Secondary hyperparathyroidism is a common complication of end-stage renal disease and is associated with bone disease, vascular calcification, and increased mortality. Dialysis adequacy, measured by spKt/V and urea reduction ratio (URR), may influence phosphate control and parathyroid hormone levels.
This observational cross-sectional study will include adult patients with end-stage renal disease maintained on regular thrice-weekly hemodialysis for at least three months. Dialysis adequacy will be assessed by spKt/V and URR. Serum intact parathyroid hormone (iPTH) and mineral parameters will be measured.
