Structural renal abnormalities are one of the most common causes of hypertension in children. In this study, it was aimed to compare office blood pressure (OBP) and ambulatory blood pressure monitoring  (ABPM) values in children with structural renal abnormalities. The data from patients with structural renal abnormalities who performed ABPM were evaluated in this study. It was investigated whether there were significant differences between OBP and ABPM values. The paired t-test was used to determine the significance of the differences between OBP and ABPM values. The factors affecting the differences between office and ambulatory blood pressure values were investigated using linear regression analysis. The OBP values were significantly higher than nighttime systolic blood pressure (SBP) and diastolic blood pressure (DBP) (p<0.01). The OBP values were positively correlated with all differences (p<0.05). Age and body mass index were positively associated with OBP–nighttime SBP difference (p = 0.001, p = 0.015, respectively). Serum blood urea nitrogen level was positively associated with OBP–nighttime DBP and OBP–24h DBP differences (β = 0.220,  p = 0.033, β = 0.205,  p =  0.045, respectively). There was a negative correlation between glomerul filtration rate and OBP–nighttime SBP difference (β = -0.05,  p = 0.01). The performing of ABPM and the evaluation of the differences between office and ambulatory blood pressure is very important in the early recognition of the hypertension in children with structural renal anomaly.
