Which STDs are associated with pus in urine?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Pus in urine (pyuria) can be a sign of a sexually transmitted disease (STD). Common STDs linked to pyuria include chlamydia, gonorrhea, and trichomoniasis. These infections often cause inflammation in the urinary tract or genitals, leading to white blood cells (pus) appearing in urine. Other symptoms may include painful urination, discharge, or pelvic pain.

Because pus in urine can also point to non-STD causes like urinary tract infections or kidney issues, identifying the root cause is essential for proper treatment. Left untreated, STDs can lead to serious complications, including infertility. The fastest way to understand your symptoms and know what to do next is to take a free, instant, online symptom check—it's private, doctor-developed, and can help you decide whether to see a provider today.
