What is the reason for increased red blood cell count in urine endoscopy

An increase in red blood cells on uroscopy may be caused by urinary tract infections, stones, nephritis, tumors, or physiological factors, and other examinations should be combined to determine the cause.

1. Urinary system infection:

Infections such as cystitis or pyelonephritis can cause congestion and damage to the urinary tract mucosa. The toxins produced by bacteria can damage capillaries and allow red blood cells to infiltrate urine. Patients often have symptoms of frequent urination and urgency, and need to undergo urine culture for diagnosis. The treatment mainly involves antibiotics, while increasing water intake to flush the urinary tract.

2. Urinary tract stones:

Kidney or ureteral stones may scratch the epithelium of the urinary tract when they move. Friction between stones can cause mechanical damage, leading to local bleeding. The typical manifestation is sudden lumbar and abdominal colic accompanied by hematuria. The location of the stone can be determined through ultrasound or CT, and medication or extracorporeal lithotripsy treatment can be selected according to its size. 3. Glomerular diseases: Acute nephritis or IgA nephropathy can damage the glomerular filtration membrane. The deposition of immune complexes damages the filtration barrier, causing red blood cells to leak into the urine. Often accompanied by edema and hypertension, diagnosis requires renal biopsy. Treatment includes hormone control of immune response, combined with antihypertensive drug management.

4. Urological tumor:

bladder cancer or renal cancer tissue with abnormal growth, blood vessels are prone to rupture and bleed. Tumor erosion of blood vessels can lead to persistent painless hematuria, which is common in middle-aged and elderly smokers. Early detection through cystoscopy and imaging examination can result in surgical resection of the lesion.

5. Physiological factors:

Intense exercise or menstrual pollution may cause pseudoerythrocytosis. Changes in renal blood flow during exercise can cause red blood cells to leak out, and female menstrual blood mixed with urine samples can also interfere with the results. It is recommended to avoid menstrual follow-up and avoid high-intensity exercise 24 hours before the examination.

In case of abnormal red blood cells in urine, record the urination characteristics and observe whether there is foam urine or low back pain. Maintain a daily water intake of 2000 milliliters and limit a high salt and high protein diet. To avoid prolonged holding of urine and excessive fatigue, it is recommended to have a urine routine check every six months. People over 40 years old who experience painless hematuria should be promptly screened for possible tumors, and if necessary, undergo a specialized examination of the urinary system.
