Ectopia renale semplice

Renal ectopy is a rare congenital malformation, related to an abnornal migration of the kidney from the sacral to lumbar region. Three possibilities are present: absent migration (pelvic ectopia), excessive (intrathoracic ectopia), or to the opposite side (crossed ectopia). During the last 3 years in the Paediatric Surgery Department of University of Siena 7 cases of simple renal ectopy have been observed. Five patients were female and two were male. Associated anomalies were present in three patients: two presented cardiological malformation, one was polimalformated (anal atresia with rectum-urethral fistula, bilateral clubfoot, microphtalmia of left eye, large coloboma of righ eye, IAD, IVD, ectopic horseshoe kidney). One patient, who ha renal function reduced to 10%, was operated, while the remaining six were under clinical control.
