[The urological complications of fused kidneys in childhood].

From January 1972 to August 1991 twenty-eight children with renal fusion were observed in the Department of Pediatric Surgery of Regional Hospital of Vicenza. Of the 28 children nine, (32%), had associated congenital malformations. Nineteen children with renal fusion showed twenty major urological complications (68%). Four were treated conservatively and 16 surgically. Results have been excellent in all the cases. Renal fusion often are associated with congenital malformations and fused units are often involved by pathological process. Renal surgery in fusion is conditioned by the renal position degree of malrotation of the renal pelvis and by the abnormal blood supply. The surgical approach must be in children conservative and the long term results are very often good.
