Chronic kidney disease in patients with renal insufficiency in daily urine volume change pay great attention to their own, found that the urine volume decreased suddenly. The thought is very tense, and think that you are to the renal failure stage. Some doctors don't anuria cause analysis of patients with urine volume decreased, the indiscriminate use of diuretics like furosemide, this is invalid on the other hand, to reduce renal failure. Therefore, attention should be paid to the analysis of the causes of chronic renal insufficiency in patients with urine output, and take corresponding measures is very important.

In patients with chronic renal failure, the reduction of urine volume should be considered in 3 aspects: pre renal factors, renal factors and post renal factors

(1) pre renal factors, mainly blood volume insufficiency;

The causes of long-term loss of appetite, intake insufficient, nausea and vomiting and diarrhea loss of extracellular fluid, long-term salt restriction and excessive diuresis. Due to insufficient blood volume, reduced renal blood flow and perfusion defects, so that the urine volume decreased. Treatment should supplement blood volume increase the urine volume, blood loss and avoid using diuretic capacity. Exacerbation of renal failure. The diagnosis of hypovolemia mainly from patients with tachycardia, orthostatic hypotension, tongue dry, the skin loses its elasticity, combined with the history of that.

(2) renal factors, mainly progressive lesions of the renal parenchyma

The renal insufficiency gradually develop kidney failure, and urine volume decreased gradually, even when anuresis serum creatinine, blood urea nitrogen increased, hemoglobin decreased gradually, the general condition is getting worse, poor prognosis, even if the application of diuretics also to no avail.

(3) post renal factors are mainly urinary tract obstruction or infection

Because of the formation of urination urine retention, early can have frequent micturition, urgency, dysuria and other urinary bladder irritation symptoms; late loss, abdominal pain unbearable, lung swelling trigone of bladder. The urinary retention should take effective anti infection in the first place, at the same time, it is necessary to find out the cause of obstruction, relieve the obstruction to urinary tract smooth. Urinary tract obstruction is exacerbated the deterioration of renal function, but is reversible, and make timely diagnosis and take positive measures is very important.
