Causes of Painful Urination and Blood in Urine
Recently, I have been experiencing significant pain and blood in my urine when urinating. Doctor, I would like to ask what are the causes of painful urination and blood in the urine?

Causes of painful urination and blood in urine include:
1. Urinary tract infections: Including cystitis, pyelonephritis, etc., caused by bacterial infections. Common symptoms include frequent urination, urgency, painful urination, and blood in the urine.
2. Stones: Urinary tract stones can cause severe pain accompanied by blood in the urine. When stones move or obstruct the urinary tract, they may irritate the urethra or damage the urinary mucosa, causing bleeding.
3. Prostate diseases: In male patients, prostatitis or benign prostatic hyperplasia can cause painful urination and hematuria, especially noticeable at the end of urination.
4. Kidney diseases: Such as glomerulonephritis, renal vascular diseases, etc., which may affect kidney function and lead to hematuria.
5. Trauma: Physical injury to the urethra, bladder, or kidneys can also cause blood in the urine and painful urination.
6. Genetic disorders: Such as thin basement membrane disease, which can cause persistent hematuria.
7. Vascular abnormalities: Vascular malformations or hemangiomas may sometimes lead to hematuria.
If symptoms persist or worsen, prompt medical attention is recommended.
