GFR decreased to 63% of its baseline levels just after donation but improved 10% during the first year. PTH levels increased on D1, returning to baseline levels on D14, while FGF23 remained higher than baseline over the first year. LKD had a significant reduction of serum phosphate on D1, which returned to baseline levels on D180. A higher fractional excretion of phosphate (FEP) was noted since D14. After 10 years of donation, 20 LKD presented a sustained reduction in GFR (74.8\u2009\u00b1\u200914mL\/min). There was a return to baseline in serum FGF23 [21.8 (18\u201330) pg\/mL] and FEP, accompanied by an increase in serum calcium. PTH remained elevated (57.9\u2009\u00b1\u200918 pg\/mL), whereas serum calcitriol and Klotho were lower than before the donation.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>The abrupt decline in kidney mass is associated with an increase in PTH and FGF23 that is not explained by phosphate retention.
