Hyperphosphatemia as a potential risk factor for arteriovenous fistula dysfunction: A retrospective study in hemodialysis patients.

ABSTRACT:

Background

The study investigates the relationship between Hyperphosphatemia and arteriovenous fistula dysfunction in patients undergoing maintenance hemodialysis.

Methods

Data were collected from patients who had their first arteriovenous fistula creation and regular maintenance hemodialysis between 2019 and 2023. Patients were divided into four groups based on serum phosphorus levels (<1.33 mmol/L, 1.33-1.61 mmol/L, 1.61-1.965 mmol/L, > 1.965 mmol/L). Statistical methods included Kaplan-Meier survival curves, Cox proportional hazards regression models, and Restricted Cubic Spline.

Results

The study included 239 patients. Kaplan-Meier survival curves showed that Hyperphosphatemia significantly correlated with arteriovenous fistula dysfunction (P = 0.0052). Cox univar
