Hypertension in renal transplant recipients is common. Overall in adults the prevalence of hypertension after kidney transplantation is estimated to be 50–80% while in children it ranges from 47 to 82%. Cardiovascular morbidity mortality and shortened allograft survival are important consequences of inadequate control of hypertension. Donor and recipient factors acute and chronic allograft injury and immunosuppressive medications may each explain some of the pathogenesis of post-transplant hypertension. As observed in other patient cohorts renal artery stenosis and adrenal causes of hypertension may be important contributing factors.
