Historical Perspective
The urithritis was first described by Albert Neisser, a german doctor in 1879.[1]
Classification
Based on etiology of urethritis, it is classified in to two main group, infectious and non-infectious. The non-infectious causes further divided to gonococcal and non-gonococcal.
Pathophysiology
Urethritis is a genital tract inflammation mostly due to infectious causes. Its pathogenesis depends on underlying pathogen.
- N. gonorrhoeae is usually transmitted via the genital tract to the human host
- Following attachment to host cell which is mediated by pili, gonococci become engulfed in a process known as parasite-directed endocytosis. This organism will survive inside the vacuoles and replicate.[2]
- Chlamydia trachomatis is the most common pathogen among non gonorrheal causes.
- Infectious process starts by cell surface attachment and phagocytosis by host cell. This pathogen survives inside the cell by debilitating the cellular lysosomes and replicate as elementary bodies (the infective form of pathogen).[3][4]
Causes
Urethritis may be caused by either infectious or non infectious causes. Infectious causes are divided to gonorrheal and non-gonorrheal.[5] Non-gonorrheal pathogens are the most common cause of urethritis, Chlamydia trachomatis on top of them.[6][5][7]
