About renal biopsy (kidney biopsy)

A renal biopsy is a minimally invasive procedure used to collect tissue samples from the kidney for diagnostic purposes. It is especially indicated in cases where renal masses are of uncertain nature and cannot be clearly diagnosed with imaging such as ultrasound or CT scans. The biopsy helps distinguish between benign and malignant tumors and guides further treatment decisions.

It is often recommended for patients under active surveillance (for example, older adults or those with multiple comorbidities) for whom major surgery would pose higher risks.

Medical indications for renal biopsy

1
Small renal masses

For diagnosis and pre-treatment planning, including before ablative procedures.

2
Active surveillance / higher operative risk

Patients at high surgical risk or with metastatic disease, where biopsy results optimize management.

How is the renal biopsy performed?

1. Image guidance

The biopsy is performed under ultrasound or CT guidance (in our center, typically ultrasound) to precisely localize the renal lesion.

2. Anesthesia

The procedure is performed under local anesthesia (local protocol may also involve general anesthesia) to ensure comfort and optimal immobility during sampling.

3. Tissue sampling

A fine needle is advanced through the skin into the kidney to obtain core samples from the target area. Total duration is approximately 30–45 minutes.

4. Post-procedure monitoring

After the biopsy, the patient is observed for a few hours to detect early complications (e.g., hematuria).

Preparing the patient for renal biopsy

  • Suspension of anticoagulant therapy

    Temporarily stop blood thinners a few days before the procedure, as instructed by the treating physician.

  • Blood tests

    Check coagulation (INR, APTT, platelets) and renal function before the procedure.

  • Hydration

    Maintain adequate fluid intake, as advised, to lower the risk of complications.
