Abstrakt: Living donor kidney transplant is the best treatment for end-stage kidney disease, posing minimal perioperative morbimortality for the donor, although long-term consequences are subject of debate if donor acceptance widens. We present a retrospective observational study analyzing clinical, demographic, and analytical variables throughout the follow-up period of 60 kidney donors whose procedures were performed between 1985 and 2021 at our hospital. Donors were divided according to their previous high blood pressure status, analyzing kidney function and other clinical parameters throughout follow-up. There were no statistically significant differences, although there was a trend toward a higher uric acid levels and lower high-density lipoprotein cholesterol in predonation patients with hypertension, not yielding an excess of end-stage kidney disease between groups at the end of the follow-up. We also analyzed the evolution of estimated glomerular filtration rate (eGFR), dividing patients into tertiles, which resulted in none of the parameters associating a higher rate of progression. All donors had an eGFR >71 mL/min/1.73 m 2 at the time of donation. Over time, a decline in eGFR <60 mL/min/m/1.73 m 2 was observed in 26 patients (53.6%), measured by Chronic Kidney Disease Epidemiology Collaboration estimation and in 55.4% of the total (31 patients) by Modification of Diet in Renal Disease. At our center, kidney donors with adequate predonation eGFR, although presenting a reduction in postnephrectomy eGFR, remain stable afterward, with none of them reaching an eGFR <30 mL/min/1.73 m 2 . We found no differences in the impact of high blood pressure on long-term eGFR, nor predictive factors influencing the rate of eGFR decline. Studies with larger number of patients are needed to confirm these results.
