If the urine is yellow and cloudy, it is recommended to go to the hospital for further examination and treat the symptoms according to the specific causes. 1. If the examination confirms the presence of urinary tract infection, it is recommended to give anti-infection treatment, which can be oral levofloxacin hydrochloride capsules or ciprofloxacin tablets, or intravenous infusion of levofloxacin hydrochloride injection. The treatment course is one week, and after a week, the urine will be rechecked again to clarify whether the infection is completely cured. 2. If there is a concentrated state of urine, it can be manifested as yellowish and cloudy urine, and this situation requires proper hydration, such as oral rehydration. For patients with diarrhea, vomiting, and dehydration, it is recommended that intravenous fluids be given, which can be supplemented with about 1,000 ml of saline or glucose, and then observe whether the color of the urine is cloudy and yellow, etc. 3. If there is an increase in urine precipitation, such as an increase in urine salt crystals, or the presence of stones in the urine, it is recommended that more water be consumed appropriately. Drink more than 2000ml of water per day, and further review of the ultrasound of the urinary system is needed. The presence of precipitation in the bladder or the presence of crystals in the kidneys, ureteral crystals and stones, etc. requires the administration of extracorporeal shock wave lithotripsy or the administration of drugs to inhibit crystallization, such as oral sodium potassium hydrogen citrate granules, 10g/time, 1 time/day, for 10 consecutive days orally before regular rechecking.
