Does a puncture biopsy hurt?

Puncture biopsy is a method of examining whether there are problems with various internal organs and what problems exist. It is widely used in clinical medicine. Many people think that puncture biopsy may be painful, but in fact, due to the improvement of medical level and puncture technology, there is generally no particularly strong pain during the puncture biopsy. The following is a detailed introduction to the relevant knowledge of puncture biopsy.

Overview of Needle Biopsy

In recent years, with the development of science and technology, the updating of imaging equipment and the improvement of operating skills, percutaneous renal biopsy technology has been widely used. It can directly observe the changes in renal morphology of kidney disease and conduct a series of observations. Due to the improvement of puncture technology, immunohistochemistry technology and electron microscopy, the quality of diagnosis has also been greatly improved. It has become an important means to diagnose kidney disease, guide treatment and predict prognosis. At the same time, it has also contributed to the causes and development trends of various glomerular diseases.

Is a needle biopsy painful?

As an invasive examination, renal puncture biopsy has a very "scary" name for some kidney disease patients. However, renal puncture biopsy is actually a local anesthesia, and there is almost no pain when the needle is inserted. During sampling, since there is no nerve supply to the renal parenchyma, the patient will not feel any pain. In addition, with the advanced equipment, with the help of color ultrasound guidance and fine needle puncture gun, the entire puncture process is fast and safe, with a success rate of 99%. After the anesthetic effect wears off, patients undergoing renal puncture surgery will not feel obvious pain at the puncture site. Some patients experience pain in their back and waist muscles due to lying flat for more than 8 hours after the puncture. Therefore, patients with kidney disease should not have too much psychological burden during the renal puncture biopsy. They should follow the doctor's instructions, undergo timely examinations and targeted and precise treatments, and strive for a speedy recovery.

Are there serious side effects of puncture biopsy?

Generally, renal puncture biopsy causes minor damage to renal tissue and is super minimally invasive. Clinicians will carry out necessary prevention and treatment before and after the operation to minimize the small probability of side effects. The operation will not affect the patient's kidney excretion of metabolic waste, regulation of body fluids, secretion of endocrine hormones and other physiological functions, nor will it affect the couple's sexual life and fertility. Common postoperative complications include microscopic hematuria (gross hematuria is also rare): the vast majority of patients have microscopic hematuria to varying degrees, and occasionally a few patients may have gross hematuria. Generally, no special treatment is required, and just prolonged bed rest can be sufficient. Secondly, some patients will have mild perinephric hematoma, but it is generally a small hematoma with no clinical symptoms and can be absorbed on its own within 1-2 weeks. Other complications include infection, arteriovenous fistula, massive bleeding, and accidental puncture of other organs, which are theoretically possible. However, the renal puncture biopsy technology is now very mature and is performed clinically by experienced attending physicians or above, and the probability of such complications occurring is very low.
