Abstract | OBJECTIVE: The safety and accuracy of active percutaneous needle biopsy for small renal tumors have been reported. However, there have been few reports of passive biopsy for renal tumors without clear pretreatment histological characterization based on imaging studies due to the rarity of these tumors. In this study, we examined the background, accuracy, adverse events and patient prognosis associated with such biopsies. METHODS: Japanese patients with renal tumors histological characteristics of which were unclear on imaging prior to treatment were enrolled in this study and analyzed retrospectively. The study population consisted of 24 renal cell carcinoma patients and 13 non- renal cell carcinoma patients. RESULTS: CONCLUSIONS: Biopsy of renal tumors is safe and accurate regardless of the type of guidance and nephrectomy after appropriate diagnosis by biopsy contributed to longer survival.
