after calculating the quantity of ultrafiltrate ( about 13 l ) containing an amount of waste products of metabolism equivalent to 24-h urine elimination , we determined in vitro the amount of sorbent required to eliminate these waste products from the ultrafiltrate ( e.g. , 20 g of urea/day ) and we have evaluated the quantities of other substances which must be replaced using a tailored diet .
