Gold standard kidney biopsy

For the diagnosis of unclear kidney disease

A kidney biopsy is the gold standard for diagnosing unclear kidney disease.
It is performed daily in our department and requires the patient to be monitored in hospital for 24 hours. Anticoagulant medication such as aspirin or Marcumar must be discontinued in good time (at least 1 week in advance) and subcutaneous heparin injections must be stopped at the latest the evening before.

The procedure is performed under constant visual control using ultrasound. The patient lies stretched out prone on a stretcher; the left kidney is adjusted sonographically and the puncture site is marked on the skin. The skin, subcutaneous tissue and muscles are anaesthetized using a local anaesthetic; the kidney itself is not sensitive to pain.

Under sonographic control, the biopsy needle is then moved through a guide rail towards the lower pole of the kidney. At the push of a button, a 1.6 - 1.8 cm long and 0.9 mm wide tissue cylinder is punched out of the kidney within a tenth of a second. The tissue sample is then presented to our pathologists for diagnosis.
After removing the biopsy needle from the puncture channel, a normal plaster is sufficient to cover the small skin defect.

The patient must now lie on their back on a sandbag for a few hours to create pressure on the puncture site and prevent a hematoma. Bed rest is required the following night.

The patient can get up again the next morning after a check-up ultrasound and - if no immediate treatment is required - go home. Carrying heavy loads should be avoided for the next 14 days.
