Development of Severe Hyperparathyroidism Despite Short-Term Renal Replacement Therapy

Background We occasionally experience cases of severe secondary hyperparathyroidism (SHPT) that require parathyroidectomy (PTX) despite undergoing short-term renal replacement therapy (RRT). Because the characteristics of such cases have never been discussed, we aimed to elucidate the pathophysiology of severe SHPT after short-term RRT by retrospectively analyzing clinical data.
