PLASMA VISCOSITY AS Α POSSIBLE DIAGNOSTIC TOOL IN DIFFERENTIATING BETWEEN UPPER AND LOWER URINARY TRACT INFECTIONS
Abstract
The aim οf this study was to determine the plasma viscosity levels in patients with urinary tract infection and to evaluate this variable as a possible diagnostic tool in differenfiating between upper and lower urinary tract infections. We measured plasma viscosity using a capillary viscometer at 25° C in 41 patients with urinary tract infection: 19 with upper and 21 patients with lower urinary tract infection. Plasma viscosity was also measured in 38 age matched healthy controls. The mean value ± 1SD of plasma viscosity in cP was: In patients with urinary tract infection: 1.565 ± 0.116. In patients with upper urinary tract infection: 1.565 ± 0.116 In patients with lower urinary tract infection: 1.698 ± 0.124 In controls: 1.516 ± 0.088 The plasma viscosity was significantly higher in patients with upper urinary tract infection compared to controls (p=0.000019). Patients with upper urinary tract infection had higher values of plasma viscosity than patients with lower urinary tract infection (p=0.01). The latter finding may be useful in indentifying the site οf urinary tract infection.References
