Hematuria and occult blood under the microscope of physical examination, just like my wife, what's the matter?

Possible causes of occult blood in urine are:

1, IgA nephropathy: It can be characterized by continuous microscopic hematuria without other symptoms, and it is a relatively benign nephropathy. Renal biopsy can be confirmed, but asymptomatic, proteinuria, abnormal renal function and hypertension are not recommended, so close observation and regular examination can be carried out.

2, urinary calculi: often paroxysmal low back pain, side abdominal pain, may be accompanied by frequent urination, dysuria and other bladder irritation symptoms.

3. Renal tuberculosis and renal tumor: painless gross hematuria is the main symptom, and renal tuberculosis is often accompanied by bladder irritation symptoms such as low fever, night sweats, anemia and tuberculosis poisoning symptoms; Hematuria caused by renal tumor is mostly severe hematuria, and the onset age is mostly over 40 years old.

4. Nephropathy or kidney swimming: The main symptoms are abdominal mass, pain in the renal area after fatigue or standing for a long time. Diagnosis can be made by pyelography (compared with standing position).

5, congenital renal abnormalities: congenital polycystic kidney, solitary kidney and so on. It can be manifested as simple hematuria. B-ultrasound and CT are helpful for diagnosis.

6. Hematological diseases: Some hematological diseases can cause hematuria due to thrombocytopenia, increased capillary permeability and disorder of coagulation mechanism, such as thrombocytopenic purpura, hemophilia and malignant reticular cell disease.

7. Exercise-induced hematuria: Healthy people can also have hematuria after strenuous exercise.

8. Other rare reasons: Some immune, metabolic and genetic diseases have corresponding other manifestations.

9, urinary tract adjacent organ diseases: female pelvic inflammatory disease can have hematuria, colon and ovarian tumors can also cause hematuria.

10, Pollution: Women's unclean menstruation can pollute urine samples and cause "hematuria".

1 1. Idiopathic hematuria: no urogenital diseases, no abnormalities in all tests, and normal renal biopsy. The reasons may be: small renal hemangioma or vasodilation, renal calyceal-venous pathway, small stones, increased renal vascular permeability and bleeding.
