Abstract
Objective
To measure the urea and creatinine kinetics in a pediatric population
Patients and Methods
In 19 children treated with peritoneal dialysis (PD) KT/V, urea and creatinine clearances (Ccr) were measured. Thirteen children were on continuous ambulatory peritoneal dialysis (CAPD) and 6 on nightly intermittent peritoneal dialysis (NIPD).
Results
Mean KT/V per week was 2.31 ±0.78 and mean creatinine clearance 74 ±47 L/week/1. 73 m2. There was no difference in dialytic KT/V between patients treated with CAPD and NIPD (1.75 ±0.21 vs 1.76 ±0.50). The correlation between KT/V urea and creatinine clearance was 0.9 (p<0.001). There was a clear relationship of these parameters with residual renal function, but not with age or blood urea level. A weak positive correlation was found with serum albumin and protein intake.
Conclusions
Mean KT/V in this patient group was higher than the values reported for most adult patient groups. Residual renal function considerably contributes to this high KT/V. It is not clearly defined which KT/ V should be aimed for, since criteria for adequate dialysis are multifactorially determined and therefore difficult to interpret.
