These Kidney Patients Can not Do Renal Biopsy

These Kidney Patients Can not Do Renal BiopsyAfter the diagnosis of kidney disease, the doctor will give the patient a clinical diagnosis. However, if the disease is more serious and the pathological type is difficult to be determined by laboratory examination and clinical manifestations, renal biopsy may be considered.

Renal biopsy is a costly and invasive procedure that many patients are reluctant to perform. And in fact, not all renal patients need to do renal biopsy.

Who need to do renal biopsy?

  1. Acute nephritis syndrome: renal biopsy should be performed as soon as possible when renal function deteriorates sharply or if acute glomerulonephritis is suspected; Renal biopsy should also be performed if the condition does not improve after 2-3 months of treatment for acute nephritis.
  2. Proteinuria lasted > 1g/ day, and the diagnosis was unclear.
  3. Secondary or hereditary renal disease: renal biopsy should be performed when the disease can not be diagnosed clearly or clinically confirmed but requires pathological results to guide treatment or prognosis.
  4. Acute Kidney Failure: renal biopsy should be performed when the cause cannot be determined by clinical or laboratory tests.

Who can not do renal biopsy?

These renal patients can not do renal biopsy when they have the following conditions.

  1. Obvious bleeding tendency
  2. Severe hypertension
  3. Mentally ill or uncooperative
  4. Solitary kidney
  5. End-stage contracted kidney

The following patients can do renal biopsy when determining the pathological type, but it is usually not suggested.

  1.  Active pyelonephritis
  2.  Renal tuberculosis
  3.  Hydronephrosis
  4.  Renal abscess or peripheral abscess
  5.  Renal Tumors
  6.  Polycystic Kidney Disease (PKD)
  7.  The kidney position is too high
  8.  Severe ascites
  9.  Obesity, etc.

After the renal biopsy, the patient should lie on his/her back for 20 hours, and at the same time, check whether there are complications, such as hematuria, perinephric abscess, arteriovenous fistula, infection, and puncture of other organs by mistake, etc. If the condition is stable and there is no gross hematuria, you can get up from the bed after 20 hours.

All in all, If moderate to severe proteinuria is not alleviated after treatment, or the renal function is reduced for unknown reasons, and the disease is indeed undiagnosed, renal biopsy should be performed to clarify the disease.

However, if it is a kidney patient who only checked the simple qualitative and quantitative analysis of urine protein and did not carry out a more detailed examination and diagnosis of urine protein, he/she should firstly find a large hospital to check the composition of urine protein. Although the diagnostic accuracy of renal puncture is high, it is a waste to do it when the laboratory examination is not enough.
