Hematuria and urinary protein are two concepts, but most of the diseases that produce hematuria will cause urinary protein, and the causes of hematuria are pyelonephritis, IgA nephropathy, renal tumors and so on, and the above diseases can be accompanied by urinary protein to a greater or lesser extent as follows: 1, pyelonephritis and renal tumors, patients with pyelonephritis and renal tumors can have reddish urine, and the urine routine checking will show that there are a large number of red blood cells in the urine, and the urine protein is positive or weakly positive. Positive or weakly positive, the cause of urine protein is inflammation or tumor stimulation. 2, IgA nephropathy, IgA nephropathy patients with blood in urine, but urine routine can see urine protein is positive, the cause of urine protein is IgA-based immune complexes deposited to the kidneys, caused by glomerular inflammation, glomerular damage to the glomerular filtration barrier is impaired, the leakage of urinary protein, so the protein positive. Protein positivity occurs.
