Parathyroidectomy slows renal function decline in patients with primary hyperparathyroidism.

Area of Science:

• Nephrology
• Endocrinology
• Surgical Research

Background:

• Primary hyperparathyroidism (PHP) negatively impacts health, causing kidney stones and osteoporosis.
• The effect of parathyroidectomy on kidney function in PHP patients remains uncertain.

Purpose of the Study:

• To investigate the impact of parathyroidectomy on kidney function in patients with primary hyperparathyroidism.
• To assess changes in estimated glomerular filtration rate (eGFR) following parathyroidectomy.

Main Methods:

• Retrospective study of 27 primary hyperparathyroidism patients undergoing parathyroidectomy (2003-2017).
• Analysis of longitudinal eGFR changes using various metrics (e.g., annual decline rate, slope).
• Linear mixed-effect models applied to determine the effect of surgery on kidney function.

Main Results:

• Parathyroidectomy significantly slowed the rate of eGFR decline (from -2.73 to -1.67 mL/min/1.73 m²/year).
• No significant changes observed in proteinuria or eGFR distribution post-surgery.
• Greater benefits on kidney function were noted in patients younger than 65 and those without hypertension or chronic kidney disease.

Conclusions:

• Parathyroidectomy demonstrates a beneficial effect by slowing renal function decline in primary hyperparathyroidism patients.
• Findings suggest potential revision of surgical guidelines for primary hyperparathyroidism.
• Further large-scale controlled studies are needed to validate these results due to the small sample size.
