| Summary: | There are very few published reports on the causes of chronic kidney disease (CKD) in Egyptian children. We reviewed the records of 1018 (males 56.7%, age ranged from 1 to 19 years) Egyptian patients suffering from CKD and followed-up at the pediatric nephrology units (outpatient clinics and dialysis units) of 11 universities over a period of two years. The mean of the estimated glomerular filtration rate was 12.5 mL/min/1.73 m 2 . Children with CKD stage I and stage II comprised 4.4% of the studied group, while those with stage III, IV and V comprised 19.7%, 18.3% and 57.6%, respectively. The most common single cause of CKD was obstructive uropathy (21.7%), followed by primary glomerulonephritis (15.3%), reflux/urinary tract infection (14.6%), aplasia/hypoplasia (9.8%) and familial/metabolic diseases (6.8%); unknown causes accounted for 20.6% of the cases. Of the 587 patients who had reached end-stage renal disease, 93.5% was treated with hemodialysis and only 6.5% were treated with peritoneal dialysis.
