AB  - OBJECTIVES: To evaluate retrospectively the diagnostic yield, safety, and risk 
      factors for diagnostic failure of computed tomography (CT) fluoroscopy-guided 
      renal tumour biopsy. METHODS: Biopsies were performed for 208 tumours (mean 
      diameter 2.3 cm; median diameter 2.1 cm; range 0.9-8.5 cm) in 199 patients. One 
      hundred and ninety-nine tumours were </=4 cm. All 208 initial procedures were 
      divided into diagnostic success and failure groups. Multiple variables related to 
      the patients, lesions, and procedures were assessed to determine the risk factors 
      for diagnostic failure. RESULTS: After performing 208 initial and nine repeat 
      biopsies, 180 malignancies and 15 benign tumours were pathologically diagnosed, 
      whereas 13 were not diagnosed. In 117 procedures, 118 Grade I and one Grade IIIa 
      adverse events (AEs) occurred. Neither Grade >/=IIIb AEs nor tumour seeding were 
      observed within a median follow-up period of 13.7 months. Logistic regression 
      analysis revealed only small tumour size (</=1.5 cm; odds ratio 3.750; 95% 
      confidence interval 1.362-10.326; P = 0.011) to be a significant risk factor for 
      diagnostic failure. CONCLUSION: CT fluoroscopy-guided renal tumour biopsy is a 
      safe procedure with a high diagnostic yield. A small tumour size (</=1.5 cm) is a 
      significant risk factor for diagnostic failure. KEY POINTS: * CT 
      fluoroscopy-guided renal tumour biopsy has a high diagnostic yield. * CT 
      fluoroscopy-guided renal tumour biopsy is safe. * Small tumour size (</=1.5 cm) is 
      a risk factor for diagnostic failure.
