Kidney transplants from living donors have increased, but few studies have examined the long-term risks of live donor nephrectomy. This is the first study to report the blood pressure (BP) changes associated with cardiovascular disease and linked to chronic kidney disease (CKD) 1 year after live donor nephrectomy. This study examined a prospective cohort of patients who underwent donor nephrectomy between March 1, 2006, and December 31, 2016, at the Severance Hospital, Seoul, South Korea. CKD was defined as a glomerular filtration rate (GFR) of < 60 mL/min/1.73m2. Patients with a history of hypertension or CKD or an estimated GFR < 60 mL/min/1.73m2 were excluded; those examined after 1 year post-nephrectomy were included in the study population. Among 420 patients who underwent donor nephrectomy, 137 (32.6%) developed a first-time onset of a GFR < 60 mL/min/1.73m2 by the first year after surgery. After propensity score–matching the age, systolic BP (P <.001) and pulse pressure (P =.006) were significantly associated with the groups with newly developed CKD. Systolic BP and pulse pressure decreased significantly at 1 year after donor nephrectomy. These differences decreased after donor nephrectomy, possibly lowering the risk of cardiovascular disease.
