Residual renal function (RRF) may contribute significantly to the total dialysis prescription. Conventional quantitation of RRF in hemodialysis (HD) patients is measured by urea clearance and requires a 24-hour urine collection which is often difficult to perform and inaccurate. The renal clearance of Use of iohexol to quantify hemodialysis delivered and residual renal function. This result agrees with data from anuric patients for whom extrarenal iohexol clearance was measured between 2 hemodialysis sessions. 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. Determination of residual renal function with iohexol clearance in hemodialysis patients.

Iohexol clearance in hemodialysis

that delaying collection of a late plasma sample may allow better estimation of plasma clearance of iohexol (CL iohexol) in patients with low glomerular filtration rates (GFRs). Iohexol is a non-ionic, low-osmolar, X-ray contrast medium with a molecular weight of 821 Daltons and it is mainly eliminated from plasma in its intact form by glomerular filtration (extrarenal clearance ≈2 ml/min) and it is often stated to be effectively removed by HD [7, 8].

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.

Received for publication November 11, 1997 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. The iohexol mass removed by dialysis and the residual renal function (if any) equals the difference of the two estimates of body iohexol, see eq.4. Significantly more iohexol was removed by the longer dialysis, +32% see Figure 1b and Table 1.

Classically, urea (molecular wt 5 60) is used to determine the urea reduction ratio (URR) or clearance, based on volume of distribution (Kt/V). These methods are subject to many errors.
