Postoperative renal dysfunction in obstructive jaundice (OJ) patients has been associated with hypovolemia and depletion of the extracellular water compartment (ECW). The aim of the study was to evaluate the preoperative status of body compartments in OJ patients measured by two methods. In a prospective study 39 OJ patients (11 benign and 28 malignant obstructions) were investigated, with 15 healthy subjects used as a control group (CG). Bioelectrical impedance analysis (BIA) determinations and values derived from anthropometric measurements were used to assess body compartment status. The coefficient of variation of BIA was below 4% in both OJ and CG subjects. No differences were found in intracellular water. However total body water (TBW) and ECW were reduced in OJ patients (50.5 ± 4.6 vs. 56 ± 8% body weight, p= 0.05; and 21 ± 4.5 vs. 23.8 ± 2.5% body weight, p < 0.05, respectively). There were no differences between benign and malignant obstructions. Seventy four percent of OJ patients had an ECW volume below the mean ± 2 SD in the CG subjects. Anthropometric and BIA determinations correlated closely for TBW measurements in both CG ( r= 0.92, p < 0.001) and OJ patients ( r= 0.91, p < 0.001). Bland-Altman analysis also showed that for TBW the BIA was in agreement with anthropometry. In the present study, BIA offered a good correlation with anthropometric determinations and was a reliable method for body fluid disturbances assessment in jaundiced patients.
