Introduction: Neonatal hypertension (HT) is an emerging challenge for neonatologists and pediatricians around the world. The prevalence of renal causes of neonatal hypertension due to congenital renal anomalies and malformations including obstructive uropathy and cystic kidney disease is not well estimated up till now. Early diagnosis of congenital renal anomalies is the corner stone of good prognosis and better outcome.
Aim of the study: To determine the prevalence of neonatal renal hypertension in apparently healthy term neonates discharged in the first 48 h of life from two university hospitals.
Methods: Two thousand apparently healthy appropriate for gestational age (AGA) term newborns had blood pressure (BP) measurements using the oscillometric technique All results of blood pressure were compared to estimated blood pressure values in percentile curves generated by Dionne et al. 
Results:  There were 29 of 2000 (1.45%) screened newborns diagnosed as having systemic hypertension, our study showed that  renal anomalies were the main causes of neonatal systemic hypertension. It represent (93.1 %) of total causes in our study, [with pelviureteric junction (PUJ) Obstruction (31%), polycystic kidney (24.1%), nephrocalcinosis (13.7 %), unilateral renal dysplasia (10.3%), renal hypoplasia (3.4%), unilateral multi cystic kidney (3.4%)].The remaining cases (6.9%) were due to aortic coarctation. No endocrinal cases was diagnosed in our study.
Conclusion: This study showed that renal anomalies were the most common causes of neonatal systemic hypertension in apparently healthy term newborns. Beside that this study provided normative BP values for healthy full term AGA newborns in the first 48h of life. These values can be used in the evaluation of BP in newborns.
