What Are the Symptoms Of Kidney Disease?

Renal failure is a manifestation of the gradual decline of kidney function after damage. If it is not controlled and treated in time, kidney failure will quickly develop into uremia, and the kidneys will gradually lose their function and become a burden on the body. In the early stages of renal failure, there are usually no symptoms to warn patients that their kidneys are not working properly. When kidney function is almost completely lost, the patient's physical changes and symptoms become apparent. Patients with kidney failure will have different symptoms.

Kidney failure symptoms

The symptoms of renal failure are as follows:

Several chronic kidney diseases cause scar formation in kidney tissue, cause intrarenal obstruction, and cause poor local urine flow;

renal dysfunction, decreased urine flow, prolonged storage of urine in the bladder, and is conducive to the reproduction of bacteria;

Patients with chronic renal failure have decreased immunity and resistance, weakened leukocyte migration and phagocytosis, and patients with uremia have reduced appetite, malnutrition, anemia, and metabolic acidosis, which will further weaken their resistance and be vulnerable to urinary tract infections. .

Chronic renal failure

In general, the tests that patients with renal failure need to do are routine blood tests, routine urine tests, renal function tests, blood biochemical tests, etc., mainly including the following:

1. Routine blood test for renal failure: Patients with renal failure usually have obvious anemia in the routine blood test, which is normal cellular anemia, and the number of white blood cells is normal or increased, platelets are reduced, and the rate of fine cell sedimentation is accelerated.

2. Routine urine examination for renal failure: In patients with renal failure, routine urine examination will generally show the following characteristics:

The urine osmotic pressure is lower than 450mOsm per kg, and the weight is lower than 1.018. In severe cases, it is fixed between 1.010 and 1.012. When urine concentration and dilution test is performed, nocturnal urine volume is greater than daily urine volume, and each time urine specific gravity Both exceeded 1.020, and the difference between the highest and lowest urine specific gravity was less than 0.008;

decreased urine output, mostly below 1000ml per day;

Quantitative increase of urinary protein, due to the majority of the glomerulus has been destroyed in the later period, but urinary protein has decreased;

urine sediment examination, how many different types of red blood cells, white blood cells, epithelial cells and granular casts, waxy casts are the most significant.

3. Renal function test for renal failure: In terms of renal function test, patients with renal failure show that all indicators are diminished.

4. Blood biochemical examination of renal failure: Patients with renal failure will experience symptoms such as decreased albumin in plasma, low blood calcium, increased blood phosphorus, and low blood potassium during this test.

In addition, in addition to the main examinations mentioned above, patients with renal failure need to perform X-ray urography and radiography, isotope nephrogram, kidney scan, renal biopsy, etc. Help a lot.
