The upper urinary tract in neurogenic bladders without diversion---a ten-year follow-up.

Within the first 5 years of life, 50% of children with neurogenic bladders developed subvesical obstruction. Children with neurogenic bladders who did not developed subvesical obstruction (according to group I) up to the age of 5 years are not likely to develop obstruction unit they reach the age of 10 years. Children who do develop such an obstruction before the age of 5 years are possible candidates for urinary diversion.
