Abstract: Objective To compare the diagnostic efficacy and complications of transperineal prostate biopsy for<10 cores biopsy vs≥10 cores biopsy. Methods Nine hundred transrectal ul-trasound-guided transperineal prostate biopsies were performed. Patients were divided into 2 groups, <10 cores group and ≥10 cores group. Patient numbers of the 2 groups were 759 and 141, respec-tively. Cancer positive rate and complications were compared between the 2 groups retrospectively. Results Cancer positive rates were 41.6%(316/759) and 51.8%(73/141) in 2 groups (P<0.05). In patients of PSA≤10.0 ng/ml, cancer positive rates were 6.8% (16/235) and 17.8% (8/45) in 2 groups (P<0.05). Gross hematuria was the most common complication associated with biopsy. There was no statistical difference between the 2 groups in post-biopsy gross hematuria rate. Conclu-sions The diagnostic efficacy is higher in≥10 cores prostate biopsy than that in <10 cores prostate biopsy, There is no difference in biopsy related complications regarding biopsy core numbers.
