What is the reason for sudden lack of urine

The condition of urine can reflect a person's physical condition. Some people drink a lot of water during the day, but rarely go to the toilet. If the urine is little, toxins in the body cannot be excreted in time. There are many reasons for less urine. First of all, you should consider whether there is a kidney-related disease. For the sake of your health, it is best to go to the hospital for a check-up and diagnosis.

Causes of oliguria:

1. Prerenal oliguria:

(1) Insufficient blood volume: It starts with functional oliguria and anuria. Once the blood volume is replenished, the urine volume will recover immediately. If it is not diagnosed and treated in time, it may cause organic kidney damage. Acute renal failure, manifested by oliguria or anuria, is seen in severe dehydration, massive bleeding, extensive burns, etc.

(2) Shock: Shock due to various reasons causes a decrease in renal perfusion pressure and a serious deficiency in glomerular filtration rate, which is seen in anaphylactic shock, hemorrhagic shock, cardiogenic shock, infectious and toxic shock, etc.

(3) Decreased cardiac output: At this time, the blood supply to the kidneys decreases significantly, which is seen in left heart failure, severe arrhythmias, cardiac tamponade and constrictive pericarditis.

2. Renal oliguria and anuria:

(1) Renal parenchymal damage: Whether it is primary glomerulonephritis or secondary to systemic lupus erythematosus, polyarteritis nodosa, infective endocarditis, dermatomyositis, etc., it can cause renal parenchymal damage and even renal function damage or failure, resulting in oliguria and anuria. In the late stage of chronic renal failure, the kidneys atrophy, the glomerular filtration rate decreases, and the urine volume may be significantly reduced or even anuria; in the oliguria and anuria stage of acute renal failure, the symptoms are oliguria and anuria.

(2) Renal interstitial disease: The most common drug allergies such as penicillin, sulfonamides, rifampicin, aminoglycosides, etc. cause renal interstitial damage. It is also seen in the late stage of renal damage in chronic pyelonephritis. Acute pyelonephritis is seen in renal papillary necrosis. Heavy metal salt poisoning is seen in poisoning by mercury, lead, arsenic, gold, etc.

(3) Renal vascular diseases: renal cortical vasospasm or embolism, reduced renal blood supply leading to oliguria or anuria, seen in disseminated intravascular coagulation (DIC), pregnancy-induced hypertension syndrome, large-area burns, etc.

3. Postrenal oliguria and anuria are common in urinary tract obstructions such as stones, tumors, prostatic hypertrophy or prostate cancer, diabetic neurogenic bladder, etc. Treatment: Medical research shows that oliguria is directly related to the presence of kidney disease. Therefore, the prerequisite for treating oliguria is to treat kidney disease.

For the treatment of kidney disease, the hospital uses the "bidirectional immune renal restoration treatment system." It is reported that this therapy is a revolutionary treatment for kidney disease in the 21st century. It is a landmark event for China to show the world its achievements in treating kidney disease. It has received much attention and praise from the medical community. According to authoritative nephrologists, the main cause of oliguria is kidney disease. Therefore, if you want to reduce the current situation of oliguria, you need to treat your kidney disease. It is reported that the hospital's "bidirectional immune renal restoration treatment system" has a very good effect in the treatment of kidney diseases.
