Residual renal function (RRF) is an important determinant of mortality and morbidity in patients undergoing dialysis.

残余肾功能(RRF)是影响透析患者存活率的重要因素。

The main way to prevent malnutrition in CAPD patients is to timely adjust the prescripition of dialysis based on their RRF.

根据RRF下降程度，及时调整透析剂量及方案，是预防CAPD患者营养不良发生的最主要手段。

Conclusion: RRF is closely related with the adequacy of peritoneal dialysis and may affect the nutritional condition of CAPD patients.

结论：RRF与腹膜透析充分性密切相关，并影响腹透患者的营养状况。

Positive control of the blood pressure, selection of appropriate anticoagulant and protection of RRF have important clinical significance.

积极控制血压、选用恰当的抗凝方法以及保护RRF有着重要的临床意义。

Objective The residual renal function (RRF) in maintenance hemodialysis patients was determined to assess its impact on patients' nutritional status.

目的：通过测定维持性血透患者的残余肾功能(RRF)和营养指标，了解规律透析后rrf变化及RRF对营养状况的影响。
