Renal puncture is a test to diagnose kidney disease. Although it is an invasive test, this test was carried out earlier and the technology is relatively mature, which causes less damage to the body and usually does not affect life expectancy. What really has an impact on life expectancy is kidney disease. Through kidney puncture, the pathological type of the disease can be clarified to guide the treatment and prognosis. As for how many years one can live, there are large differences, which are related to the patient’s age, the severity of the disease, the presence of complications, and the pathology of kidney damage. Some patients with mild kidney disease can basically be cured with regular drug treatment and will not affect their life expectancy. While some patients have more serious kidney disease, which may progress to uremia within a few years and may affect the patient’s life and quality of life. After kidney puncture, you must lie flat in bed for 6 hours, and after 6 hours, you can do slight lateral activities. After 24 hours, if there is no blood in urine or hematoma around the kidney, you can go down to the floor.
