[Reflux and obstructive nephropathy as a cause of renal failure in chronic dialysis children]

We carried out a retrospective analysis of medical files to evaluate causes of chronic renal failure in 80 children (M--49, F--31), age 1 month to 20 years) who started renal replacement therapy in the Department of Nephrology and Dialysis of the Polish Mothers Memorial Hospital in the years 1990-2007. In 28 children (35%) reflux and obstructive nephropathy was a cause of renal failure. In 5 children the disease was secondary to the neurogenic bladder. The incidence of these nephropathies in our population was constant in the analyzed years. In our group there were 2 neonates and 7 adolescent who were diagnosed with nephropathy as late as in the endstage phase. Boys with posterior urethral valve required renal replacement therapy earlier (146 +/- 55 months). We conclude that obstructive and reflux nephropathy are still the essential cause of end stage renal disease in children.
