What is the disease of sudden hematuria in men

There are many people suffering from urinary tract infections in life. Although urinary tract infections are more common among women, men occasionally suffer from urinary tract infections. The most obvious clinical manifestation of urinary tract infections is urethral pain when urinating and blood in the urine. Many men suddenly find blood in their urine when going to the toilet. What disease is this?

1. Kidney and urinary tract diseases

(1) Inflammatory diseases: acute and chronic glomerulonephritis, acute and chronic pyelonephritis, acute cystitis, urethritis, urinary tract tuberculosis, urinary tract fungal infection, etc.

(2) Stones in the renal pelvis, ureter, bladder, urethra, or anywhere else can rupture the urothelial tissue when the stones move, which can easily lead to hematuria and secondary infection. Large stones can cause urinary tract obstruction and even kidney damage.

(3) Tumors: Malignant tumors in any part of the urinary system or in adjacent organs that invade the urinary tract can cause hematuria.

(4) Trauma refers to violent injuries and injuries to the urinary system.

(5) Congenital polycystic kidney, congenital ultra-thin glomerular basement membrane, nephritis, nutcracker phenomenon (this disease is caused by congenital vascular malformation that causes compression of the left renal vein running between the abdominal aorta and the superior mesenteric artery, causing persistent submicroscopic hematuria. The right renal vein flows directly into the inferior vena cava, while the left renal vein must pass through the abdomen. The angle formed by the aorta and the superior mesenteric artery is injected into the inferior vena cava. Normally, this angle is 45° to 60°. If this angle is congenitally too small or filled with mesenteric fat, enlarged lymph nodes, or peritoneum, it can cause the nutcracker phenomenon. Diagnosis mainly relies on CT, B-ultrasound, and renal venography. Treatment requires surgical correction).

2. Systemic diseases

(1) Bleeding diseases: thrombocytopenic purpura, allergic purpura, hemophilia, leukemia, malignant histiocytosis, aplastic anemia, etc.

(2) Connective tissue diseases: systemic lupus erythematosus, dermatomyositis, polyarteritis nodosa, scleroderma, etc.

(3) Infectious diseases: leptospirosis, hemorrhagic fever, filariasis, infectious bacterial endocarditis, scarlet fever, etc.

(4) Cardiovascular diseases: congestive heart failure, renal embolism, and renal venous thrombosis.

(5) Endocrine metabolic diseases: gouty kidney, diabetic nephropathy, and hyperparathyroidism.

(6) Physical and chemical factors such as food allergies, radiation exposure, drugs (such as sulfonamide, phenol, mercury, lead, arsenic poisoning, large-scale infusion of mannitol, glycerol, etc.), poisons, and post-exercise.
