• Nongonococcal urethritis

• Patients with NGU (50% of cases) have a longer incubation period compared to those with GU, and the onset of either dysuria or, less commonly, a mucopurulent discharge, is subacute. Patients with NGU are much more likely to be asymptomatic than patients with GU.

• NGU is caused by C trachomatis (15-55% of cases), U urealyticum (40-60% of cases), M hominis (5-10% of cases), and T vaginalis (<5%>Ureaplasma and Mycoplasma species. The causative organism cannot be identified in most patients with NGU.

• Rare cases may be related to lymphogranuloma venereum, herpes simplex, syphilis, mycobacteria, or urinary tract infection with urethral stricture. Other rare but reported causes of NGU include anaerobes, adenovirus, cytomegalovirus, and streptococcus.

• Urethritis following catheterization occurs in 2-20% of patients practicing intermittent catheterization and is 10 times more likely to occur with latex catheters than with silicone catheters.
