instability, the patient should receive adequate clinical measures at an intensive care unit, followed by an angiographic study. Digital angiography remains the gold standard for the anatomic study of the renal arteries, but computed tomography angiography (angiotomography) has gained popularity, offering comparable accuracy and the advantage of evaluating not only the lumen, but its walls and other

*Endovascular embolization. (A) A catheter is inserted into femoral artery, by the groin area to access vessels of the kidney and into vascular rupture site. (B) Rupture in arterial blood vessel, which will receive a catheter* 

*Renal arteriography, 2 hours after percutaneous native kidney biopsy. (A) Pre-embolization arteriography revealed pseudoaneurysm in a lower renal pole (yellow arrow). (B) Post-embolization superselective arteriography revealed absence of pseudoaneurysm with preservation of the local vasculature (yellow arrow).*

> Imaging-guided renal biopsy is a useful tool for the evaluation and management of renal diseases. This chapter summarizes that percutaneous ultrasound-guided renal biopsy is a safe technique which allows the evaluation of renal disease but is associated with post-biopsy complications. We discuss indications and approach to imaging-guided percutaneous renal biopsies as well as complications and management associated with this.
