Role of Renal Venous Oxygen Pressure for Renal Function Monitoring After Related Living-Donor Kidney Transplantation: Cohort Study.

Background: Monitoring of renal function after kidney transplantation (KT) is performed by measuring serum creatinine (SCr), urine volumes (UV), and glomerular filtration rate (GFR). Other methods based on oxygen metabolism, such as the renal venous oxygen pressure (PO), may be useful. The aim of this study was to explore the correlation between PO and SCr, UV, and GFR 5 days after KT (SCr5, UV5, and GFR5, respectively).
