SECTION I: Measurement of renal function, when to refer and when to start dialysis
I.4 Measurement of residual renal function in HD
AbstractGuideline I.4
A. To assist in the standard reporting of residual renal function in HD:
- Residual renal function should be reported as GFR and expressed in ml/min/1.73 m2 as in pre-ESRD.
(Evidence level: C)
- GFR should be estimated as the mean of urea and creatinine clearance using urine collections as in CAPD and pre-ESRD.
(Evidence level: C)
- Because residual renal function may vary over the interdialytic period, the urine collections should be made over the entire interdialytic interval (usually 2 days).
(Evidence level: C)
- The mean blood urea and creatinine concentrations during the collection period should be estimated as the mean of the post-HD concentration immediately after dialysis (after rebound correction; see Appendix) and the pre-HD value immediately before the following dialysis.
(Evidence level: C)
- To convert GFR to Kt/V the Casino and Lopez [72] method should be used.
(Evidence level: C)
