Abstract:

Objective To investigate the relationship between the residual renal function and nutritional state in maintenance dialysis patients. Methods Thirty chronic renal failure(CRF) patiants who received hemodialysis (HD) therapy and 30 CRF patients who received peritoneal dialysis (PD) therapy were enrolled. The residual renal function was calculated and the nutritional state was evaluated by SGA and examination index of biochemistry in the two groups, and then the relationship between the residual renal function and the nutritional state were analyzed. Results There were no significant difference of the residual renal function and the score of SGA between two groups pre-treatment (P＞0.05). The difference of the residual renal function between the two groups was significant after 6 months and 24 months’ treatment (P＜0.05). The difference of the SGA score were significant too (P＜0.01). The serum level of pre-albumin, transferrin and fibronectin decreased significantly (P＜0.01 or P＜0.05). The change of the serum albumin level was no significant (P＞0.05).There were correlations between the SGA score and the residual renal function in two groups(HD r = 0.849,PD r = 0.734 respectively).Conclusion There were close correlation between the nutritional stats residual renal function in maintenance dialysis patients. Patients whose residual renal function are preserved better have better nutritional state, which can improve their quality of life and survival rate. PD can preserve residual renal function better than HD.
