Can trichomoniasis cause a UTI?

Trichomoniasis affects the genital area and can irritate the opening of the urethra, making urination sting. A UTI usually involves bacteria in the urinary tract. Because the sensations overlap, burning alone cannot identify the cause. Trichomoniasis may also bring unusual discharge, genital itching, or pain during sex; these features can point clinicians toward a genital infection rather than a bladder infection.

A [Vaginal Discharge](/symptoms/vaginal-discharge/) page can help you describe changes, while [Vaginal Itching](/symptoms/vaginal-itching/) may be another relevant symptom. Testing, rather than symptom pattern alone, distinguishes the conditions.

Arrange an assessment if burning persists, follows sexual contact, or occurs with discharge or itching. A clinician may assess urine and genital samples because more than one infection can occur at the same time. Do not use leftover UTI antibiotics or take someone else’s medicine. If trichomoniasis is diagnosed, take the prescribed treatment and follow advice about partner care and avoiding sex during treatment. See information about [Antibiotic Treatment for Pelvic Infection](/treatments/medical-gynaecology/antibiotic-treatment-for-pelvic-infection/).

Seek prompt medical care for painful urination with fever, back or side pain, blood in urine, pelvic pain, or worsening symptoms. If you are pregnant, have a partner with trichomoniasis, or symptoms continue after treatment, contact your clinician promptly.

Ask whether your symptoms fit trichomoniasis, a UTI, or both; which samples are needed; and when you should expect follow-up if symptoms do not settle.
