Answer

Contraindications for percutaneous renal biopsy include the following:

  • Uncorrectable bleeding diathesis

  • Small kidneys

  • Severe hypertension

  • Multiple bilateral cysts or renal tumor

  • Hydronephrosis

  • Active renal or perirenal infection

  • Uncooperative patient

Percutaneous biopsy may be performed in selected patients with a solitary kidney because of the generally low risk of bleeding. Open renal biopsy may be performed if a percutaneous attempt is either unsuccessful or contraindicated and if the benefits of diagnosis outweigh the risks. When percutaneous biopsy is contraindicated but a diagnosis is necessary, a transvenous transjugular renal core biopsy can be performed. [11] With this approach, bleeding occurs intravascularly, thereby reducing the risk of hematoma.
