What is the cause of bleeding in men's urine?

Hematuria is often caused by diseases of the urinary organs. Human urine is produced in the kidneys and excreted from the body through the renal pelvis, ureters, bladder, and urethra. If any of these organs are diseased or bleeding occurs, it can cause hematuria. Common diseases that cause hematuria include various nephritis, urinary tract infection, hemorrhagic cystitis, urinary tract stones, renal tuberculosis, renal tumors, kidney and urethra injuries, etc. Hematuria is one of the main symptoms of the above diseases. 1. When urination starts with hematuria and then becomes normal, it is usually caused by urinary tract infection or urethral disease. 2. If urination starts normally but hematuria appears near the end, it is usually caused by cystitis and prostate disease. 3. If hematuria occurs throughout the whole process and the blood is dark red, it is usually caused by kidney disease. More than 95% of hematuria in men is caused by diseases of the urinary system itself, among which glomerular diseases (acute nephritis, rapidly progressive nephritis, membranoproliferative nephritis, mesangial proliferative nephritis, focal glomerulosclerosis, etc.), renal cysts, stones (kidney, ureter, bladder, urethral stones), prostate hyperplasia, urinary tract infections (tuberculosis, pyelonephritis, cystourethritis, prostatitis) and tumors (kidney, ureter, bladder, prostate tumors) are the most common.

1. Kidney diseases: pyelonephritis, hematuria with dysuria, urgency, frequency, low back pain, and fever. 2. Acute glomerulonephritis with hematuria, oliguria, proteinuria, edema, hypertension, and tonsillitis one week before the onset of the disease. 3. The characteristics of urinary system stones are hematuria accompanied by renal colic, or symptoms such as interrupted urination, difficulty urinating, and painful urination. 4. More than 90% of patients with renal tuberculosis have hematuria, which is characterized by gradually increasing urgency, frequency and pain when urinating. 5. Kidney and urinary tract injuries are often accompanied by a history of lumbar or abdominal trauma, such as bruises, collisions, falls, etc.
