First of all, let’s understand what hematuria is? Generally, urine containing a certain amount of red blood cells is called hematuria. The amount of blood in 1000ml of urine contains more than 1ml and the urine has a red appearance called hematuria . There is no abnormal appearance of urine. The fresh urine centrifugal sediment checks more than 3 red blood cells per high-power field, which is called microscopic hematuria.
Whether hematuria can be cured has a great relationship with the primary disease. Hematuria caused by acute urinary tract infection is easy to cure .
Hematuria caused by acute glomerulonephritis . Most patients will return to normal after rest treatment, and hematuria will also be spontaneously relieved.
Hematuria caused by acute nephritis Although hematuria itself may gradually reduce, some patients will quickly progress to end-stage renal failure.
Hematuria caused by chronic glomerular disease will also recur due to the recurrence of the disease, which is also one of the manifestations of recurrence of the disease.
Hematuria caused by urinary tract tumors can also be relieved or stopped by itself, often giving people the illusion of self-healing. Hematuria will also occur again when the disease recurs.
What diseases may hematuria be related to?
Acute glomerulonephritis
This disease is mainly caused by the immune response induced by β-hemolytic streptococci infection, mainly manifested in hematuria, proteinuria, edema and hypertension , which may be accompanied by transient renal insufficiency.
Chronic glomerulonephritis
is based on hematuria, proteinuria, edema and hypertension. The onset methods are different, and the condition is prolonged and progresses slowly.
IgA nephropathy
is characterized by glomerular disease mainly deposited by IgA or IgA in the mesangial region of the glomerular region, which is often manifested as asymptomatic hematuria with or without proteinuria.
lupus nephritis
lupus nephritis is systemic lupus erythematosus kidney damage. Its mechanism is mainly caused by the deposition of the circulating immune complex in the glomerulus causing inflammatory responses to cause kidney damage, which can manifest as asymptomatic hematuria and (or) proteinuria.
Vascularitis-related nephritis
is mediated by ANCA and mainly involves small blood vessels throughout the body. Necrotizing vasculitis and crescent can occur in the kidneys. Immunofluorescence is oligoimmune deposition, and there may be asymptomatic hematuria throughout the whole process or microscopic hematuria. Renal function progresses rapidly and may have extrarenal symptoms.
Urinary system infection
Acute pyelonephritis patients are usually caused by Gram-negative bacillus, among which Escherichia coli is the most common, accompanied by chills, high fever, hematuria and other symptoms. Patients with acute bacterial cystitis will have symptoms such as urination pain, frequent urination , and urgency, and terminal hematuria is common.
Urinary tract stones
Urinary tract stones are formed in the kidneys and bladder, which can cause direct urinary tract damage to the urinary tract and lead to hematuria. Usually, it is microscopic hematuria, and a few patients can see naked eye hematuria.
Urinary system tumor
Renal tumor is one of the common tumors in the urinary system, and intermittent painless hematuria is a common symptom. Bladder tumor About 85% of patients have intermittent painless whole-course hematuria, which can be relieved or stopped by themselves, which can easily cause the patient to feel better and delay treatment.
Urinary system trauma
Most patients with urinary system trauma have hematuria. When renal contusion involves the renal collection system, microscopic hematuria or mild hematuria may occur.
polycystic kidney
polycystic kidney is mainly autosomal dominant, and its pathological characteristics are that both kidneys form cysts widely and develop sexually, ultimately destroying the structure and function of the kidneys. This disease is prone to complications of stones and infections, and hematuria is often caused by this complication.
Hemorrhagic diseases
Thrombotic thrombocytopenic purpura is often accompanied by kidney damage, accompanied by hematuria and proteinuria.
In short, don’t panic when you have hematuria, just go to the hospital for further examination immediately. Eliminate the cause and hematuria will naturally disappear. Follow me to learn more about medical knowledge!
