RESUMO
OBJECTIVES: To investigate the prevalence of human papillomavirus (HPV) in the genital and urinary tract of men with urethritis. METHODS: Cell samples were collected from the penis, urethra and urine of 142 men with urethritis. A HPV test was performed on the samples using the modified GP5+/6+ polymerase chain reaction method, and the HPV genotype was determined using a HPV GenoArray test. RESULTS: Out of 142 urethritis patients, HPV was detected in 48% (68 cases), and high-risk HPV was found in 32% (46 cases) of patients, on their penis or in the urinary tract (urethra or urine). HPV was detected in 31% in the penis, 20% in the urethra and 24% in the urine, while high-risk HPV was identified in 23% in the penis, 12% in the urethra and 11% in the urine. Among the HPV-positive men, 66% had HPV infection in the urinary tract where the most common HPV types were HPV6, HPV16, HPV18 and HPV58. Single HPV-type infection was more frequently found in the urinary tract (89%) than in the penis (65%) (P < 0.05). CONCLUSIONS: Similar to the penis, the urinary tract represents a common HPV infection site in men with urethritis.
