Introduction : In the current era of nephron-sparing surgery (NSS) for localized tumors, pretreatment tissue biopsy is being revisited and re-evaluated. Whether a renal biopsy can supplement imaging investigations to change patient management is a subject of current research. Materials and Methods : We performed a database search in PubMed for manuscripts from 1988 to 2008 using the appropriate keywords. Manuscripts were selected according to their relevance to the current topic and incorporated into this review. Results : Preoperative renal biopsy has been utilized to effectively distinguish between benign and malignant tumors localized to the kidney with minimal additional morbidity attributable to the procedure. Tissue diagnosis can also potentially grade renal tumors and uncover unusual malignancies. Although its acceptance remains limited, with fear of false negative results, bleeding and tumor seeding, its ability to influence management decisions has been demonstrated in literature. Conclusions : The role of preoperative renal biopsy for localized renal tumors is likely to increase rapidly in the coming times. With the expanding scope and utilization of NSS, this diagnostic modality will find increased applicability and acceptance in individualizing management protocols in the future.
