The dangers of kidney biopsy

Renal biopsy is also a common examination method, which has a good examination effect on kidney disease. This biopsy will cause some side effects in a small number of patients, such as low back pain, urinary retention, and even infection. At this time, you must pay attention to conditioning and use medication under the guidance of a doctor. If the situation is more serious, you should go to the hospital for examination in time.

Risks of having a kidney biopsy

Patients with very small local renal puncture may show low back pain, abdominal distension, urinary retention, infection, transient hypotension, hematuria, small hematoma, infection, and heavy bleeding after the operation.

Low back pain: The incidence rate is about 17-60%, and most cases disappear within a week.

Damage to other organs: This is often caused by improper puncture point or too deep needle insertion, which may damage organs. Severe cases may require surgical treatment.

Infection: The incidence of infection is low, mostly due to lax aseptic measures, existing perinephric infection or pyelonephritis. If fever, severe back pain, and increased white blood cell count are present, antibiotics are required for treatment.

Dynamic venous fistula: The incidence rate is 15-19%, and a small number of patients have no symptoms. Typical manifestations are severe hematuria and/or perinephric hematoma, refractory hypertension, progressive heart failure, and vascular murmurs in the waist and abdomen. Renal angiography is required for diagnosis. Most cases heal on their own within 3-30 months, and those with severe cases need timely surgery.

Significance of renal biopsy

Understanding the changes in renal tissue morphology provides an important basis for clinicians to judge the condition, treat the disease and estimate the prognosis. It can be said that the development of renal pathology examination is a leap forward in the development of nephrology. At present, the results of renal pathology examination have become the gold standard for the diagnosis of kidney disease. In summary, the clinical significance of renal puncture examination mainly includes the following points:

⑴ Clear diagnosis: Renal puncture biopsy can correct the clinical diagnosis of more than one-third of patients.

⑵Guiding treatment: Renal puncture biopsy can modify the clinical treatment plan of nearly one-third of patients.

⑶ Estimate prognosis: Renal puncture biopsy can more accurately evaluate the prognosis of patients with kidney disease.

In addition, sometimes repeated renal pathology examinations are needed to understand the effectiveness of treatment or the progression of pathology (such as crescentic nephritis, lupus nephritis, and IgA nephropathy).

In order to clarify the diagnosis, guide treatment or judge the prognosis, and when there are no contraindications to puncture, renal puncture can be performed for various primary, secondary and hereditary renal parenchymal diseases (especially diffuse lesions) in internal medicine.
