Over last two decades ABPM has evolved from a research device to an established and valuable clinical tool for BP evaluation. More than 10 yrs ago ABPM was introduced to pediatrics and since that time, its importance has been increasing in the management of hypertension in children and adolescents. This review summarizes the information gathered from the studies of ABPM in adult and pediatric patients with renal transplants. We will review the importance of hypertension in this patient subset, discuss the advantage of ABPM over CBP and focus on specific abnormalities and clinical significance of ABPM in renal transplant recipients.
