If there is 1 ml of blood in 1000 ml of urine, the naked eye looks like urine is blood sample or meat washing water sample, this is called naked eye hematuria. In routine urine examination, if there are more than 5 red blood cells in a high-power field under the microscope, or the red blood cell count of 12 hour urine Addy exceeds 1 million, and it cannot be detected by naked eyes, it is called microscopic hematuria. Common in a variety of nephritis, urinary tract infection, hemorrhagic cystitis, urinary calculi, renal tuberculosis, renal tumor, kidney and urethral injury, etc. Urinary calculi can directly damage the kidney, urethra and other tissues, causing bleeding, but also due to co infection and tissue cell damage, causing bleeding.

matters needing attention

However, parents do not have to worry too much. If the child has too little water intake or too much water loss, or has the phenomenon of crying when urinating, it may not be urinary stones. Parents should observe carefully when they see different crying or urine loss when their children urinate. If hematuria is found, they should suspect the possibility of kidney stones, because hematuria and pain are often the first symptoms of kidney stones. Hematuria can disappear by itself or appear repeatedly; If a child is found to have temporary anuria, it mainly reflects the presence of stones in the upper urinary tract (including kidney stones and ureteral stones) and has formed obstruction. Once the obstruction is relieved, urine is discharged; If the child is crying or struggling when urinating, it is suggested that the lower urinary tract stones (bladder stones, urethral stones) may occur.
