Pus in the urine

Pus in the urine is a symptom of a urinary tract infection, and is characterized by cloudy or foul-smelling urine. It often develops gradually, with the presence of pain or burning upon urination, increased frequency, and urgency. In more severe cases, fever, chills, and nausea may also be present. The pus may appear as white, yellow, or green in color, and may contain bacteria, white blood cells, and other debris. Treatment usually involves antibiotics, and may include fluid and electrolyte replacement.
