Chronic Kidney Disease, Hypertension, Renal Transplantation, Sympathetic Activity
Conditions
Brief summary
The study is aiming to document the safety and effectiveness of renal denervation in patients after renal transplantation with hypertension. Catheter-based renal denervation will be performed using CE marked, percutaneous Symplicity catheter.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Safety and efficacy of renal denervation in patients after renal transplantation | Baseline to 6 months | Effect on blood pressure including office, ABPM, and home-based measurements. Number of adverse events. Changes of antihypertensive medications. Effects on renal function assessed with glomerular filtration rate. Renovascular safety (renal artery stenosis) assessed by duplex ultrasound. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Effect of renal denervation in patients after renal transplantation on different organ systems. | Baseline to 6 month | Effects on sympathetic activity assessed by heart rate variability and post extrasystolic potentiation. Glucose metabolism and insulin resistance (fasting and during oGTT). Hospitalization rates (eg. hypertensive emergencies, heart failure, etc). |
