The percentage of normal red blood cells in the urine routine is 100%, which is homogeneous red blood cells, usually suggesting non-glomerular origin hematuria, which is mostly seen in diseases such as urinary stones, urinary tract infections, and urinary tract tumors.
1. Urinary stones: such as renal stones, ureteral stones, etc., stones may damage the urinary tract epithelium, mucosa, hematuria may occur, this red blood cells generally do not pass through the glomerular basement membrane, the morphology of red blood cells and peripheral blood red blood cells do not have significant differences in morphology.
2. Urinary tract infections: such as cystitis, urethritis, etc., the inflammation repeatedly stimulate the urethral epithelium, the blood vessels of the bladder mucosa, mixed in the urine, the symptom of hematuria, the morphology of erythrocytes in such cases is generally uniform and does not change.
3. Urological tumors: such as bladder cancer, if the tumor cells invade the peripheral blood vessels, there may be hematuria or microscopic hematuria, but the morphology of erythrocytes usually does not change.
There may be other reasons for 100% of normal red blood cells in urine routine. It is recommended that patients go to regular hospitals in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
