[Study of urethritis in males using Papanicolaou smear].
Sexual pathogens, cell types and morphologic alterations of urethral epithelial cells were investigated by means of the Papanicolaou smear in 110 heterosexual men. Seventy-five patients with urethritis were included: 17 (22.6%) with gonococcal urethritis (GU) and 58 (77.3%) with non-gonococcal urethritis (NGU). Thirty-five males without symptoms or signs of urethritis comprised the control group. An increase in epithelial cell dissociation was observed in patients with urethritis. Non-specific inflammatory changes were statistically more common in patients with urethritis than in controls, and more severe in GU (65%) than in NGU (15.5%). Nuclear atypia was a common finding (43.5%) in infections due to C. trachomatis. Mucus was associated with the presence of urethritis although no differences regarding etiology were found. No polimorphonuclear neutrophils were observed in the exudate of three patients (5%) with NGU. There was a statistically significant presence of lymphocytes in patients with urethritis, particularly in GU (45%), more frequent than in NGU (15.5%). Erythrocytes were also significantly more frequent in urethritis, with a greater proportion in GU (94%) than in NGU (64%). Plasma cells, eosinophils, and histiocytes were only observed in a few patients with urethritis. The Papanicolaou smear had a sensitivity of 47% and a specificity of 90% in Chlamydia trachomatis infections.
