Objective: The purpose of this study was to find out the aetiology of end-stage renal failure (ESRF) in children in Jordan.
Subjects and methods: This was a multicentre retrospective study at five participating hospitals. Data collection included medical record review for age, gender, aetiology of ESRF, modality of renal replacement therapy (RRT) and outcome. End-stage renal failure was defined as estimated glomerular filtration rate < 15 mL/min/1.73m2.
Results: There were 275 children with ESRF: 131males and 144 females. The most common causes of ESRF in children were congenital anomalies of the kidney and urinary tract (CAKUT), 45.8%, heredofamilial disorders, 23.2% and glomerulopathies, 26.2%. Neurogenic bladder, reflux nephropathy and posterior urethral valve accounted for 16.8%, 12.7% and 4.0%, respectively. Amongst the heredofamilial disorders, primary oxalosis and cystic disease accounted for 8.0% and 7.2% of the aetiologies of ESRF, respectively. Focal segmental glomerulosclerosis was the most common histological type amongst the glomerulopathies (10.2%), followed by mesangiocapillary glomerulonephritis (4.7%) and chronic glomerulonephritis (3.0%). The aetiology was unknown in 4% of the cases. The modality of dialysis included isolated peritoneal dialysis (PD) in 30.9%, isolated haemodialysis (HD) in 49.1%, alternating peritoneal and haemodialysis in 9.1%, transplanted in 8.7% and conservative treatment in 1.8%. Death occurred in 57.3% of PD patients versus 34.4% in HD patients.
Conclusions: This is the first report on the aetiology of ESRF in children in Jordan. The most common aetiologies of ESRF were CAKUT 45.8%, heredofamilial disorders 23.2% and glomerulopathies 22.9%.
