Randomised Trial Comparing Thermal Ablation With Adrenalectomy in the Treatment of Unilateral Asymmetric PA

The primary objective of WAVE is to test the hypothesis that thermal ablation (microwave or RFA) is non-inferior to surgery in the biochemical (and if so, in the clinical) cure of unilateral PA, according to the international consensus PASO criteria. Secondary objectives are to determine whether either intervention is superior to the other in relation to the following outcomes. Where no superiority of either intervention is established, non-inferiority of thermal ablation against adrenalectomy will be sought. * Frequency and severity of adverse events * Length of inpatient stay * Patient satisfaction * Quality of life * Return to activities of daily living An additional secondary objective in the thermal ablation group alone will be anatomical efficacy of ablation.
