BackgroundThe increase of live kidney donation (LKD) demands that we scrutinize its long-term consequences. Socialized medicine in Sweden has allowed us to survey long-term consequences of LKD with a high response rate.MethodsBetween 1974 and 2008, 455 LKDs were performed; 28 donors were deceased and 14 had moved abroad at the time of the survey. Of the remaining 413, 96% agreed to participate in a retrospective study with laboratory testing and answering a questionnaire.ResultsMean age at donation was 49 ± 10 years, and the mean time since nephrectomy was 11 ± 7 years (range 1-33). No death was of renal cause. S-creatinine at follow-up was 93 ± 18 μmol/L, 28% had treated hypertension, of whom only 52% had BP <140/90. Eleven per cent had spot microalbuminuria, and 1% were diagnosed with diabetes mellitus. Seventy-one per cent had check-ups at least every second year, but 14% had no check-ups. Eighty per cent would be willing to donate again if it were possible, and only 3% regretted the donation.ConclusionRenal function is well preserved in the long term after donation, no case of end-stage renal disease was identified, and a large majority of our donors would donate again if it were possible. Although rates of microalbuminuria and hypertension were at expected levels, a significant number of donors demonstrated elevated blood pressure levels and inadequate antihypertensive treatment. A relatively large number of donors did not receive regular check-ups. Both of these issues demonstrate the need for a better-structured lifelong follow-up.
