5、small solute removal,the total(renal+peritoneal)Kt/V urea should not be less than 1.7 at any time(Evidence level A).That means,in anuric patients,peritoneal Kt/V urea has to be above 1.7.RECOMMENDATIONS 3In the presence of residual renal function,the contributions of renal and peritoneal clearances

6、may be added for practical purposes,although,as mentioned previously,renal and peritoneal clearances may not be truly additive(Opinion).Solute removal above this level should not be equated with“adequate dialysis.”RECOMMENDATIONS 3Knowledge of the transport characteristics of the patients peritoneal

7、 membrane by peritoneal equilibration test or other testsmay help to optimize the prescription to meet this target.RECOMMENDATIONS 4A separate target for creatinine clearance is not required in CAPD.In APD,due to a more variable relationship between urea and creatinine clearancean additional target

8、of 45 L/week/1.73 m2 for creatinine clearance is recommended(Evidence level C).RECOMMENDATIONS 5For patients who rely significantly on residual renal function to achieve the minimal target level of small solute clearance,residual renal function should be monitored regularly and at an appropriate fre
