Cell population of urinary leucocytes of 22 patients (intestine group) who underwent operations using intestinal segments for the urinary tract was compared with that of 26 complicated UTI patients without surgical intervention (control group). Eosinophils were recognized in 15.5 per cent of urinary leucocytes of the intestine group. However, in the control group, urine eosinophils were recognized only in 0.15 per cent. Although in sterile urines of the intestine group eosinophils were recognized in 30.8 per cent, in infected urines, the percentage of eosinophils decreased. Conversely, the percentage of neutrophils increased to 91.9 per cent. These findings suggest that neutrophils play an important role in infected urines of the intestine group as in urines of the control group. Significant differences were found in the values of urinary secretory IgA, IgG, IgM and urinary osmolarity. To evaluate the influence of these differences on the activity of phagocytosis of urinary leucocytes, the activity of phagocytosis of polymorphonuclear leucocytes (PMN), isolated from the peripheral blood, was investigated in immersion in urines of both groups. The mean rate of phagocytosis of E. coli in urines of both groups showed no statistically significant differences. However, urinary osmolarity of the intestine group was within the suitable range for phagocytosis and the activity of phagocytosis in urine was correlated with the value of IgG, which suggests that IgG has the opsonic effect. In contrast, the activity of phagocytosis in urine of the control group was strongly correlated with the value of urinary osmolarity. The growth of Providencia, Streptococcus, P. aeruginosa, whose frequency of isolation from urine of both groups was different in our previous study, and E. coli was studied in urine of the two groups. No significant difference in the growth of all bacteria was found, however. This finding suggests that the difference in the frequency of isolation of these bacteria from urine possibly depends on the adhesion of bacteria to intestinal epithelium.
