Safety and Efficacy of Ultrasound Renal Denervation in Kidney Transplantation Patients With Uncontrolled Hypertension
Recruiting now · Not applicable
Conditions studied: Hypertension, Kidney Transplantation
In brief
This prospective, single-arm, interventional study is designed to assess the short-term and long-term safety and efficacy of bilateral ultrasound renal sympathetic denervation (RDN) of the native kidneys in renal transplant patients with uncontrolled hypertension. Objectives: * To assess the short-term and long-term changes in ambulatory and office blood pressure (BP) following native kidney RDN in renal transplant patients * To assess the long-term safety of native kidney RDN in renal transplant patients * To assess the short-term and long-term change in antihypertensive drug prescriptions following native kidney RDN in renal transplant patients * To assess the short-term and long-term change in adherence to antihypertensive drugs following native kidney RDN in renal transplant patients
