About this trial
This study aims to clarify whether surgical treatment of persistent hyperparathyroidism after kidney transplantation offers clinically meaningful benefits compared with a conservative treatment strategy.
Kidney transplant recipients (\>6 mo after transplantation) with persistent hyperparathyroidism (elevated PTH and either hypercalcemia or hypophosphatemia) will be randomized in a 1:1 ratio to either subtotal parathyroidectomy or conservative management according to standard clinical practice. The study is conducted as an open-label, randomized controlled pilot trial with a 12-month follow-up period.
Outcomes include bone density, physical function, quality of life and symptom burden.
