RESUMO
Objective To investigate the effects of colon dialysis on chronic renal failure(CRF).Methods 120 patients with CRF were randomly divided into two groups and they were given the same conventional therapy including alimentary control,blood pressure control,etc.The A group (colon dialysis group,n=60) was given colon dialysis,the B group (conventional therapy group,n=60) was given conventional therapy for 4 weeks.The serum creatinine(SCr),urea nitrogen,24 h proteinuria were observed in two groups.The therapeutic effects of colon dialysis were assessed by the changes of SCr.Results The colon dialysis and conventional therapy can decrease the SCr from (363.97±82.34) μmol/L to (280.87±87.52) μmol/L and (371.73±87.46) μmol/L to (339.90±68.59) μmol/L respectively.The former was more effective than the latter.The effects of colon dialysis in the renal function compensation stage and decompensation stage were more effective than in renal failure stage but no difference was detected between the former stages.Conclusions The colon dialysis has certain effects to CRF,especially to those with serum creatinine ＜443 μmol/L can get more benefit.
