Abstract
A 59-year-old male started CAPD due to chronic renal failure of unknown etiology 8 years previously. The creatinine clearance of the patient was 8.3ml/min just before dialysis. His condition under dialysis was good and there were no severe complications, such as peritonitis, congestive heart failure or severe dehydration. The urine volume of the patient was maintained at over 1000ml/day, and the residual renal function was accounted for by 51.4% of creatinine clearance and 39.8% of total Kt/V. Although it is generally accepted that residual renal function is well-preserved for longer periods with CAPD than with hemodialysis, CAPD patients usually lose residual urine volume within several years. The course of this case was considered excellent because residual renal function is essential to maintain adequate dialysis by CAPD. Our findings indicated that early start of CAPD and prevention of severe complications which may exacerbate renal dysfunction are important to preserve residual renal function.
