Second, urinary tract stones, when the size of the stone is relatively large, stuck in the ureter or urethra, the stone is easy to cut through the tube wall, resulting in bleeding, which will lead to positive urine occult blood.

Third, kidney lesions, common IgA nephropathy, glomerulonephritis, due to renal lesions lead to a decrease in the filtration function of the kidneys, red blood cells in the blood leak into the urine through the kidneys, resulting in positive urine occult blood.

If ** is more common in glomeruli in nephritis, otherwise it can be seen in urinary tract infection, tuberculosis, tumors, stones, trauma, pollution, etc., and it is necessary to combine clinical symptoms, and if necessary, further examination.

Increased red blood cells in the urine.

Whether it's glomerulonephritis, pyelonephritis or cystitis, it can cause potential bleeding in the urine; Stone.
