There are two general types of renal biopsies: targeted biopsies (TB) and non-targeted biopsies (NTB). Clinicians may perform targeted biopsies to differentiate the pathologic nature of a mass lesion. On the other hand, non-targeted biopsies are performed to sample a relatively random area of the renal cortex to diagnose a systemic disease or physiologic response of the kidney to a prior treatment (e.g., transplant kidney dysfunction, renal failure after medication administration).
Renal biopsies can also be categorized by the method used to access the specimen. These include
Open surgical approach.
This article focuses on percutaneous image-guided targeted and non-targeted biopsies.
