title: Progression to end-stage renal disease in children with obstructive uropathy.
abstract: The course of 54 patients (35 boys and 19 girls) with end-stage renal disease resulting from obstructive uropathy was reviewed. The mean age at the initial sign of obstructive uropathy was 3.5 years. Twenty-two patients (41%) manifested evidence of obstructive uropathy during the first year of life. The mean age at the time of onset of ESRD (dialysis) was 12.2 years and was similar in boys and girls. The mean time interval between the first sign of obstructive uropathy and the initiation of dialysis was nine years. Fourteen patients operated upon at less than one year of age developed ESRD one to 20 years (mean ten years) following their initial surgery. Progression to ESRD occurred despite appropriate surgical management, including corrective as well as diversionary urologic procedures. However, because the patients were selectively referred for care of ESRD, no assessment of the incidence of ESRD caused by obstructive uropathy was possible. The data indicate that prolonged follow-up periods are necessary to assess the ultimate outcome of renal function in young patients with obstructive uropathy. Despite early intervention and intact renal function for many years during childhood, progression to ESRD may occur.
