Living kidney donation represents the optimal renal replacement therapy, but recent data suggest an increased long-term renal risk for the donor. Here, we evaluated the risk for reduced estimated glomerular filtration rate (eGFR), death, and major cardiovascular events such as nonfatal myocardial infarction or cerebrovascular event including TIA (transient ischemic attack) and stroke in 225 donors, who underwent pre-donation examinations and live donor nephrectomy between 1985 and 2014 at our center. The median follow-up time was 8.7 years (1.0-29.1). In multivariate analysis, age and arterial hypertension at baseline were significantly associated with a higher risk of adverse renal outcomes, such as (1) eGFR <60 mL/min/1.73 m (age per year: HR (hazard ratio) 1.05, 95% confidence interval (CI) 1.03-1.08, hypertension: HR 2.25, 95% CI 1.22-3.98), (2) eGFR <60 mL/min/1.73 m and a decrease of ≥40% from baseline (age: HR 1.08, 95% CI 1.03-1.13, hypertension: HR 4.22, 95% CI 1.72-10.36), and (3) eGFR <45 mL/min/1.73 m (age: HR 1.12, 95% CI 1.05-1.20, hypertension: HR 5.06, 95% CI 1.49-17.22). In addition, eGFR at time of donation (per mL/min/1.73 m) was associated with a lower risk of (1) eGFR <60 mL/min/1.73 m (HR 0.98, 95% CI 0.97-1.00) and (2) eGFR <45 mL/min/1.73 m (HR 0.95, 95% CI 0.90-1.00). Age was the only significant predictor for death or major cardiovascular event (HR 1.08, 95% CI 1.01-1.16). In conclusion, arterial hypertension, lower eGFR, and age at the time of donation are strong predictors for adverse renal outcomes in living kidney donors.
