Renal Tumor Biopsy Technique / 中华医学杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To review hot issues and future direction of renal tumor biopsy (RTB) technique.</p><p><b>DATA SOURCES</b>The literature concerning or including RTB technique in English was collected from PubMed published from 1990 to 2015.</p><p><b>STUDY SELECTION</b>We included all the relevant articles on RTB technique in English, with no limitation of study design.</p><p><b>RESULTS</b>Computed tomography and ultrasound were usually used for guiding RTB with respective advantages. Core biopsy is more preferred over fine needle aspiration because of superior accuracy. A minimum of two good-quality cores for a single renal tumor is generally accepted. The use of coaxial guide is recommended. For biopsy location, sampling different regions including central and peripheral biopsies are recommended.</p><p><b>CONCLUSION</b>In spite of some limitations, RTB technique is relatively mature to help optimize the treatment of renal tumors.</p>
