Unclassified urine crystals of more than 100 (units/uL) are more serious. End-classified urine crystals refer to smaller inorganic salt crystals in urine, which can also be understood as tiny stones or stone precursors. The normal range of urine unclassified crystals is generally in the range of 0-28 (units/uL). If the urine end-classified crystals reach more than 100 (units/uL), it is already far beyond the normal range and is a more serious case. Unclassified urine crystals of more than 100 (units/uL) may be a result of pathological factors, such as the presence of inflammatory diseases of the urinary system, common diseases include inflammation of the bladder, glomerulonephritis, and pyelonephritis. These diseases can cause an increase in inflammatory deposits in the urine, which in turn can cause an increase in unclassified crystals in the urine. Some patients may also experience some degree of urgency or painful urination, which in more severe cases may cause discomfort such as incomplete urination. It is necessary to use anti-inflammatory drugs under the guidance of a doctor, such as oral levofloxacin hydrochloride capsules, or cefixime dispersible tablets, etc. If the urine has more than 100 unclassified crystals (units/uL) and the subject does not have urinary tract inflammation, it indicates that there are more crystals in the urine, which can easily form kidney stones or bladder stones. The formation of stones can lead to painful symptoms in the abdomen and interfere with the patient’s normal urination, such as painful urination or blood in the urine, which affects normal metabolism. Patients with small stones can be treated with oral medications such as potassium citrate pellets and lithotripsy pellets under the guidance of a doctor. If the stones are large, laser lithotripsy can be performed.
