1 renal and urinary tract diseases
(1): acute and chronic inflammation, glomerulonephritis, acute and chronic pyelonephritis, acute cystitis, urethritis, urinary system tuberculosis, urinary tract fungal infection.
(2), stone: renal pelvis, ureter, bladder, urethra, any part of the stone, when the stones move through the urinary tract epithelial, that is easy to cause hematuria is also easy to secondary infection. Large stones can cause urinary tract obstruction and even cause renal damage.
(3) tumors: malignant tumors of any part of the urinary system or malignant tumor of adjacent organs and urinary tract invasion can cause hematuria.
(4), trauma: refers to violence and urinary system.
(5), drug stimulation: such as sulfanilamide, phenol, mercury, lead, arsenic poisoning, a large infusion of mannitol, glycerol, etc..
(6) congenital malformations: polycystic kidney disease, congenital glomerular basement membrane. Nutcracker phenomenon, the disease is caused by congenital malformations of the blood vessels in the abdominal aorta and superior mesenteric artery between the left renal vein squeezed, causing stubborn microscopic hematuria called Nutcracker phenomenon. Straight into the right renal vein and inferior vena cava, the left renal vein must wear angle of abdominal aorta and superior mesenteric artery formed by implantation of inferior vena cava. Normal angle of 45 degrees ~60 degrees, if the congenital angle is too small or mesenteric fat, swollen lymph nodes, peritoneal filling can cause the Nutcracker phenomenon. The diagnosis mainly depends on CT, B ultrasound and renal venography. Treatment must be corrected.
2 systemic diseases
(1), hemorrhagic disease: thrombocytopenic purpura, Henoch purpura, hemophilia, leukemia, malignant histiocytosis, aplastic anemia.
(2), connective tissue disease, systemic lupus erythematosus, dermatomyositis, scleroderma, polyarteritis nodosa, etc..
(3), infectious disease, leptospirosis, epidemic hemorrhagic fever, filariasis, infectious bacterial endocarditis, scarlet fever, etc..
(4) cardiovascular disease: congestive heart failure, renal embolism, renal vein thrombosis.
(5) endocrine and metabolic diseases: Gout kidney disease, diabetic nephropathy, hyperparathyroidism, 3 adjacent organ diseases: tumor invasion of the uterus, vagina or rectum.
