What causes high white blood cells in urine?
Disease description:

Elevated white blood cells in urine may include the following causes:
1. Urinary tract infection: Including cystitis, pyelonephritis, etc., bacterial infection is the most common cause. Women are more prone to urinary tract infections due to anatomical reasons.
2. Kidney disease: Such as glomerulonephritis, pyelonephritis, etc., these diseases cause kidney function damage, allowing white blood cells to enter the urine.
3. Urinary system stones: Stones moving within the urinary system may damage the urinary mucosa, causing an inflammatory response leading to increased white blood cells. In addition, stones can also cause urinary tract obstruction, increasing the risk of infection.
4. Prostate problems: Male patients may have increased white blood cells in urine due to prostatitis or benign prostatic hyperplasia.
5. Tumors: When tumors invade the urinary mucosa, they may also cause an inflammatory response leading to increased white blood cells.
6. Non-infectious inflammation: Certain non-infectious inflammatory conditions, such as interstitial nephritis, can also lead to elevated white blood cells in urine.
