Abstract:

Objective To investigate the diagnosis significance of urinary leukocyte count and bacterium count for male gonococcal urethritis. Methods A total of 140 urine specimens for male patients with urethritis were determined for urinary leukocyte count and bacterium count by UF-1000i automatic urine analyzer, which the samples were then concentrated and smeared. The specimens of Gram-negative diplococcus were confirmed as the cases of gonococcal urethritis. The evaluation parameters such as sensitivity and specificity were counted statistically to diagnose male gonococcal urethritis. Results The sensitivity was 92.0%, the specificity was 80.0%, the positive predictive value was 71.9%, the negative predictive value was 94.7%, and the area under receiver operating characteristic (ROC) curve was 0.824 for diagnosing gonococcal urethritis, when urinary leukocyte count was ≥300/μL, and bacterium count was ≤300/μL. Conclusions Urinary leukocyte count and bacterium count show significance in the diagnosis of male gonococcal urethritis.
