Which urine test shows kidney disease

Routine urine tests can indeed help us understand and rule out some kidney problems to a certain extent, but we cannot diagnose the disease based solely on the results of routine urine tests. In addition to these examination methods, we must also combine the patient's clinical symptoms and other more confirmed treatment methods to clearly understand the disease and know how to treat it.

1. Urinalysis + B-ultrasound + puncture

The most annoying thing about kidney disease is that there are no symptoms in the early stages. However, once problems such as decreased appetite, anemia, headache, shortness of breath, and palpitations appear, these are signs of decreased kidney function or even a precursor to uremia.

2. How to detect kidney disease

Urinalysis, B-ultrasound, renal puncture and other examinations can promptly detect whether there are any problems with the kidneys and how the kidney function is. "Everyone must insist on having a routine urine test once a year." Many people mistakenly believe that routine blood tests are more reliable, and that elevated blood creatinine means kidney damage. However, in nephrology, routine urine tests are more relied upon because they detect changes in red blood cells and protein in the urine, which are the earliest signs of whether the kidneys are damaged. B-ultrasound is a means of detecting kidney stones and congenital polycystic kidney disease. Most people will feel pain when stones block the ureter, but some people do not feel any pain. Some people do not discover the disease until the stones block the ureter to the point of water accumulation and kidney function is damaged. Therefore, an abdominal B-ultrasound once a year can help detect kidney stones. B-ultrasound cannot reveal everything. It is best to combine it with a routine urine test and do it once a year.

3. How to read urine routine results

Shi Wei said that nowadays, when checking urine, the automatic biochemical analyzer provides dozens of data, and the presence or absence of urine protein, red blood cell count, white blood cell count, urine specific gravity, uric acid alkalinity, presence or absence of occult blood, etc. are the indicators that the nephrology department pays attention to. There are no clinical symptoms in the early stages and the body feels normal, but even if the glomeruli are not swollen, any small damage to the kidney will be reflected in the urine, that is, an increase in red blood cells and white blood cells; increases or decreases in urine specific gravity reflect changes in the kidney's concentrating function, and a urine osmotic test may be required after a few hours; urine is generally acidic, and if increases or decreases occur, it may be acidosis, causing the kidneys to fail to excrete acid.
