Are infections the primary cause of pus in the urethra?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Pus in the urethra, known as urethral discharge, is most often caused by infections such as sexually transmitted infections (STIs) like gonorrhea or chlamydia, or by urinary tract infections (UTIs). This symptom typically signals inflammation of the urethra (urethritis) and should not be ignored, as untreated infections can lead to complications.

Because urethral pus can stem from several different conditions, identifying the underlying cause is essential for proper treatment. A fast, private, and free online symptom check can help you clarify what may be causing your symptoms and guide your next steps—whether that means seeing a doctor, getting tested, or simply gaining peace of mind. Taking a few minutes now could save you time, worry, and potential complications later.
