of biopsy. One or more SR were found in 168 men (83.6%). They were PIRADS 2 in 20 men (11.9%), PIRADS 3 in 61 (36.3%) and PIRADS 45 in 87 (51.8%). Under local anaesthesia and antibiotic prophylaxis, two cores of the most suspicious areas were obtained by CF-TRUSGB, and thereafter a 12TRUSGB was performed. End points were detection rates of PCa and high grade PCa (HGPCa: Gleason>6). Efficiency was calculated as the number of cores needed to detect one PCa and one HGPCa. RESULTS: PCa was diagnosed in 53 of 168 men (31.5%), 44 of them (83.0%) by 12TRUSGB and 38 (71.7%) by CF-TRUSGB, p1⁄40.047. HGPCa was present in 39 men (73.6%), 31 (79.5%) in 12TRUSGB specimens and 33 (86.4%) in CF-TRUSFB ones, p1⁄40.024. 12TRUSGB missed 9 PCa (17.0%), being 8 of them HGPCa (88.9%), and CF-TRUSGB missed 15 PCa (28.3%), being 4 of them HGPCa (26.7%), p1⁄40.026. 12TRUSGB needed 53.5 cores to detect one men with PCa and 75.9 to detect one HGPCa, however CF-TRUSGB needed 12.3 and 14.1 respectively, p1⁄40.001. CONCLUSIONS: We conclude that CF-TRUSGB, in men scheduled for repeat PB, helps us to improve the detection of HGPCa and is more efficient to detect PCa and HGPCa. However, we can not avoid the performance of 12TRUSGB since 15 PCa were missed by CF-TRUSGB.
