The presence of precipitate in urine is not a normal phenomenon. Normal urine should be clear and transparent without any precipitating properties, and if precipitation occurs, you need to go to the hospital for urine-related examination to clarify the cause of the precipitation. If urinary tract infection occurs, white flocculent or feathery precipitate may appear in the urine, along with cloudy urine, accompanied by symptoms such as frequent urination, urgent urination and painful urination, and an increase in the number of white blood cells bacteria in the urine can be seen in routine urinalysis tests. If salt urine or crystalluria occurs, there can also be an increase in precipitates, both due to concentrated urine or increased content of components in the urine, and supersaturated precipitation to form crystalline like precipitates, such as oxalate and phosphate, can lead to the formation of crystals. Excessive uric acid can also form precipitates associated with uric acid crystals, which require routine urinalysis to further confirm the diagnosis. Patients who have had urinary stones can also have precipitates with stones in their urine if they have undergone treatment such as extracorporeal shock wave lithotripsy or medication for stone removal, mostly fine stones are discharged.
