The purpose of this study was to determine whether iohexol (Io; molecular wt = 821) could be used instead of urea and provide better information as well as middle molecule clearance data. METHODS: Ten hemodialysis (HD) patients were evaluated.
First studies in humans documenting biochemical properties and pharmacokinetics parameters (15-18) showed that iohexol is excreted unchanged in urine and its renal clearance is almost identical to 51 Cr-EDTA clearance. The reliability of GFR determination by iohexol plasma clearance was demonstrated a few years later by Krutzén et al. .
67, nr. 5, s. 811. Thus, we believe that properly performed plasma iohexol clearance using long sampling time is a suitable technique for estimating residual kidney function in patients receiving hemodialysis. The established method based on urine collection and blood sampling is less suited for everyday clinical practice. These methods are subject to many errors. The purpose of this study was to determine whether iohexol (Io; molecular wt = 821) could be used instead of urea and provide better information as well as middle molecule clearance data.
We read with interest the recent article by Shafi et al1 reporting discrepancies between plasma and urinary clearance of iohexol in dialysis patients. This could jeopardize estimation of residual kidney function when incremental dialysis is used. The URR and iohexol reduction ratio (IoRR) were also different (0.63+/-0.02 vs. 0.69+/-0.02; P < 0.002) with a urea but not Io rebound (URR30 min 0.59+/-0.02, P < 0.05). Calculated urea clearance (C(urea)), 247+/-21 ml/min, significantly overestimated DDQ C(urea) (157+/-10 ml/min P < 0.001).
We measured between-dialysis 2-sample plasma iohexol clearance for which the last sample was taken 44 hours after in- Iohexol transmembrane clearance during modeled continuous renal replacement therapy.

The patient told us that he had good diuresis and therefore a measurement of kidney function was performed. A 48-hour iohexol clearance measurement showed
We aimed to characterize iohexol, molecular weight 821 Da, clearance during continuous hemofiltration (CH) and continuous hemodialysis (CHD). METHODS: Using an in vitro model, iohexol sieving coefficients (SC) and saturation coefficients (SA) were determined with the M100 membrane at ultrafiltration/dialysate rates of 1, 2, 3, 4, and 6 l/h.
