Trichomoniasis: This sexually transmitted infection is known for causing green or yellowish vaginal discharge, often accompanied by other symptoms such as itching, burning, and irritation. The presence of UTI symptoms could be due to the infection spreading or a concurrent infection.

Bacterial Vaginosis (BV): Although BV typically presents with a fishy odor and thin, white or gray discharge, some cases can have a greenish tint. UTI symptoms could be present if there's a concurrent urinary tract infection.
Chlamydia or Gonorrhea: These sexually transmitted infections can cause abnormal vaginal discharge and UTI symptoms, especially if the infection has spread to the urinary tract.
Vaginal Candidiasis: While typically associated with a thick, white discharge, some cases of vaginal yeast infections can present with a greenish discharge, especially if there's a mixed infection. UTI symptoms could be concurrent.

Pelvic Inflammatory Disease (PID): A serious condition that requires prompt treatment, PID can cause a range of symptoms including abnormal vaginal discharge, pelvic pain, and UTI symptoms. It's crucial to consider PID, especially in sexually active women, due to its potential for long-term complications.
Septic Abortion or Miscarriage: In pregnant women, green vaginal discharge accompanied by UTI symptoms could be indicative of an infected abortion or miscarriage, which is a medical emergency.

Foreign Body in the Vagina: A retained foreign object in the vagina can cause a foul-smelling, greenish discharge and potentially lead to UTI symptoms if the object irritates the urinary tract.
Cervical Cancer: Although extremely rare as a primary presentation, advanced cervical cancer can cause abnormal vaginal discharge, including green discharge, along with a range of other symptoms including pelvic pain and UTI symptoms.
