is an exceedingly rare anomaly of the urinary tract (about 30 cases have been reported) combining renal agenesia of one side, contralateral displacement of the ureter draining the only kidney and agenesia or hypoplasia of the other ureter. It is frequently an incidental finding, although it may be associated with congenital spinal anomalies and even severe genital and anal anomalies.
