However, the technique is ...

Urea clearance (Kt/V urea), adjusted for total body water (TBW) using the Watson formula (TBW(Watson)), is widely used to guide peritoneal dialysis (PD) prescription and to ensure dialysis adequacy. The impact of body composition on the determination of TBW(Watson) is well established, but the effect of hydration and nutrition status on TBW(Watson) is not understood. We therefore studied the ef...
