Abstract

Among current epidemics, chronic kidney disease (CKD) is accompanied with high morbidity and mortality rates inherently associated with the thriving comorbidities of hypertension and cardiovascular disease. In this mutually reinforcing triad, adequate control of high blood pressure emerges as extremely important for decreasing patients’ complication rates and prolonging life expectancy. However, hypertension control in this particular group of patients is often proven an arduous task, presenting high rates of resistance. Sympathetic nervous system (SNS) overactivity is implicated not only in the pathophysiological basis of difficult-to-treat hypertension, but also in the development and progression of renal disease, thus rendering SNS a prime therapeutic target in CKD. As renal nerve ablation (RNA) is finding its place among other invasive procedures in the cardiovascular arena, the potential therapeutic impact of this innovative treatment modality is gradually expanding from resistant hypertension to other high blood pressure-related clinical conditions like CKD. Encouraging results of clinical trials testing efficacy and safety of renal nerve ablation in resistant hypertensives provide the opportunity to apply the procedure in other subgroups of hypertensive patients. Available data regarding renal function of study participants suggest the safe implementation of RNA in patients with renal disease, but both unexplored benefits as well as potential hazards should be taken into account and critically evaluated. While renal denervation has been tested in selected cases of patients with renal disease, the results of large, multicenter trials evaluating the effects of this procedure on large cohorts of patients with CKD are eagerly anticipated.
