Urine Infection
Normally, urine should be clear in appearance and without odor. Cloudy urine could be a strong sign of a disease in either or both of the kidneys, probably a kidney stone. Pus due to an infection in the urinary tract may be discharging substances into the urine. What’s more, infection of the urinary tract may be a sign of a kidney stone. Symptoms of infection usually mimic those of kidney stones, including high body temperature, chills, fatigue or tiredness, cloudy or foul-smelling urine, and diarrhea. These might be due to the accumulation of waste in the obstructed urine, perhaps causing the invasion of bacteria.
