Relation of bioimpedance measured hypervolemia with short and long term outcomes in kidney transplant patients

Abstract

There are very few data in literature on prevalence and consequences of hypervolemia in kidney transplant recipients. The objective of our study was to evaluate association of repeated bioimpedance parameters (fluid overload) on immediate delayed graft function, hypertension control and kidney function one and three years after kidney transplantation. An observational, prospective, 3 years one-center cohort study included 46 cadaveric kidney recipients transplanted in Hospital of Lithuanin University of Health Sciences during the year 2015. For evaluation of volemia status bioimpedance analysis (BIA) was performed 2 times for each patient: two hours before kidney transplantation and on discharge from the hospital after kidney transplantation. After transplantation data about blood pressure, creatinine concentration | were collected on the same day as bioimpedance analysis was performed. Volemia status was evaluated according to extracellular/total body water ratio in bioimpedance analysis - hypervolemia considered when ratio was >39%. [...].
