Abstract |
Purpose : To investigate the changes of body fluid status after kidney transplantation (KT) and to find
out the associated factors.
Methods : Forty-five patients who had received KT were classified into hemodialysis (n=32), peritoneal
dialysis (n=5), and preemptive (n=8) groups by dialysis modality. %TBW, %ECF, %ICF, and edema
index which were examined by bioelectrical impedance analysis as well as clinical parameters were
prospectively measured before KT and 1st month, 3rd month, 6th month after KT.
Results : Before KT, there were no significant differences in all of the parameters listed above among
the three groups. Mean %TBW and %ICF were not different compared to those of before KT. In contrast,
mean %ECF markedly decreased within 1st month (before KT 21.13±3.04 L/kg, 1st month 20.03
±2.37 L/kg, 3rd month 19.61±2.18 L/kg, 6th month 18.32±5.02 L/kg: p=0.007, p<0.001, p=0.001,
respectively). Edema index also decreased from 1st month (1st month 0.354±0.014, 3rd month 0.352
±0.011, 6th month 0.348±0.014: p=0.016, p=0.012, respectively). Only edema index was higher at 1st
and 3rd month in hemodialysis group. Serum creatinine and 24 hour urine total protein were positively
correlated with %ECF at 1st and 3rd month, and with %TBW at 3rd month.
Conclusion : The recovery of body water distribution after KT starts with reduction of ECF within the
1st month. Serum creatinine and proteinuria are related to the recovery. No significant difference according
to dialysis modality was found. Further study with larger sample size is necessary to confirm
these findings. |
