Urethral wall ulcer is syphilis caused by it

Urethral wall ulcers may be caused by syphilis, but there may be other causes.

Syphilis is one of the causes of urethral wall ulcers. Syphilis is a sexually transmitted disease caused by Treponema pallidum infection. In the development of syphilis, genital lesions may occur, including urethral wall ulcers. This is caused by Treponema pallidum invading local tissues. However, not all urethral wall ulcers are caused by syphilis. Other infectious factors, such as urethritis, may be caused by bacteria, mycoplasma, chlamydia and other infections, but also lead to inflammation, ulcers and pain in the inner wall of the urethra. In addition, local damage, stimulation, or autoimmune diseases may also cause ulcers in the inner wall of the urethra. For example, improper catheterization operations, long-term use of irritant drugs, etc., may cause damage to the inner wall of the urethra, causing ulcers. Autoimmune diseases lead to abnormal immune response of the body, may also involve the urethral wall.
