A large proportion of patients in the nephrology clinic are found to have hematuria after routine urinalysis, and the next step is to exclude urinary stones, tumors, tuberculosis, infections, etc. by urinary ultrasonography, and one of the most important tests is urinary red blood cell bitemporal examination, which can broadly classify patients with hematuria into glomerular hematuria and non-glomerular hematuria, and if it is aberrant red blood cell urine, then the cause of that microscopic hematuria is glomerulogenic hematuria, at which time A nephrologist is needed to further exclude various causes of glomerular disease and finally determine it as primary glomerular disease hematuria (or occult glomerulonephritis). How do patients look at their hematuria 1.Visit regular nephrology department. 2.No blind medication should be used indiscriminately. 3.The necessary examination should be done. 4.The first six months when hematuria is found can be treated with some Chinese medicine appropriately. 5.Patients with more than six months can be treated without any drugs and follow up regularly at the outpatient clinic of nephrology. 6.There is no specific medicine for simple glomerular hematuria over 1 to 2 years, so those patients who like to take medicine are advised to be careful of the side effects brought by the medicine. 7.Some patients with such hematuria may last for life without any harm to the body. 8. Patients with other abnormalities such as proteinuria should have a kidney biopsy to clarify the diagnosis if necessary.
