Fluid overload and renal function in children after living-donor renal transplantation: a single-center retrospective analysis

Background We aimed to compare renal function after kidney transplantation in children who were treated with higher vs. lower fluid volumes. Methods A retrospective analysis of 81 living-donor renal transplantation pediatric patients was performed between the years 2007 and 2018. We analyzed associa...

Description
Summary:Background We aimed to compare renal function after kidney transplantation in children who were treated with higher vs. lower fluid volumes. Methods A retrospective analysis of 81 living-donor renal transplantation pediatric patients was performed between the years 2007 and 2018. We analyzed associations of the decrease in serum creatinine (delta creatinine) with fluid balance, central venous pressure (CVP), pulmonary congestion, mean arterial pressure (MAP), and MAP-CVP percentiles in the first 3 postoperative days. After correcting creatinine for fluid overload, we also assessed associations of these variables with the above parameters. Finally, we evaluated the association between delta creatinine and estimated glomerular filtration rate (eGFR) at 3 months follow-up. Results Both delta creatinine and delta-corrected creatinine were found to be associated with pulmonary congestion on the second and third postoperative days ( p  80 ml/kg, and greater improvement in renal function. Impact There is no consensus regarding the optimal fluid treatment after pediatric renal transplantation. In our cohort, indices of fluid overload were associated with better renal function immediately after the transplantation and 3 months thereafter. Fluid overload after living-donor renal transplantation in children may have short- and long-term benefits on renal function.
