title: Chronic renal failure in children.
abstract: Seventy-seven children with chronic renal failure were examined at one hospital in the province of Quebec between 1970 and 1975; this represents an incidence of 2.5 per million population per year. The entities responsible for chronic renal failure were urinary tract malformation (in 36%), chronic glomerulonephritis (in 22%), congenital renal parenchymal malformation (in 21%) and hereditary nephropathy (in 13%). The evolution of chronic renal failure in children with either vesicoureteral reflux or a posterior urethral valve seemed to be related more to the initial severity of the disease than to the age at the time of diagnosis. Hence any screening program designed to detect kidney disease in schoolchildren would not prevent chronic renal failure, since at that age renal parenchymal damage seems to be irreversible. The manner in which chronic glomerulonephritis evolved depended on whether the nephrotic syndrome was present and on the type of histologic lesion. Children with congenital renal hypoplasia or dysplasia often presented with seizures due to hypertensive encephalopathy without obvious symptoms or signs of pre-existing renal disease. Among patients with familial nephropathy many of those with cystinosis underwent successful renal transplantation early in life.
