Early postkidney transplantation hypophosphatemia

Background: As hypophosphatemia is a common multifactorial problem of kidney transplantation (Tx), this research aimed at studying the frequency of posttransparent hypophosphatemia in the early postkidney Tx period and investigating the risk components associated with the situation. Materials and Methods: In this study, 50 renal transplant recipients on the day before (-1) and on days 10 (+10) and 30 (+30) days after kidney Tx were examined for the levels of serum phosphate (Pi). Levels of serum creatinine (Cr), Pi, 25-hydroxyvitamin D (25[OH] D), intact parathyroid hormone (iPTH) and fibroblast growth factor 23 (FGF-23), the 24 h urinary excretion of Pi and Cr, estimated glomerular filtration rate (eGFR), and the ratio of transport maximum of Pi (TMP) to eGFR (TMP/GFR) were evaluated on the same days. Results: Hypophosphatemia (serum Pi
