Percutaneous image-guided biopsies help better select patients with renal tumors smaller than 4cm. These biopsies are performed to reduce the risks of overtreatment and to discriminate between patients who need ablation therapy and those who require active surveillance. Percutaneous image-guided biopsies are effective for a definitive diagnosis with little risk of complications when cautions are observed. With the current addition of multiparametric imaging, standardized biopsy protocols may further help adapt therapeutic decisions. The aim of this review is to report the current indications and techniques of biopsy performed in case of small solid renal masses and to clarify the optimal conditions for the realization of these biopsies.
