Among patients with common kidney disease, a large proportion of patients have simple microscopic hematuria or carnal hematuria. The routine examination and diagnostic measures for such patients can be carried out as follows for your study and reference: For hematuria, firstly, we can understand the morphology of red blood cells in urine by “urine red blood cell morphology analysis” and “urine three-cup test”, and then we can initially determine the nature and origin of hematuria based on morphology. The nature and origin of the hematuria can be determined based on the morphology. If the hematuria is mainly “deformed red blood cells” and “glomerulonephritis” is considered, the diagnosis can be clarified by “kidney aspiration biopsy” and further treatment plan can be guided if there are no contraindications. In such patients, it is necessary to check the pharynx and tonsils for inflammatory changes, as chronic tonsillitis can often cause “glomerulonephritis”. If the patient is predominantly normal red blood cells, the patient should be examined by ultrasound, CT or magnetic resonance imaging of the urinary system and, if necessary, by endoscopy such as cystoscopy and ureteroscopy, which can provide a more visual and clear understanding of the renal pelvis, ureter, bladder mucosa and prostate. If necessary, biopsies can be taken for pathological examination to help make a clear diagnosis. I hope the above reply can help you, go to the urology department or nephrology department of a large hospital as soon as possible, and wish you a speedy recovery.
