[The clinical significance of glitter-cells in the urine during urinary tract infection].
To clarify the relationship between glitter-cells and urine osmotic pressure, neutrophils were isolated from venous blood of 4 normal volunteers and incubated in urine specimens with different osmotic pressures. Glitter-cells were detected in the urine with 100-400 mOsm/l. The rate of glitter-cells in neutrophils incubated for 4 hours were significantly less than those incubated for 0 minute (p < 0.05). We clinically investigated the relationship between the presence of glitter-cells in fresh urine and the site of urinary tract infection (UTI) or organisms isolated from urine. Fresh urine samples were obtained from 95 patients (55 male and 40 female). Urine samples were examined for bacteriuria by the quantitative culture method, and significant bacteriuria was defined as more than 10(5)/ml of bacilli for midstream urine or as more than 10(4)/ml for urine collected by catheterization. Leukocytes and glitter-cells in the unspun and unstained urine were counted on a disposable slide using a counting chamber. Patients with upper UTI showed a significantly higher incidence of glitter-cells than patients with lower UTI (p < 0.05). Patients with glitter-cells had a significantly higher incidence of polymicrobial infections than those without glitter-cell (p < 0.05). These findings suggest that patients with glitter-cells in the urine show upper UTI (pyelonephritis) and polymicrobial infections.
