The changing trends of image-guided biopsy of small renal masses before intervention —an analysis of European multinational prospective EuRECA registry

ConclusionAn increased use of pre-cryoablation biopsy was observed and cryoablation patients treated with a benign histology are more likely to have presented in periods where pre-cryoablation biopsy is not as prevalent. Comparative studies are needed to draw definitive conclusions on the effect of pre-cryoablation biopsy on SRM treatments.Key Points•The use of biopsy pre-ablation session has increased significantly from 42% of all patients in 2015 to 74% in 2019.•Patients are less likely to be treated for a benign tumour if they presented later in the trend, where pre-cryoablation biopsy is more prevalent, compared to later in the trend (OR 0.64, 95% CI 0.51 –0.81, p< 0.001).•Patients with comorbidities or a complex tumour (R.E.N.A.L. nephrometry score> 10) are less likely to not undergo biopsy as a separate session to cryoablation.
