Abstract
Many children with severe urologic problems have been treated by urinary diversions, often after unsuccessful operations to correct the original pathology. Urinary diversion should be avoided when possible, since often it is accompanied by chronic infection and quality of life is less good than it could be. Most diversions can be prevented by use of other alternatives including reimplanting 1 ureter and transureteroureterostomy of the other, psoas hitch, wide mobilization and downward displacement of the kidney and ureter, use of bowel as ureter, cecal cystoplasty and early repair of complex pathology. Autotransplantation is probably seldom indicated in childhood.
