Sympathetic overactivity is frequently observed following renal transplantation (RTx), and post-transplant hypertension is a major contributing factor to graft failure and cardiovascular morbidity. This process is perpetuated by preservation of sympathetic afferent activity from the native non-functional kidneys, in the absence of efferent feedback to the renal transplant, which would otherwise modulate neurohumoral activity. We investigated the feasibility and efficacy of renal sympathetic denervation (RDN) in renal transplant recipients.

Patients (n = 18) with post-transplant hypertension were randomized 1:1 to receive RDN or medical treatment alone. The primary efficacy end point was change in office systolic blood pressure (SBP) and mean 24-h ambulatory blood pressure monitoring (ABPM) at 6 months. Safety end points were changes in renal function or …
