Objective: To observe effect of combination of TCM-WM with high colonic lavement for delaying renal failure. Methods: 98 cases of renal failure at compensatory phase were randomly divided into a treatment group treated with high colonic lavement

twice each week. 2 hours each time

and a control group treated with oral administration of coated aldehyde oxystarch

10g each time

thrice each day

3 months constituting one course. Results: After lavenment. symptoms were improved

deceaseing velosity of the clearance rate of endogenous creatinine in blood and urine slowed lowered

renal survival rate of kidney increased

and the interval of dialasis and other replacement therapy obviously postponed in the treatment group as compared with that before treatment and the control group. Conclusion: The high colonic lavement has obvious therapeutiv effect in delaying renal failure velosity with a smaller stimulation to the stomach and smal intestine. It is an effective way for conservation treatment of renal failure.
