Objectives: Our goal was to determine the short-term effects of donor nephrectomy on the cardiovascular system and to gain a better understanding of the recently recognized long-term increased risk of endstage renal disease and cardiovascular mortality. Materials and Methods: Living kidney donors who underwent donor nephrectomy between January 2010 and January 2015 at the Hacettepe University Transplantation Unit were retrospectively screened. Echocardiographic parameters, kidney volumes, and renal functions before nephrectomy were compared with measurements after nephrectomy. Flowmediated dilatation values of living kidney donors were compared with healthy individuals. Results: The study included 73 female and 31 male living kidney donors with a mean age of 46.1 ± 10.8 years. In the comparative analysis of donors versus 35 healthy individuals, the changes in flow-mediated dilatation were 12.3 ± 5.7% and 15.4 ± 6.3%, respectively (P = .016). In the comparative analysis of preoperative versus the last visit transthoracic echocardiographic results, left ventricular end-systolic and end-diastolic diameters decreased and left ventricular posterior wall thickness and septum thickness increased (P = .025, P = .002, P = .026, and P = .019, respectively). Conclusions: Nephrectomy may cause several hemodynamic changes in living kidney donors, which may exacerbate cardiovascular risks in this population.
