204 CHAPTER 8 Figure 1. Kidney function of living kidney donors before and after kidney donation. (A) At start of the study (POD-pre), creatinine levels were significantly higher in the control group. Postoperatively, a trend towards lower levels of creatinine were observed in the CCPR-group. (B) Taking POD-1 as cut-off value, relative creatinine clearance was significantly improved in the CCPR- group at POD2, POD3 and POMo1. (C) Absolute glomerular filtration rate did not significantly differ between the groups. (D) Relative eGFR showed significant improvement in the CCPR group at POD3. (E) Serum urea levels were significantly lower in the CPPR-group on POD1 and remained so in the first two postoperative days. Values are depicted as median ± interquartile range. CCPR = combined calorie and protein restriction; POD = postoperative day; POMo = postoperative month; eGFR = estimated glomerular filtration rate using the CKD-EPI formula. *=significant values.
